Merc86:Yeah, that helped alot. Can you link me to the Atom so I can see what it looks like? I am not that familiar with these units so sorry if my questions seem dumb. Do you use the SPG with a wrist mount? How does it work? Doesnt the Atom wrist mount give you a psi reading?
Well the Atom is eve more money the rest of the ones suggested above, very nice unit but a bit more pricey. The Atom is also air integrated, it has a small transmitter on the first stage that displays the psi/bar remaining on the wrist unit.
The other way to do it is to have an SPG as well (if your computer is not ai), the pressure gauge is not on your wrist, rather on a hose clipped off to your side, the computer is the only thing that is on your wrist. You still check both on a regular basis, but the computer that is on your wrist has the depth, NDL limits, time etc. those change more then the gases left in your tank.
