I am looking for a small and cheap analog gauge console (pressure and depth) to be used only as a back up for an Aeris Elite. I had the Elite fail on me one time and thankfully, it was just at a pool while taking a class. I figure if I had a back up, I could just switch out the transmitter on the first stage with the console and not worry about missing a dive. I would like something small but not so small that it would be difficult to see. Also something luminescent so it can bee seen in low light.
