Timely post for me because I am ALSO going on a liveaboard soon (I leave tonight!) and have no backup computer. Mea culpa. I guess I will need to, for this trip, roll the dice and hope that 1) mine doesn't stop working or 2) I can rent a backup from the LOB operator.
For future reference, my dive computer is a hose-mounted air-integrated one. What type of backup should I purchase? If I buy a simple wrist-mounted one, and my primary fails, I won't have any way of determining gas remaining, unless the backup has a transmitter, correct? Or do I purchase an inexpensive SPG to go along with an inexpensive wrist mount?
My wife, who is not diving with me on this trip, also has a hose-mounted air-integrated DC. Could I bring that along in the event mine fails? But then I would have to dive with 2 hose mounted DCs simultaneously so that both DCs have the same nitrogen loading. How would I do that?
Thanks.
