How loud is a GX CS4 Compressor? It’s not bad at all – what I also learned is that cheap sound level meters aren’t consistent

There’s an old saying that nobody is sure of where it came from that says if you have one clock you know the time. If you have more than one, you are never quite sure. The reason for this is that if the clocks have different times then which is wrong or right? Well, I guess now we have time servers, atomic clocks and what not to help answer “what time is it?”.

Now why did I open with that? Well, the only sound level meter I had to measure the decibels of anything was my phone and two different apps that kind of agreed. When reading reviews, folks would say that phone sound level apps were not accurate. Well, I decided to buy a sound level meter to be more accurate … that was in 2017 and I thought I knew how many decibels things were using my cool BAFX3608 meter.

Fast forward to February 2023

I decided to test my GX CS4 and I also wanted to test some airgun moderators so I thought I would order in a few more inexpensive sound level meters to get readings in different spots – a BAFX3370, a Tadeto SL720 and a XRCLIF-1359.

I was using my GX CS4 compressor to top off my 6.8 liter carbon fiber bottle and thought it would be a great time to get sound readings from relatively the same location. I lined them up and took a video to capture sound readings on each meter at a certain time by freezing the video.

Here’s the video so you can hear the compressor and see the meters:

How did they do?

Well, I recorded the readings at 4,11, 16, 21, 26 and 31 seconds. I then calculated the average of the four and compared the meters to the average. The BAFX 3608, BAFX 3370 and XRCLIF were closest. The Tadeo was introducing quite a bit of variation into the samples. With one exception at 26 seconds, it always registered the lowest decibels. Excluding the Tadeto, the average spread was 2.97db across the three meters. With the Tadeto, the average spread increased to 6.8db.

By the way, the manufactures claim +/-1.5db of accuracy for the two BAFX meters, +/-2.0db for the Tadeto and +/-1.5 for the XRCLIF. That means the ranges should have been at most 3.5db apart. The recorded data showed spreads far wider than that.

What this spread tells me is that the two BAFX units and the XRCLIF are in relative agreement given their stated accuracy. My tendency is to think they are closer to whatever the real measurement actually is and discard the Tadeto data. It also tells me that when you buy cheap uncalibrated sound meters you get cheap uncalibrated sound meters.

What about the apps?

I tried the both the “Sound Analyzer” and “Sound Meter” apps for my Samsung Galaxy S20FE. The Sound Analyzer reported an average of 79.3 and the Sound Meter app averaged 80. The sampling was done by holding my phone about the same distance from the CS4 and letting each app collect data for about 30 seconds. Given how fast the CS4 pumps, the apps had quite a few cycles to record.

This is a screen capture of the Excel file I created to look at the data.


I have a vague idea that the average sound level was somewhere between 81.5 to 86.1db as the machine operates if I exclude the Tadeto’s recordings. The samples were drawn at different times and the pump had a repetitive rhythm to it so I am sure the volume did differ but looking at the spread across the meters and the deviation from the average tells me that three meters are closer to one another (the two BAFX models and the XRCLIF) and the Tadeto is an outlier. The apps don’t really agree with anything either.

To wrap it up, thanks to my PC periodically synching its clock to a time server, I know it is about 9:20pm right now. What were the actual sound levels during each of those samples … now that I don’t really know with any precision – I have a ballpark range. I guess some day I will need to buy a quality calibrated sound level meter – what I probably should have done from the start. If you need to buy a meter and can’t afford a higher end unit – buy either the BAFX 3370 or the XRCLIF-1359. The BAFX 3608 is no longer made (as mentioned – I bought it back in 2017).

Note, I have to buy all of my parts – nothing here was paid for by sponsors, etc. I do make a small amount if you click on an ad and buy something but that is it. You’re getting my real opinion on stuff.

Are you trying to save money and time on firearms and related items? Try Gun Deals

In searching on the web, I’d seen links to Gun Deals once or twice but never bothered because of the name. My mental scam filter is always set to high in other words. They recently reached out to me about their service so I took a look and was surprised.

Gun.Deals – yeah, that really is their website but wha I didn’t know is that it is a free to the user search engine where you can plug in what you are searching for – firearms, ammo, optics, lights, knives, etc. – and then they return listings at various websites so you can see the prices. You can then click on a result to learn more or order directly from the merchant’s website you go to – Gun.Deals helps you find the deals but they aren’t the actual seller, which is just fine. You can go to merchants you like and skip ones you do not.

They have advertisements and ways for vendors to post listings so I sure they have a number of ways to make money but it is not off you. It’s the same as you using any other search engine but they have tuned Gun.Deals for the things we care about.

One of the biggest value adds in addition to just finding items and seeing their prices is whether they are in stock or not. They also split out “in stock” vs. “out of stock” listings via their real-time inventory information, they can save you time and frustration as well. A pet peeve of mine is searching for something and going through website after website of vendors listing the product but not having it in stock.

