That's the way I see it. If you are going to the expense of having two dive computers that you are diving in computer mode, why not dive with both of them? Esp. if you are traveling to some exotic destination or on a liveaboard where you wouldn't want to have to sit out 24 hours while everyone else is doing four or five dives a day. Not much value to have the "backup" on the boat instead of tracking your N2 loading.I think the best way then would be to dive two computers so that one is the back up to the other. That way both computers a reading same dive profile exactly and backs up the other in case of failure.
The other option is to do all the dives with tables or whatever and have the computer back that up. Not everyone likes that idea, esp. if it means less bottom time compared to a buddy "flying" a computer. YMMV.
(We'll leave the "Is flying your computer to the NDL a good idea?" discussion to another thread, but I see the "Is flying your computer to the NDL, then transitioning to tables a good idea?" discussion has been covered pretty well. )
That's what I do. The brass and glass SPGs are pretty durable actually. Tie a bolt snap at the end of the hose near the pressure gauge and clip it off to the d-ring on your left hip, and you are streamlined and free of the danglies. What's not to love?Now what to do with the analog depth gauge and bottom timer? Having just the SPG at the end of the HP hose sounds very tempting at this point. Any thoughts?
