Who this course is for:

Individuals that wish to learn the “How to’s” for two different types of snorkelling, and allow them to be more comfortable in the water.

The two types of snorkelling are:

  • Snorkelling

    – Snorkelling is the use of mask fins and snorkel to primarily swim on the surface while being able to keep your face in the water without having to lift your head to breathe. Periodically you may dive below the surface for a short period of time to exam something closer

  • Free diving

    – Free diving also uses mask fins and snorkel, but the primary focus to perform extended breath-hold dives below the surface for activities such as spear-fishing or some other type of game collecting, or pushing one’s depth or time limits

Course prerequisites:

  • Minimum age 18, 4 with parental consent