Screen Shots

So you can get an idea of what the site looks like, I just went to their main page while writing this post:

This is their main page that came up for me just now. I then entered “Glock 29” in the search bar.
It came up with both the Glock 29 Gen 4 and the SF. I clicked on the Glock 29 Gen 4 and the above is what came up. It separates listings that are in stock from out of stock automatically and that is really cool.


With money tight these days, add Gun.Deals to the websites you go to for checking prices, finding deals, etc.

PSA AR Build Kits Are Affordable and Fun To Build

I’ve pointed thius out before – I really enjoy building firearms. I don’t have the hardcore machinist skills to build one from scratch – I wish I could though – but I do enjoy assembling and tinkering plus I don’t mind some fitting / fabricating. With this in mind, I have a lot of fun building ARs from PSA kits because they are affordable, reliable and accurate. I’m not going to waste time with the whole manufacturing tiering or the rediculous “poor” labels – that’s all they are. Now, if you are in the military and you need special weapons, you aren’t reading this post – it’s that simple. If you are like most folks and want to build an AR that you can enjoy with friends and family, then read on.

Founded in 2008

For those of you who do not know Palmetto State Armory (PSA) – they have been around since 2008. It was founded by Josiah McCallum after his Iraq deployment and he started it in his garage. To put it mildly, he has been growing PSA ever since into the powerhouse it is today. Folks, PSA has a ton of offerings now – ARs, AKs, pistols, ammo, parts … the list goes on and on. One thing you will notice is that they are constantly learning and evolving.

I’ve Only Had One Problem

So, I bought and built my first PSA AR many years back – I looked at my order history and it looks like it was 2014. In all the years, I can only remember one problem – they forgot to include the disconnector. I contacted customer service and had one a few days later. That was probably a year or two after my first one and I’ve not had a problem since. You’ll notice now they bag their parts by grouping so this probably helps with quality control considerably.

Have I ever had a part fail? No – not that I recall. I normally will put a few hundred rounds through a build, eventually get bored of it and have my FFL, Michigan Gun Exchange, sell it to fund another project. So all I can tell you is that my experience with their AR kits has been very favorable and have no reservations telling someone to use them – especially if they want to start and learn.

What options do they have?

Whew – they have tons and tons of kits and parts you can choose from. Different barrel lengths, handguards, furniture, triggers, and so forth. You can buy a kit with everything except for a stripped lower receiver or you can buy assemblies such as a build kit for a stripped lower to then use with whatever upper receiver you want.

The point is that they have something for everyone and if you are patient and watch their Daily Deals (you can sign up for their emails) then you can get a great deal. For example, the kit I built this time is their “PSA 16″ 5.56 NATO 1:7 MIDLENGTH NITRIDE 13.5″ LIGHTWEIGHT M-LOK MOE EPT RIFLE KIT W/ MBUS SIGHT SET” – which means in has a 16″ barrel that is chambered for 5.56 NATO with a 1:7 twist and black nitried finish, has a 13.5″ M-LOK handguard, comes with Magpul MOE grip and buttstock, their enhanced polished trigger (EPT) fire control group and has a set of Magpul BackUp Iron Sights (BUIS). Yeah, they pack a lot into that description. The kit comes with everything you need except for a stripped lower receiver (I used an Anderson I already happened to have) and the best part was that it was only $479.99 vs. the list of $799.99.

This is PSA’s Model 516446780 parts kit that comes with everything you need except for a stripped mil-spec lower receiver.

Serves as a foundation

The AR parts are all Mil-Spec – what this means is that rifles that use parts built to the original military specification dimensions can use other parts. For example, I prefer the Magpul ACS stocks – they just feel better to me. Because the PSA buffer tube is Mil-Spec, that meant I coul easily replace the MOE buttstock that came with the kit with an ACS.

My point is that a PSA kit can serve as a foundation that you can very readily build on. Down, the road if you want to change out barrels, triggers, uppers, etc. you can easily do so. If something has a problem and you need to replace, again, there will not be a problem finding parts.

By the way, I would recommend a spare parts kit regardless of brand AR you are using – they are usually relatively inexpensive and include wear items, such as the firing pin, plus parts that get lost – for example, the takedown detents.

A quick comment on the EPT triggers

The PSA EPT triggers are a decent. I recently did a test on a number of triggers and a Mil-Spec Aero brand trigger had an average pull of 6 pounds 12.4oz. The PSA EPT had an average pull of 6 pounds 12.3oz and that was with both lubricated by oil. So, not a huge benefit but I do like them – just don’t expect a world of difference is my point.

If you really want a remarkable trigger, buy the PSA 2-stage trigger that has an average pull of 4 pounds 9.5 oz when lubed. It’s a must-have upgrade for only $64.99 and yes, you can always change to it later.

How do you assemble these kits?

Really, the only thing you need to assemble is the lower. PSA has already done the upper and headspaced it just to be safe. In theory, Mil-Spec barrels going into Mil-Spec uppers should not need headspacing but the reality is that you better check it just to be safe and PSA does.

