I'm diving NJ this summer and redundancy is mandatory. The last time I rented the tank + reg, the reg lacked an SPG and the reg looked pretty beat up. I didn't think much of it at the time (checked pressure at the dive shop), but really lost confidence in the setup.
I'm planning to move to doubles eventually so I recently bought a doubles reg set, and configured one to be used on my main single tank, and the other to be used on the pony until I've had some doubles training. I got a button SPG for the pony reg, but now that it's in my hand I'm not sure how readable it'll be at depth.
But then I realized that I have an old but working Mares Puck AI computer... the hose is longer than I'd need, but I think I can wrap and bungie it to the tank. That in theory would give me a 2nd backup computer too. Or is this just overkill?
