Make an informed decision in the first place about diving at this particular time. If you're stretched out like a waving flag from the hang line or anchor line, maybe this is not the time to dive. Once below and a current develops, increases, or changes direction, make a prudent decision to abort the dive. Don't delay, as every second the current is taking you further from the diveboat. Carry one or more signaling devices such as a safety sausage, horn, or whistle to assure you can be located by a boat or rescue attempt.
Drift diving uses the current for propulsion while the dive boat follows bubbles on the surface.
When drift diving from shore, make sure you have checked out the accessibility of several exit points. The sensation of hanging motionless while colorful walls covered with corals, sponges, and tropical fish pass effortlessly by your facemask appeals to many divers. But the dangers of separation and vertical currents are very real and need your constant attention. All rights reserved. Used under License.