I did a whole series of posts back in 2017 about building AR lowers – click here for a list that will open in a new browser tab.

The reference source I used to learn how to assemble AR lowers way back when is the guide on There are now tons of videos out there as well and you can learn a great deal by investing a little time to watch them. For example, here is one from PSA and here is one from Midway USA.

This is my latest 16″ PSA AR build. It has a MOE stock, Magpul BUIS and a Vortex Optics UH-1 sight.

Recommended Tools

Over the years, I have bought and tried quite a few tools but there are just a few that have stood the test of time that I still use. I figured it might help you to have a list so you can consider whether you want to pick them up or not.

  • Trigger Guard Jig – there are a ton of ways to do the trigger guard roll pin but a tool makes it really simple and reduces the odds of marring the finish or snapping an ear off the receiver.
  • Magazine Catch Punches – folks, Wheeler and others make long roll pin punches that have a vinyl coating to help install the mag catch. They are totally worth it. No more tearing up your finish or having to apply duct tape – these tools help you get it right the first time.
  • Front Pivot Pin Detent Jig – installing front pivot pin’s detent and spring is next to impossible without the right tools. Wheeler and others make a very simple pin set to help you save your sanity.
  • Trigger slave pin – greatly simplifies installation of the assembled trigger, disconnector and spring assembly. We make one 🙂
  • Magpul Castle Nut Wrench – I have used a wide variety of tools over the years ranging from the old GI tool to bizarre looking combination wrenches. If you want a solid tool that will hold up over time, the Magpul wrench is the way to go.
  • Gunsmith Punch Set – there are tons of makers. Basically you want a wide range of punches and roll pin punches. I have a mix of punches from Tekton, Weaver and Wheeler plus ones that I have no idea where they came from.
  • Non-Marring Hammer – You’ll need a small hammer from time to time that will not tear up your finish – I use Vaughan hammers.
  • Automatic Punch – I have a tremor so my hands shake. To stake the rear castle nut, I just use a good General brand automatic punch. It’s not as deep/good of a stake as a hammer driven punch but I do the automatic punch repeatedly to deform the surface and lock the nut.
  • Magpul BEV-Block – If you plan to install barrel nuts or muzzle devices, you will need a really secure means to hold the barrel and receiver securely. DO NOT use the blocks that just use the pivot and rear pin holes your you are apt to bend them. I did that once. Get a BEV block. It’s way, way easier and does a great job.

In Conclusion

If you are looking for something fun to do and there are tons and tons of tutorials out there – build an AR. The PSA kits are reliable and very affordable with different options to suit your tastes.

Note, I have to buy all of my parts – nothing here was paid for by sponsors, etc. I do make a small amount if you click on an ad and buy something but that is it. You’re getting my real opinion on stuff.

How to level a scope reticle

First off, I better explain that a recticle is the formal name for the cross-hairs or series of fine lines that are inside a scope that you use to aim with. There are a ton of different ones out there and one thing you want to do is to get them level with the rifle.

Let’s start with why this matters

The reason for this doesn’t affect the old traditional cross-hair designs but it does the ones that have additional marks to help you better determine the range and the necessary hold based on Mil-Radians (Mils) or Minutes of Angle (MOA).

These are examples of reticles found in a very interesting post about the topic on Wikipedia.

If you search, there are tons and tons of posts about different types of reticles and how to use them. The important point I want to make is that for any of these more modern reticles with additional lines to help you accurately, the horizontal lines must be parallel with the rifle.

How do you level a reticle?

The first way is the old fashioned “eyeball” method. Hold the rifle and make sure the top of the receiver is as level as possible (meaning the rifle is not tilted left or right), look through the scope and adjust it in the rings until it is true to the top of the receiver and then start tightening down the rings while confirming nothing shifts. It’s not the most precise method but it does work, I’ve done a ton of rifles that way, but there is another approach using levels.

In it’s most form, you put a small level on the top rail or flat spot of your recever, tilt it until it is level and then put the level on the top turret and adjust the scope until it matches. Having something to hold the rifle in place while you work really helps as does having a second level so you can both confirm the receiver and scope are level as you work. You can often find single vial levels at hardware stores or through industrial supply houses. The one negative to this approach is that the levels can slide off if you don’t have things secure. I like to use a Tipton Pro Rifle Vise to hold the rifle in place while working.

Wheeler Engineering does offer a basic level set that works. I don’t use it though because it’s rear receiver piece has a magnet to secure it and that will not work in an AR or other weapon that is made from aluminum and not steel. For this reason, it wasn’t something I could use.

These days, when I have time and I want to try and get the scope as accurately positioned as I can on the first try, I use a Wheeler Engineering Profession Reticle Leveling System. It’s easy and fast.

