Anyway, you are in the wreck and you see your buddy get that wild look in their eye. You see this because you're paying attention. You see the look and you stop him, you look him in the eye, you control the situation, you stop, think, breath, and then act. You probably exit the wreck. You never let it go to panic.
When wreck diving and also often in other situations I am diving solo. Probably with someone also doing that only a meter from me, but solo anyway for both.
Both of us would not like the other to act on our behalf in any way before we ask for it or really panic.
With most groups I dive with I have more dives than the instructors or equal to them.
Most of the time I go as a one person buddy team then, too, or have a buddy or two I have to watch constantly
Nobody looks after me at all. If someone does, it is an overeager instructor who panics when he sees me remove a tank.
And if I ever drop my helmet I will have to catch it myself.
Had a dive recently where I was filming from a 'just above ground position' upward.
Switched regulators, but the exhaust diaphragm was stuck open.
Gulped down a few regs full of water and went down.
The group videoed me from several angles throwing up the biggest unnecessary cloud I have for a year and camly moved on while I sorted regs and fixed the problem catching up.
They only found out about my problem later on facebook when I posted the picture to talk about it. We had other things to talk about in debriefing.
