The Refresher Dive (also known as a Scuba Review) is a dive in a pool or at a local reef with a dive professional to renew any skills and/or knowledge that you may have forgotten, or you’re a bit rusty. If done in the pool, the dive will focus solely on your skills, including good buoyancy control. But if done in the sea, you get to spend some time swimming around the reef looking at any marine life. It’s normally necessary to do a Refresher Dive if you haven’t dived in more than one year and plan to go out into the open ocean on a ‘Fun Diving’ trip with others. Some dive centres allow your no-dive period to be up to two years with no need for a refresher.