First, you put the level on your receiver/rail and level the receiver. Then you put the clamp on the barrel and level it – I compare both the receiver and the barrel bubble levels before I move the receiver level to the top scope turret. Once the level is on the top turret, I adjust the scope until the bubbles match and it’s done. I’ve used this for a number of years now and am very happy with it.

The professional leveling system has two parts – the barrel clamp and the separate level you use on the receiver and then the scope turret. The two parts are made from aluminum and come in a nice protective case. If it weren’t for the case, mine would look much more beat up. Protecting the parts makes sense for another reason – you don’t want things to get bent, gouged, dented or whatever and then throw off the readings or mar the finish of your weapon.
The first thing you do is to use the small level (shown behind the backuop sight) to true the receiver. Then you adjust the barrel clamp until it is level also. Just visible under the handguard is the front of my Tipton vise.
After the barrel clamp has been levelled, you move the small level to the flat top turret and then rotate the scope however you need to get it flat also. Compare this level to the barrel clamp level to make sure they agree. The more care you take to get the bubbles centered and matching, the better.

I do use a Vortex torquing screw driver to tighten the scope ring screws and am careful to confirm the scopes levelling does not shift in the process. Vortex scopes say not to torque them past 18 inch/pounds (please note that is inch pounds and not foot pounds just to be very clear – you don’t want to damage your scope but at the same time, you do want it secure).

Again, with any of these methods, it really helps to secure the rifle in a vise where you can adjust and then secure the rifle so the top is horizontally true.

Yeah, this is my real work bench. It was worse than normal as I still had all of the packing from the scope,rings and upper on the bench. The Tipton gun vise has served me very well over the years. By the way, notice the level on the turret – you reall want that perpendicular to the rifle. In this photo it is slightly crooked and no longer perpendicular and risk the scope not bein accurately levelled to the rifle.


The Wheeler Engineering Professional Leveling System has served me well and I have used it on a number of projects over the years. I have no hesitations in recommending it to you as well.

I hope this post helps you out.

Troubleshooting A Pride Mobility GoGo Elite Traveller Scooter’s Power Problem

My mother-in-law is getting older and so are my wife and I. Let me tell you, It was a lot easier pushing around a wheelchair 10+ years ago compared to today. With this in mind, my wife and been watching for a good deal on one of those little electric mobility scooters. Finally, one day she saw one posted on Facebook at a local thrift store so we want and took a look.

The owner of the store buys abandoned storage units and a Pride Mobility Elite Traveller scooter was in one of them. It looked to be in great shape but it wouldn’t run. He could turn the on/off switch and a light would come on the little dashboard but that was it. He said he tried charging it for an hour but nothing happened and thought it was the batteries — this is a great example of someone giving you their diagnoses and then that affects what you do.

At any rate, it came with the original Pride Mobility charger so I figured it was probably the batteries and did a quick search on them and replacements ranged in price from $51-89/pair. With this in mind, we settled on a price of $250 and brought the scooter home.

Here’s the GoGo Elite Traveller scooter. It’s remarkably well made. I was impressed the minute I started critically looking at the fit, finish and serviceability.
Note: Pride Mobility puts all of their manuals online. I really appreciate it when firms do this. You can get the brochure, owner’s manual, specification sheet and more on their website – click here. Just FYI: They do not provide a repair manual or technical guide.

A few days went buy before I could work on it. The first thing I did was plug the charger into the wall, then the cord direct to the power pack, turned on the switch and the little red power light came on. The charger’s second indicator LED was supposed to turn yellow that it was charging. It did not – it stayed off. Also, the cooling fan never started. Hmmm…. interesting but I had run into problems before with smart chargers not starting if batteries were dead.

Now, this mistaken assumption cost me some time but I learned a lot in the process that I’ll share.

Removing And Opening The Battery Compartment

Based on what I saw, the engineering and build quality of the scooter was excellent. I’ve seen people driving them around but never had the need to look at one up close or take one apart. Everything is built heavy duty with reliability and resiliency in mind not to mention they put fuses all over the place to protect the electronics. With that overview comment done, my focus was on getting to the batteries because I thought that was the problem.

The battery pack is the black plastic “box” with a molded handle directly underneath the seat on the floorboard of the scooter and is held in place by a tab of 3M Dual-Lock fasteners on each side. Dual-Lock is a stronger than traditional velcro and it does a great job of holding the battery compartment in place both for the sake of safety as well as to prevent rattling.

To remove the battery box, lift straight up – there aren’t any bolts or clasps – just a combination of weight, the way the pieces fit together and the Dual-Loc. If you try to lift at an angle, you’ll be surprised how it will not want to budge – straight up is what you need to do.

That black molded plastic object with the handle in front of the silver set mast is the battery compartment. It comes off the scooter by lifting straight up. FYI – the white label on the seat mast has the date of manufacture.
Between the way the compartment sits into the molded floorboard and the 3M Dual-Loc tabs, the unit is very secure.

