Appears I'm on a roll tonight with questions that probably have obvious answers. This one has been bugging me since diving sidemount for the first time with my wife two weeks ago. She was diving a single tank backmount and I of course had two tanks sidemounted on my Hollis SMS 50. First dive really wasn't an issue as far as signalling air remaining as I always had air! Second dive however, I started the dive with about 2300 psi in each tank and once I got to 1500 psi in each it dawn on me that we hadn't discussed how I would signal my remaining air. I decided to treat it as if I was diving a single tank and signaled the pressure for the higher tank. Not sure though if that was the correct approach though.
So is there an agreed upon way of dealing with this situation? I'm curious because when we hit the all-inclusive resorts that have the mandatory DM "follow me" dives you have to signal pressure once you reach 1500 psi and then the whole group ascends once the first diver hits 1000 psi. I don't want to be the cause of the whole group coming up to early on the 2nd dive since 1000psi in each of my tanks would really be 1500 single tank equivalant. Or am I doing the math wrong?
Thanks,
Paul
