I recently purchased a Maverick that came with the Wika guages. It was set to and read 125 on the regulator gauge.
That back gauge is so tiny I could barely read it and installed a Sekhmet gauge this morning. It reads 114 bar.
The rifle shoots exactly the same with both. Are Wika gauges that far off on a regular basis?
I'm assuming, maybe incorrectly, that the Sekhmet is more likely to be the correct one.
 
Finally...a properly...designed gauge for PCP guns !
Sekhmet has designed a 400 bar pressure gauge.

I learned a very long time ago, that..."quality"...test equipment, in this case pressure gauges, the first and last 10% of the gauge's scale is NOT...to be used for an accurate value.

But here we are in the 2020's and everyone...in PCP shooting is humming along blindly and using gauges at their higher limit and expecting perfect pressure values !?!?
Example, a 300bar max. pressure gauge, is expected to be 100% accurate at...300bar. Or a 250 bar gauge is expected to be 100% accurate at...250bar..! What the hell, the good folks that make these "precision" instruments...(!) torque wrenches, pressure and vacuum gauges, transducers, even micrometers,
many better test equipment products have within their instructions, (paraphrasing) "do not use the first or last 10% of the scale as accurate".

So yeah...good for Sekhmet, thanks guys.

The Edgun EDMU uses the Metallux gauge that has a 400Bar range as far as I can see

I'm not sure what the range is for the Sekhmet. I'm using it for the rear gauge and that amp is set for 115 bar.
