Yesterday I dived solo in a lake that is 8 feet deep at its deepest point. It's nearby and I wanted to get wet.
Planning my dive, I determined that immediate access to the surface during all phases of the dive obviated the need for redundancy of scuba equipment.
I've used pony tanks and back-mounted doubles for slightly deeper solo dives, to about 25', but in reality that's as much about training and familiarization as safety. I've thought about using an H-valve setup.
When do you believe a solo dive requires redundant air to be safe? At what thresholds do you believe that progressively more capable redundancy (H valves offering the least and doubles offering the most capable redundancy, with ponies somewhere in between by most people's reckoning) becomes necessary?
