Are there any shock pumps out there that have something like a quick release connector rather than the standard screw on kind? I've been experimenting with the 2 I have at home and when checking the shock pressure with a calibrated pressure gauge I seem to lose between 20-40 psi each time I remove it. Which is a bit of an arse

Someone on the classifieds (Not me!) is selling a Scott one which somehow avoids this.

Must be the ultimate shock pump out there!

You don't lose pressure when you disconnect a shock pump, it has a non return valve in the.......valve.
The air escaping is from the tube/pump.
When you connect a pressure gauge you will lose a little air as it charges the device so will read less than what it read when you disconnected the pump...
That's my take, but happy to be proven wrong by a shock pump genius.
I'm with kayak on this.. The perceived pressure drop is the shock filling the pump.
^ This is the correct answer 😉
Yep
Except on some really bad shock pumps anyway. But every one that's fit for purpose is lossless
