Lesson five: No Mask Swim

Course Complete

Skills Overview

If you were to lose your mask and not be able to locate it or retrieve it, you would have to end the dive without it. The no mask swim allows you to practice and demonstrate that you could.

No Mask Swim
  • You may close your eyes if you have contacts, though you would keep them open if you really had to ascend without your mask.
  • Otherwise, keep your eyes open because you can see enough to be useful.
  • Swim with your buddy at least 15 metres/50 feet. Control your buoyancy, equalize your ears, etc. as you normally would. Your buddy will guide you (especially if you have your eyes closed).
  • Concentrate on breathing through your mouth. Exhale through your nose if the water tickles it a bit.
  • After the swim, replace your mask and clear it.
