I have a FX Royale and an FX Impact. I have Joe's Great White carbon fiber tank. There's a 20 bar difference between what Joe's gauge reads and what the gun's gauge reads. On the Impact I normally fill to 230 bar and it's a 250 bar gun. after a fill I checked the gauge on the Impact and it was at 250 bar and enough above it, I dry fired about 10 shots to get it back under 250 bar. I'm not really afraid of something bursting and injury, but I only want to work with the pressures determined by the FX engineers. What gauge do I trust?
What gauge to believe!

I would go by the gauge that has the highest pressure until you can get them tested and calibrated.

I would go by the tank for sure.
I know my bottle gauge on my impact is off more than 50 bar. I have fill it till the gauges needle is one the word bar.
The gauges Joe uses are high quality and liquid filled witch makes more accurate
fx gauges are very very cheap and I think that's pretty crazy. Spend 2000$ on a " quality " gun and have to deal with things like that

Plus 1 with what dead eye said. Use the gauge on your tank. My FX gun gauges are way off. Plus my FX book says use the tank gauge as they say the gun gauges are not usually accurate. Strange for a gun built so well eh? . Brian

I’ve ordered 2 of the new electronic gauges from Edgunwest from what I’ve seen and read they should be the most accurate for the money
here is a Youtube video on them which shoes testing results

Trust the tank gauge. I've checked it against the fill shop's gauge and they are very close to one another. I have a new Wika gauge on my Cricket as the OEM started to leak. I think it is right with the tank gauge. The FX gauges are way off.
I have a couple of Huma gauges coming for the Impact so I will be curious to see how they compare.
I've heard good things about the Huma so thought I'd take a chance. Will report back. Should be here next week from England.

I am curious how this plays out. I just ordered a Crown and thought about these gauges. My Daystate has the information screen that comes in handy.

Ever ever trust a gauge on a rifle no matter how expensive the rifle is. The only true reading you will get is the one on your tank. Remember you are using diver air at a high PSI it can and will go badly wrong if you over fill. I have seen a rifle that was over filled and it was not a sight I ever want to see again. Electronic gauges look good and have great hype but and it’s a big but would you put yours or another’s life on the line. Dive tank gauges have been around for years and have been fully tested year in year out a cheap electronic one may look good but and it a big but it’s not realy had that much testing.

Way back when when I was in the Navy one of the jobs I did on a Sub Tender was to check and calibrate the guages that are on our submarines. Electronic gauges were not around yet. We had a set of guages that we used for calibration that were extremely accurate the reason they couldn’t be used on the boats they are too large. I know nothing about the technology in modern electronic guages. But since in the modern Navy they are being used I imagine that there are accurate ones out there. I have ordered a couple of the new Electronic gauges from Edgun and I will be working on testing them as soon as my ASTM pressure gauge arrives which has been calibrated th less than 1% variance. I probably wouldn’t trust the cheap guages either but. What I’m more concerned about is not how good the guages are out of the box but how they perform after being on a rifle for long periods, bounced around and dropped.
