I have an FX Impact and an FX 4 stage pump. As you can see, the Impact reads about 25 bar higher than the pump. Which one do I trust?
Otherwise I'm super happy with my Impact. I'm getting 1/2" groups at 50 yards with zero tuning so far.

FX Impact manometer accurate?

Ok, if I go by the pump reading to the recommended 250 bar it looks like this. I assume this isn't too bad for it.
While I'm here, can anyone tell me if it's ok to dry fire? I've read that it's not ok and I understand why you wouldn't want to on a spring gun but I don't understand why you couldn't with a PCP, especially with air in the tank. Thanks again for the help.

No problem to dry fire on pcp's as long as there's air in it. I wouldn't shoot with less than 100 bar, velocities will drop before that point tho

A link on Impact gauges. http://www.airgunnation.com/topic/fx-impact-with-upgraded-gauges-wika-photos/
My Impact regulator gauge is 40 bar off as well.

Has anyone determined if the Crown gauges are any more accurate, and if they fit the Impact?

I really like the Impact, it has many desirable features. Looks, infinite tweaking options but if you can not trust the gauges the owner is in the DARK. This is a well known drawback with the Impact. Wika has a better option. Come on FX, fix it before you ship.

Differences in marked values between gauges is not unusual. That has never troubled me since I chrony a shot string with the gauge onthe gun and know either the exact full pressure required for the particular gun or when're fill is required. That chrony is the most essential tool for an AG shooter.

Get some of the good ones . 
aaand get a single shot tray from ernest rowe.
Also get the 26 round side shot mags.

I read somewhere that the Wika gauge was 1/8 NPT, but that they fit OK. Is that true, or just for the one that person was using? I couldn't bring myself to use the wrong thread even if it did seem to work. If they do come in the correct thread, are they really that much more accurate? How much do they cost, and does any US retail company carry the one we'd need?
At this point, I'd settle for any accurate gauge I could screw in to set my regulator, and verify the bottle pressure.
Cheers,
Rusty

Thanks for the links. I read the wika photos thread a while back, but clearly didn't pay close enough attention. Thanks for making me read it again

I just shot the rifle down to where the regulator pressure started to drop, then made my best guesstimate of the readings on both gauges. The first time the reg dropped below the max 150 indicated was 180 bottle/145 reg. The lowest I went was 150 bottle/115 reg. At every point in between the bottle was 30-35 bar higher than the reg. Either or both of these gauges is clearly off, and my bet would be both. I'm guessing the reg is reading maybe 10 high, and the bottle is reading 20-25 low.
I guess I may have to try the Wika gauges. I read that they come in chrome, which I'd prefer over gold, but I'd take most anything that's accurate. I'd still like to know if the Crown gauges are any better, and if they fit. Maybe Ernest would know that.
Thanks,
Rusty

I ordered one of these Wika manometers from Edgun West not more than an hour ago and received a shipping confirmation via USPS not more than 15 minutes later! Wish some other companies were as timely as them!

I just saw your post in another thread. I sent an email to Ernest earlier, and I'll see if he has them to sell. Buying from him is the least I could do for the great videos he's put out. If he doesn't have them, I'll be hitting edgunwest for sure.
Thanks,
Rusty

Hi Rusty,
I found out about these Wika manometers from Ernest earlier this evening. I contacted him to see if he had a manometer that would fit my Wildcat air bleeder hole and he told me he was all out of them, and that I should just contact Edgun West directly. So get em' while they're hot!