The battery compartment is very well made and to disassemble it, you need to remove six philips head machine screws. This is just an example of where I thought the design and execution was excellent – these are threaded machine screws that go into brass female inserts on the other side – they didn’t just go cheap using some self tapping screw. You flip the compartment upside down and remove the screws. The batteries are held securely in place by Dual-Lock also.

The 12 Volt Batteries Themselves

I’m going to step you through some details on the batteries but I did not change them yet. I’d recommend you read this whole post because your “problem” may or may not be the batteries.

Our scooter is powered by two 12 volt 12 amp hour batteries wired in series to provide 24 volts. In the compartment is a wiring diagram and everything is done very nicely to avoid confusion – red wires to positive tabs on the battery and black wires to the negative tabs on the battery.

These are the 12 volt 12 amp hour batteries that are hooked up in series to provide 24 volts. If you look to the right of the silver plug, the two red wires white plastic connector is on a fuse assembly that protects the charger circuit that you will want to check and the far right side has a circuit breaker that is also worth checking. Pride says they can go up to 6.7 miles depending on factors such as the weight of the passenger and cargo. Note how everything is so well labeled, the wiring is very neatly done and they even provide a handy wiring diagram above the left battery. Whomever designed and then built this cared about what they were doing.

For those of you unfamiliar with direct current (DC) batteries, these two batteries are hooked up in series to produce 24 volts. This is done by connecting the negative terminal of one battery to the positive of the other and then the opposite as well. In the scooter, this is done at the wiring block in the middle. You don’t need to worry – just note the wires when you take it out (a photo helps) and do a battery at a time – black wire to negative and red wire to positive,

Note, there are at least two sizes of batteries used – their standard battery pack is rated for 6 miles and uses two 12 amp hour (Ah) batteries. There is a 9.7 mile bigger 18 amp hour (Ah) battery and it correspondingly uses a bigger cabinet so if you decide you are going to replace your batteries, confirm what is in your battery compartment first. You can change cabinets – or even buy entire battery packs ready to go. From what I have seen, the cheapest bet is to just buy the batteries and swap them out in your existing compartment. I also see batteries with other capacities like 15Ah and over 20Ah, I’d recommend you confirm that their physical sizes will fit whatever battery compartment you have.

Troubleshooting the HP8204B Charger

The batteries hold the charge that runs the scooter but they must be recharged by using a battery charger. I should have checked this first but didn’t because I assumed it was the batteries but let me step you through what I did.

I put a voltmeter on each of the 12 volt batteries and they both read just a tad over 4 volts. So, not absolutely dead but boy were they spent. In doing automotive work, I would have expected the smart charger to sense the voltage and begin. Okay, something was fishy and it wasn’t adding up. It was time to look at the charger again.

The scooter came with a Pride Mobility HP8204B charger rated for 24 volts DC at 5 amps. That would mean that if I took my meter and put it on the pins, I should read somewhere around 28+ volts (the exact volts is an “it depends” – I would have been cautiously happy with anything over 24 and stopping somewhere around 30).

This is the original charger. Only a solid red light would come on. That indicated it had power. The cooling fan never turned on and the second LED that should turn yellow for charging or green for fully charged never turned on.

I used my multimeter on the batteries with the Pride charger connected. Only the red bulb on the charger was lit. No fan, no yellow light and no additional voltage detected on the battery terminals. I should have read 13-14 volts when doing the positive and negative tabs on each individual battery with the wires connected but I read just the 4 volts (by the way I word it like this because it was 4 and some decimal but I didn’t write down.)

The fuse you can see outside of the battery pack between the plug and a circuit breaker on the front of the battery pack looked fine and tested okay for continuity.

In looking at the battery pack, I unplugged the pin 1 should have been positive and pin 2 should have been negative. I cautiously touched my probes on the two tips because I didn’t want to unnecessarily short the system out by accidentally touching positive and negative together. Guess what? Nothing – not a thing. My auto-ranging digital meter was doing it’s usual millivolt reading garbage but there was no real voltage coming through.

The next thing I did was to turn off the original charger and remove the fuse from the end of the charger with the lights – undoing the round cap will produce a glass tube fuse. You can usually see if the wire running from one end to the other in the middle of the clear glass is intact or burned out. It looked okay and just to be sure I ran a continuity test with my meter and it was okay.

I also pulled apart the plug that goes into the battery pack just in case something was lose and it read zero volts too. In case you are wondering why there are three pins (I wondered why) – pin three provides voltage to the scooter so the little computer knows the charger is still attached and will not let the driver move the scooter – pretty good idea.

Okay, it was time to Google the scooter and the charger to learn more. The fact that only the red light was coming on but not the fan and/or the yellow charging light was making it look the the charger had failed. I did the “sniff” test to see if I could smell if anything had burned out but if it had, it must have been some time ago as I didn’t detect anything. In short, the charger was history.

There are tons of charger options on Amazon but I want to caution you against the little sealed chargers. They do work but they are going to get hot and they will probably fail at some point due to all of that heat. There’s a reason Pride went with the a fan cooled charger – they get hot converting AC (wall outlet) current to 24 volts DC (direct current).

