Dean,Scary stuff here actually. Contingency planning, to my thinking, needs to account for the potential need to escape (if able) from operating depth. Off course in say, Idabel / Deepworker...etc,...the point is moot.
I'm assuming the British record as pointed out by Jay of 600', was military guys properly trained, equipped, and supported.
When I think of this, I think about the Andréa Doria, (Mt Everest of diving), which lies at some 250' if I recall. This kills someone nearly every year. If you think about it, the Doria is at a dinky depth were submersibles are concerned.
I do believe, with my level of training and prep, that I could survive escape from 150' with some degree of certainty. Beyond that, I'm not so sure.

To my thinking,once my little PSUB would pass normal safe SCUBA depths 130' or so, wellthen...I might as well be in the Abyss for all the difference it would make. Joe you bring a good question here. Just what is the max free ascent depth? Ihave qualified to 140' and have done several. This was about 1972 and have not been more than about 60' since. If memory serves the record at that time was like 400', my poor old gray matter has been malfunctioning a lot of late, so I could be way off. Dean Ackman soon proud builder and designer of RECON1
