Again a specialist application which requires specialist solutions.
It’s team bailout at 100m. You can’t carry enough yourself. Planning is complex and may include safety divers. Overhead diving would include staged bailout and deco cylinders. Deep wrecks would be team orders on a 'must return to shot' with lazy shot + trapeze.
A 100m/330' dive is not a run of the mill dive, very few people have ever been that deep.
BTW using 17 litre steel cylinders would really screw your buoyancy on CCR especially if they’re removable.
For a larf, how many cylinders would one person need for bailout on a 100m/330' dive with a sensible bottom time of, say, 30 mins?
4 x ali80s? That’s without mitigating a CO2 hit.