Companies like Pride rarely make their own chargers. They will either use an existing charger on the market and not bother covering up the name of the maker or they will pay for it have their brand name on the decal. Pride opted for the latter or at least that’s what I think they did. The trick to realize here is that by searching on HP8204B, you can find either the original maker or another firm who did the same thing – had their name put on the charger. Regardless, you can save a bundle off a new Pride charger.

In my case, I found a seller named “ENCAREFOR” on Amazon selling what seemed to be the exact same charger but with the label “High Power” on it. Besides the label, the rated output is at 4 amps vs. 5 which means it will just charge a tad slower. It was going for $89.99 with Prime One Day shipping but I held off as I realized I needed to test the batteries and the scooter before I spent more money. In other words, I knew the charger was bad but didn’t want to spend more money if the scooter itself was burned out – if it was just the batteries, I could still order them.

By the way, you can buy used OEM Pride chargers off of eBay. I’ve had mixed experience with used chargers in general so I tend to just buy new. If you don’t mind gambling on a used one, they are on eBay.

Used a Noco Genius Car Battery Charger For Testing

At this point I was pretty sure it was charger and also thought that the batteries might be okay. Why? First off, there is a sticker on the mast pole of the seat that said the scooter was made in 2019 – that meant it was three or just under three years old (especially given I was doing my troubleshooting in mid-February 2022). Batteries can last maybe five years give or take. If the voltage was zero, I’d bet they were junk but since I was getting just over 4 volts from each battery independently, they weren’t completely dead. I started to wonder if a good reconditioning and charge might work to bring them back to life. I had just the charger to try.

I’ve written in the past about Noco products – I think they are great and I use mine regularly. Not only are they excellent smart chargers with a number of safeguards built in but they can also recover/recondition deeply discharged batteries as well. My big Noco G26000 can do 12 or 24 volt batteries but since I was planning on a battery at a time, I just needed the 12 volt option. Indeed, I have three Noco Genius chargers of varying sizes (meaning the amps they put out) and they all could have done the job although the smaller 5 amp charger would have likely taken longer.

Any 12 bolt charger can do the job provided you charge the batteries one at a time.

I undid the battery cables from the first battery only and directly connected the Noco to it. I charged for one cycle and then ran a repair cycle. During repair, the charger pulses the battery to desulfinate it.

Don’t let all the wires intimidate you. I hooked the plus (red) clamp of the Noco to the plus (red) terminal of the battery on the left, I then hooked the negative (black) clamp from the Noco to the black terminal of the same battery. I have a small voltmeter that clamps ,on attached also so I could monitor progress — that’s strictly optional.


When the charging was done with both batteries, I connected the scooter’s cables back and seated the battery back into its cradle. I then turned the key on for the scooter and moved it forward and backward. It worked just fine. I checked the batteries and the voltage was holding – it wasn’t dropping down.

This is what I wanted to see — the batteries were fully charged. I drove the scooter around the house and the charge never went down. I also learned that scooters are bizarre little things to drive – their turning is like sitting upright on sensitive go cart.
Other than the decals and the lower 4 amp output, the new “High Power” charger looks identical to the Pride unit. Note, I’d opened the front of the unit up to inspect the inside — the front panel is what is dangling in the bottom left of the photo.
As soon as I plugged in the new charger and turned it on, the red power light and yellow charging lights came on.

By the way, the charger’s fan will make a pulsing or surging sound as the speed changes as it nears the end of charging. This is normal and will give you an indicator that charging is almost complete.

When the scooter’s batteries are fully charged, the yellow light will turn green. The fan will make a pulsing sound as the charging nears completion.

Bottom line, the batteries and scooter were fine – it was just the charger that had failed so I ordered the replacement above from Amazon and it topped off the batteries. I drove it around the house some and everything was working just fine.

In Conclusion

So I learned a few things. The scooter was exceptionally well made is my first comment. Second, I should have started from the wall and worked towards the scooter vs. focusing on the batteries to start based on what the fellow told me.

I should have confirmed power to the charger, then that there was no power from the charger to the scooter and ordered a new charger. I’d bet a new charger could have recovered the batteries – the documentation says they can recondition a battery but who knows. Even though I started with the battery, at least I could run the Noco charger through charging and repair cycles – I’ve used it to recover a number of really compromised batteries over the years.

The scooter is ready and now we need to wait for warmer weather to let my mother-in-law practice in the driveway. I hope this story helps you out.

Still Nuking Mosquitoes and Ticks With Talstar and The Ryobi Power Washer

A reader dropped me an email and asked if I am doing anything new this year for mosquitoes as he read my past posts. I’m still very happy with the effectiveness of the Talstar insecticide plus the combination of the Ryobi 120350 Power Washer and 10-gallon tank strapped to a dolly continues to work fantastic.

