air gauge

I dive AI computer only. Losing the transmitter means the dive is over, but it's not critical (you were watching your air anyway and have a good idea of how much you use?). One less hose to have dangling.

I'm not sure about the hesitancy to have an SPG even when using AI. We were all trained with them and should be used to them in our configuration. In the general scheme of scuba gear they cost nothing. I use an AI transmitter but will not dive without a backup SPG. It's not cumbersome, and I'll look at it maybe once or twice just to confirm all is well with the AI. As posted earlier, "One is none and two is one". Redundancy rules!

Maybe you're ending the dive and going up. That doesn't mean everyone in that situation is going up.

Basic scuba forum mi amigo.

Newer divers should go up. They likely don't have their sac rate down or ingrained to time and depth. You and I, probably staying down and finishing our dive. I've done dives recently without any pressure readings because I left my perdix at home. I borrowed a buddies Garmon to use for depth and time and went about my business. A known dive site with known sac and repeated plan. Pony as a backup and off I went. I still have tanks with J-valves and handles though they don't leave my garage much anymore. But again, this is a basic forum.

Well I need something to secure my console to the first stage

Just spent a solo dive repeatedly dismissing a low transmitter battery warning. But I dive with a little SPG, so wasn’t concerned. I think about removing it sometimes; since the only time I look at it is when I turn my tank on. But It’s pretty compact; so it still comes along for the ride.

For you guys not bothering with an spg, how does it work for your pre dive checks when you would normally breathe from your regs while looking at needle?
I'm just about to setup my Tx tomorrow and won't have an analogue

I have a miniSPG in the HP port not being used for the transmitter. The miniSPG is on the same side as the thank valve, so is easy to see if the tank is full or not. Breathing from the reg as a check works fine with the AI, just give it a few seconds.

I'm not concerned about the "barely on" scenario. I just open fully and rely on decades of successful ongoing training. I also position the tank so I can reach my valve if needed (e.g., deck hand turned it off by mistake). Descending while looking at my buddy is standard practice.

IMHO, the bigger danger is splashing with it off, which will be caught with the pre-splash breathing.
