But a fluctuation of 100 psi or so at full is not uncommon.

Interesting. I'll have to check my gauge against a few other gauges with tanks at various pressures. I hadn't really thought about it being a percentage off, but had been thinking it was a constant 200 lbs off. On a side note, and to probably spark some follow on debate....I just can't bring myself to go with an integrated air computer and NOT back it up with analog. I have the Aeris Atmos II wrist computer (from ST) and I back that up with Tusa analog gauges (from ST). So, Larry I saw the thread, but I'm still pretty happy with my Atmos II. I think when I need to replace the computer, I'll get a hoseless wrist mount.....and keep the analog on the HP hose. Call me overly conservative and reluctant if you wish, but I like the redundency.
I have only really paid much attention when I first turn on my tank to dive. The gauge reads about 200 psi less than the shop's analog gauge that is on the refill system and the stand alone tank pressure checker.
I'll also grab a few rental regs next time and cross check them all just to see where I stand.
By the way when are Larry and Joe going to put that new Scuba Shop in San Antonio?
Thanks everyone for the input so far.
