Whether it’s the reef, an anchor line, the bottom or a wreck, make sure you always have a visual reference. If you have lost it, search for a maximum of one minute and then abort your dive. Because even if you don’t realize it, there is almost always a current at sea and that current can distract you so far from the dive site that the crew can hardly find you. So don’t do anything crazy, abort your dive and ask them to drop you back at the reef so you can continue enjoying your dive in safety.
