Impact X and the MK-2

Jump to latest Follow Reply
... better gauges, but not as good as wika gauge. People with mk2 still replaced the new fx mk2 gauges with wika...

One question, what is the accuracy of such "fancy" pressure gauges? I mean gauges delivered with Mk2. And what is the accuracy of WIKA gauges? 4%? 2,5%? 1,6%? 1%? 0,6%? Everybody's chasing the best pressure gauge, but nobody knows what is he buying. I tried to get the accuracy of gauges provided to Mk2, but not succeeded...

I'd say all gauges are 2,5%, not better. They are just overpriced :D

Yeah :D Within industrial pressure gauges, this accuracy information is written directly on the dial, but whatever airgun gauge I saw, such information is not there... But it costs tens or hundreds bugs :D (standard 2,5% gauge costs cca 7-8 bugs)

That bugs me

Don’t forget the mk2 comes in 35cal. 
and i am not 100% sure when or witch impact has it but the valve Seat is now in one peice so no more broken valve seats

There is no 35 cal Impact. That is a myth like the 50 cal hammer. They announced the 35 cal beginning of the year and released the mk2, but not the 35 cal. Keep dreaming and maybe one day they will finally release the 35 cal impact and 50 cal hammer.

From a practical standpoint it doeas not matter much if the gauge is 10 bar wrong. You can usually compare the gauge, to the one on the fill kit (which usually are bigger an more presice) the first time you fill the gun. Or use a chronograph to read the pressure when the gun falls of the reg, and take a note. What is more important is that the gauge read the same every time. If the gauge get stuck, and suddenly drops 10-30 bar, then it is a more useless gauge. Some gauges are like the old speedometers on cars, where they are right at a given pressure, but more wrong the higher you go. If you are lucky you may find one which read right at the most common reg pressure ranges, but may be 10-20 bar off at higher pressures. 

I think Robert Lane explains well why gauges on most airguns can be pretty unpresice https://www.youtube.com/watch?v=qdoY-4EtYd0&t=51s.

Basically if you gonna have a precise analog gauge, you need to have a bigger one (like the one on the fillkit), than the small ones which are fitted on most guns. Most small gauges have a simple design, and is not meant to be very precise. If you gonna keep the gauge small and precise, the digital gauges like the Edgun gauge might be better, as they do not use a simple brass coil to read pressure.
