The first condition is, you need to buy a Spare Air device. Very few good divers enter the water now a day without a Spare Air or even TWO.
Redundancy is the answer, just ask any folks who dives DIR, and they would highly recommend the Spare Air. DannyDon is an ardent supporter of Spare Air, and he is a highly respected member of scubaboard.
