Madiera this Saturday

[ScubaDiveandTravel]

Dan,

Doubles are not required, but a redundant air source is definitely protocal in this situation. This could mean a pony bottle or doubles. I have been guilty of many solo dives on the madiera with a single 80, but I don't believe it is the safest system. I now choose to use redundancy every time I dive, with the exception of easy splashes in the tropics. I have a set of twin 50's with an isolator that I use now for local diving, and it's awesome. I have complete redundancy, and doubles are far more stable than singles. I just picked up 3 more sets if you would like to try them. They weight little more than a single with weights in your BC.
