Sharing a dive computer....

[Sat Diver]

....actually works pretty well based on empirical evidence over 20 dives my wife and I conducted. Wearing identical dive computers we surfaced from each of these dives with identical time remaining (within the same minute), identical nitrogen loads. My conclusion is that, if needed, we could run a single computer without problems.

Get surface supply and a dive supervisor and you don't need even one computer. It's the best option
No tanks needed and no gas management. Never worry about you SAC ever again!!!

I know someone who was bent because the supervisor made a mistake on his deco calculation!!!
Developed severe joint pain in the evening.
Complete recovery after spending sometime in the chamber.

I was actually trying to be funny. I personally know of people being killed by mistakes made by supervisors.
