Yeah, for the bottle pressure gauge no problemo. But for the HP reg pressure, which controls speed of the pellet, steps of 15 psi (1 bar) is a little wide... IMHO
Unless the gauge in bar goes in 0.1 bar increments then no problem.

1/8 NPT Threaded Digital Gauges to fit the SKOUT Epoch & Airforce Airguns!

I'd prefer PSI for literally everything, don't get me wrong, but in my experimentation with the SKOUT 15psi made very little difference. Ours would shoot the same velocity at like 1020-1060 PSI. Bar would be OK, and definitely better than the cheap analog gauges that come with the SKOUT.
I tried to set SKOUT up with the vendor to include the digi gauges as an OEM component but I am not sure where that conversation ended up between them. Shame because I was gonna get a small royalty per gauge!
Honestly, though, this gun should 100% come with at least 1 digital gauge (for the HPR).Upvote 0
1/8 NPT 300 bar
@Bigragu these look kinda nice actually for the low cost of about 6$. The 340/350 cut off is meh though. Love the name haha Bozo.

That takes a replaceable battery (the one I posted from aliexpress) opposed to the rechargeable internal one right? Looks good.

They also are much thicker, and project at least an inch…not exactly low profile. The gauges that Motorhead posted are the only larger dial, and still relatively thin, gauges I’ve seen in NPT threading.

Such a cheap gauge belongs nowhere near a high end airgun. Please repent now for posting this...

If it weren't for the last hash mark, it would be a mighty fine gauge. All the micro gauges are generally cheap (7-15$) and grade C or grade D. Lol
Just for this comment alone I went and found a cheaper one, that has amazing hash marks in 1/8" NPT / PSI. Thanks, bought a bunch!
4$ 1/8" NPT 0-3000 fine hash mark gauge

The OP stated in the video that “they are very accurate”. I’m going to say he meant they are easy to read a specific pressure digitally. That has nothing to do with accuracy/repeatability. Was the gauge tested along side a calibration gauge and done repeatedly to see if the same reading was shown ? Granted all gauges have a manufacturer stated accuracy. Not bashing but just because it’s digital and easy to read, it doesn’t make it accurate.
When tuning a rifle between different pellets and you found a psi that worked, it may or may not be the correct pressure but you have a reference number for next time you tune to that pellet. And that’s great. But if it’s not repeatable it’s only a nice looking gauge.

I'd like confirmation on this as well, next to a Grade A precision pressure gauge that adheres to ASME B40 / ANSI B40. 1 standards.

I've found that they were super repeatable. We have bought several of these and used them on several different guns, all with great results. I wouldn't recommend it if it were garbage or if I hadn't tested it.
The cheap analog gauges can be off by gigantic margins. They can also leak and get "spun" pretty commonly. I've been in paintball for almost 30 years with a a good 2/3+ of that being a technician, and I've seen my fair share of cheap gauges pooping the bed in a variety of ways. More than my fair share. I would definitely not put a $4 gauge on a $2000 gun, that's just silly and it hearkens back to the phrase "poor is a mindset not a financial condition".

Repeatability ≠ accuracy. The inexpensive analog gauges I bought have only been off by margins within their grade (5%) and no greater which is easy to calibrate at home if one desires. None have leaked or spun out on me, although my most expensive gauges have 'spun out'. Hate to break it to ya, but the FX / Wika gauges are made at similar costs to any other micro gauge, if you contact a company that makes them and get a quote for a large number, you may be shocked that they too can be had inexpensively. (Sub 6$)
It's similar to putting down the digital gauges here for 40-60$ when their competition offers 100$+ gauges...the fx digital version is 140$? The Sekhmet is 120$? The Edgun Measy is 130$? The Edgun EDMU ll is 220$?

But repeatability does equal accuracy, actually, for what we're trying to do with it. Let's say the gauge is 10 bar or 140psi off. Doesn't matter. As long as it shows the same value for the same pressure every time then that repeatability is what allows us to get a good tune. Not saying these digi gauges aren't accurate, as I believe they are - and they are for SURE more accurate than the stock gauges supplied on the SKOUT. I mean, even looking at that tiny needle on the factory gauge leaves a ton of room for error in determining your exact pressure.

So what you're saying is being grade D (5%) off even with inexpensive analog gauges doesn't matter.
Personally I find my 4-10$ gauges sure are repeatable.
Most if any of these micro gauges aren't super accurate. I think it boils down to preference. I only reference my guns pressure gauge to determine if I dropped off the reg anyhow, not for pinpointing a precise regulator set point or swings in pressure from creep...need more expensive equipment to be exact, however these digital gauges should outperform any analog gauge in that regard. I am not familiar with any analog gauges be them 5$ or 25$ that can give a precise readout down to 1 bar or 10-15 psi with pressure changes, and frankly I am uncertain of how sensitive these digital gauges are to environmental changes that might exceed your guns actual changes to the same environment.

All those gauges with the orange hands that look attached to a spring all come from the same place and are super-unreliable. They drift by as much as 20% over time, and in as little as 20 PCP charging cycles (judging by the difference with what the gauge on the pump/compressor says).
Pick an "FX style" gauge that have proper axles for the hand, like the last 2 on this pic. They can be found here (link).
