No! You just need to pass a simple swim test at the beginning of the course. The test is a 200-yard swim without fins and mask, untimed. Then a 10-minute treading water test, where you just need to keep your head above water.
If you don’t think you can pass the test, or want to become a better swimmer, check out our swim school! We have programs for all ages or you can sign up for private lessons and focus on this scuba test.
