While I 100% agree, I was to blame, as I stated. I'm the one who rigged all my gear. I will take advice on double strapping my tank in. I think my whole point, is no matter what, even with a dive partner, you are solo diving. No, we did not have a dive plan in place, other then I'll follow you.
I agree with DIVEMASTERDAVE above, but sometimes it is not ideal. I want to take my time and take pictures, but my dive buddy wants to hurry from site to site, not ideal at all. All you can do, if that's your only choice, is ask look back once in a while. I was with a guy that I only met twice and he had those big open fins that could outpace me 2-1. So, choice was not dive at all, or rely that I could save myself if needed, and it happened. I'll admit I was born in the water and not prone to panic, a new diver might have met a fate. I practiced several times of taking all my gear off under water in a shallow pool, to learn there is always a way out. But, a new strapping system is coming
Thanks all.
Edit, the only reason I did not remove my gear to fix the tank at depth, was I worried about having my wetsuit on, I would have floated above my gear as the weights are in the BC. Maybe I could have removed the weight pockets, held onto them somehow and adjusted the situation. I thought about it, and felt the risk was far greater then doing my one hand thing. Maybe I am missing something?