Here’s the full write up I did last year about the combination – click here.

I hope everyone has a great summer and be sure to nuke the bugs before they get to you 🙂

June 2021 Lest We Forget Event Was Held in Benton Harbor, MI

Lest We Forget is an organization dedicated to keeping the memories of what our military has done for us. The 2019 event was the last one for WWII, 2020 was cancelled due to COVID and 2021, this year’s event, remembered Korean War veterans. They have static displays, food, vehicles you can ride on and re-enactments.

We arrived a bit late on June 19th due to family commitments but I did have a chance to snap some photos of the various vehicles on display that including a M3 halftrack, a DUKW 6×6 amphibian, an M37 dodge and a M59 APC to name a few.

Here’s the slideshow:

If you ever get a chance to attend a Lest We Forget event, I highly recommend it. The atmosphere is family oriented and everyone there wants to share and have a good time.

The ATN X-Sight 4K 5-20x Scope Is Surprisingly Effective But Expect A Learning Curve

I never was that interested in ATN scopes until maybe a two years ago. I was at the range fiddling with something and a fellow pulled in and set up a varmint AR with a big blocky optic on a Bog Deathgrip tripod. I could not help myself – I had to go over and ask what the optic was.

Thankfully, he was a good old boy and liked shooting and talking. He was having a coyote problem and wanted to get the rig sighted in. He told me it was an ATN night vision optic and the tripod was to help him keep it all steady. I looked it all over and headed back to my area. The ATN looked better in person than it did in the ads that I had seen in catalogs that made it look “gimicky”. Between my assumption about the quality and the price, I was never interested but after seeing it in person it was filed under “who knows – maybe someday” category in my head for future projects.

Fast Forward to 2021

I was researching high end airguns and some of the of guys were running various ATN scopes. I wanted to up my game on the computational ballistics front – yeah the calculation of trajectories – and I wanted a computer to do it for me. I really wanted to get surgical and modern with my new .25 caliber FX Impact Compact pre-charged pneumatic (PCP) air rifle. This desire brought me to ATN and their latest generation of digital X-Sight 4K optics because they have an internal computer that can crank the numbers.

An Auxiliary Ballistic Laser (ABL) good from 5 to to 1000 yards could be added that interfaced with the scope to provide range to target data to the computer. The computer can take the muzzle velocity of your round, the ballistic coefficient of your bullet (in my case pellet), distance of the optic from the center of the bore, angle and the distance to the target and automatically adjust the recticle. Whoa…. that’s pretty amazing.

Just a quick note on the ABL – based on my experience with laser rangefinders, usually maximum range comments by vendor are a bit of hype because it depends on how reflective the target is. In my case, virtually all of my shooting will be within 50 yards with a possible stretch to 100 but I doubt I will ever shoot beyond that.

Another feature that attracted me was the night vision capability. I’ve not had the capability to eliminate pests at night or at very low light levels.

The X-Sight scopes have a host of other features like taking photos and movies, recording just before and after sensing recoil, etc. Those are nice but not really features I cared about.

I shopped around and ordered an ATN X-SIght 4k 5-20x optic, Auxiliary Ballistic Laser (ABL) 1000 rangefinder, and a quick release mount. It came to just over a $1,000 plus I bought a SD memory card. The optic and rangefinder were from Brownells and I sourced the quick detach mount direct from ATN. A lot of vendors carry ATN products so you can shop around.

In case you are wondering why I would go to such expense for accuracy in a PCP airgun that will mostly be used within 100 yards, I can sum it up with the saying “aim small – miss small.” It’s one of my favorite lines from American Sniper but it is true. If you focus your aim on a very small part of the target then you will either hit it or miss by a small amount. This requires discipline and knowledge on your part combined with a capable weapons system to deliver the bullet or pellet.

The Scope, ABL and Mount Arrived

When the boxes came and I started reading the manuals, I had the same feeling when I read something that says “some assembly required”. I really hadn’t put much thought into how different a digital optic is from a traditional scope. Wow. This thing has a series of setup menus and then you need to learn your away around the scope. So right out of the box there was a lot of fumbling, swearing and my changing things.

So here’s my first recommendation – be sure to watch ATN’s videos about setting up the optic and using it. The manuals help but I found the combination of videos for the overview and the documentation to refer to as a very handy combination. Click here to go to the ATN page with all of their videos and/or click here for the manuals – it actually has links to PDFs videos and guidance on the page itself.

The X-Sight is mounted just like any other scope. Square the weapon then the optic to the weapon to ensure the recticle is level. I use a Wheeler scope mounting kit’s leves to do this. Note that the Impact Compact is being held in a Tipton Standing Ultra GunVise. Man, those are nice.

Here’s an example of needing to read the instructions. The threaded portion is part of a tube that is separate from the body of the ABL. You back off the two screws you see, remove the tube and screw it into the front of the X-Sight scope. You then clamp the ABL onto the tube and position it horizontal to the scope and bore.

