Surface Dive

No Mask Breathing

Snorkel Ascents

Hovering

Hyperventilation

Skills Preview – Hyperventilation

What are you going to learn? You will learn and demonstrate proper hyperventilation

when skin diving. Why learn this skill?

Hyperventilation reduces the carbon dioxide in your system as since it’s carbon dioxide that stimulates you to breath you can stay down longer before you feel the urge to breathe.

Things to remember: Don’t hyperventilate excessively Take only 3 or 4 rapid breaths Rest a minute or so between dives

for a distance of at least 15 metres/50 feet underwater both as a donor and a receiver (optional skill).

Why learn this skill? It’s not likely but if you or your buddy were to run-out-air

and could not locate an alternate air source you could buddy breathe and make a safe ascent to the surface.

Things to remember: Review emergency procedures before the dive. Blow bubbles when ever the second stage is out of your

mouth. Take two breaths only and pass the regulator. Maintain a firm hold of your buddy and the regulator second

stage.
