Most of my deep dives were 130-140 with requisite safety stops where we fed fish sea urchins while we waited. Tried 170 once and did not like the buzz I got while down there. No way would I consider doing 196. I suspect someone is going to get burned big time on this one for negligence.The US Navy considers a dive below 180 feet as being 'dangerous'.
A dive to 196 feet on a single tank give you an extremely limited amount of bottom time before the diver must start to return to the surface while taking mandatory recompression stops.
I'll await hearing more--like: How experienced were the divers? Were they diving with more than one tank? Were they diving on 'mixed gases'? What was the plan to navigate in and out? What was their "Plan B" plan if something went wrong? Too many unanswered questions at this point. 'Rapture of the deep' is one possibility.