Here is everything mounted.
Here’s another angle.

Now let me give you hope – once you start using the scope, it gets easier and faster each time. I turn on the scope so it has time to boot up as I am setting up – not at the last minute when I need to take a shot. Most of the time I am shooting at 14 yards so I dont need to range the target and the scope remembers the last range used. Instead,I zoom as needed, acquire the target and take the shot. That’s it – not a billion menus. So, stick with it – you will probably find it frustrating too at first and then it will get better with time.

Setup and Zeroing In Tips

When you are entering the info for the ballistic coefficient (BC) and the muzzle velocity, try and be as exact as possible, I obtained the BC from the manufacturer of my .25 pellets and the muzzle velocity was the average of 10 rounds fired through a chronograph.

I carefully measured out the range from the muzzle to the target. When I entered the range into the optic, I was precise and not guessing. I was being very careful due to the desire for accuracy.

Set your rifle up in a firm stand and fire a group then adjust the recticle. Their marketing comment of one shot zeroes is something they even mention is “in theory”. Repeat this until you have your zero consistently. This will all go faster and be easier if you have a solid stand – notice I mentioned this twice now 🙂 I used a Bog Deathgrip Carbon Fiber model to help me get the job done.

My Opinion

I’ve been using the X-Sight since late-April 2021 and like it. If I have a new distance to shoot, I range it, take the shot and then reset to my most common distance. I have made a few 35-50 yard shots that would have required some calculation, or at least experience, and hit less than quarter sized targets (squirrel head and heart shots) accurately.

Here’s another angle that gives you a good view of the mounted ABL. It connects to the scope via Bluetooth and you need to follow a zeroing process outlined in the manual. It’s straight forward but don’t skip it.

One thing I had to get used to was looking at a small monitor vs. glass. I’ve been shooting nice glass scopes for a number of years now – notably Vortex scopes – and looking at a monitor with a resolution lower than reality is different. I must admit that I prefer the clarity of good glass but it dawned on me that it was not fair to compare them at this point. I bought the ATN for the ballistics calculation capabilities and the potential for low-light/night-use — I did not buy it to be just another scope, That set my mind more at ease about the image difference – it is what it is with the current level of technology in these scopes.

This is an actual screen capture. The optic allows you to select from a number of recticle choices. Note the range information from the ABL down in the ower right corner. What you see in the scope actually has much more information but the screen capture does not include it.
This is an exciting shot of concrete but it lets you see the recticle better.

The combination of scope and ABL is a bit bulky and the ABL’s head is asymmetrical for the laser transmitter and receiver units. I set the Impact Compact on our tall kitchen table and it fell off onto the hardwood floor about three feet. It definitely made my stomach drop to hear all that money hit the floor. I’m actually happy to report that the rifle and optics system survived without any problems at all.

I was wondering how long the battery would live but that has not proved to be a problem. I fully charged it when I first got it and then again a few weeks ago. Now I don’t leave it turned on all the time. I’d say it runs maybe 5-10 minutes every 2-3 days and it’s not been a problem. I think I will just always charge it when it gets half way down or so plus I could always charge it from a powerbank/portable battery if needed. ATN even sells an extended battery if you need it.

The ABL is still on its first battery so I can’t tell you much there – I only use it as needed for longer shots so its had minimal use. I do have a spare battery just in case.

I wish the menus were a bit easier to navigate with very clear “back” or “cancel” options immediately available on every screen. For example, if you get into the manual ranging section or the part of zeroing the recticle by accident. For the most part they are pretty straight forward but I am not wowed by them from a user design perspective.

I opted for the ATN quick connect scope mount and it is okay but does not have locks on the throw levers. In hindsight, I could have used any 30mm rings I wanted including my preferred American Defense mounts. You have plenty of flexibility because one of the menu options lets you specify how high the scope is mounted.

Here’s a view of the ATN quick dtach mount’s levers. They don’t lock closed but have held no problem so far.

Last comment – I had the scope freeze on me twice. I found that turning the ABL off first, if I turned it on, seemed to cause the problem. Now, when I do use the ABL, I turn the scope off first and then the ABL. I’ve not had it freeze since powering down in this order. By the way, if your scope does freeze, hold down the power button for 10-15 seconds and it will shut off – kind of like notebooks where one push does a controlled power down of the laptop but holding it down does a forced immediate shut down.

ATN definitely tries to label everything outside of the scope to try and help folks learn the controls.

In Summary

I’ve been using the X-Sight 4K 5-20 and ABL 1000 laser for about three months and several times per week – sometimes several times per day depending on what is going on. I really feel like the combination has improved my actual accurage in terms of precisely hitting the target so I am happy with the purchase.

I’d recommend the setup for anyone looking for this type of optics system with similar intentions as I outlined at the start. It’s different from traditional glass lense optics but it brings a different set of capabilities to the table also. Let me put it this way,I would buy it again for my intended use.

I hope this helps you.
