"If you’re looking for an operator with knowledge, flexibility, and personability, look no further! Diving with Marc & Hannah was one of the best diving trips thus far - essentially a personally tailored couple days where they provided excellent guiding in and out of the water. Thanks again for the good times Marc & Hannah."

Enriched Air Nitrox Course - Need to know

Want to stay deep underwater for longer, feel less tired after a series of dives, or maybe you would like to have shorter surface intervals? When diving with nitrox we change the mix of nitrogen/oxygen in the air we breath from our tank. We reduce the % of nitrogen and increase the % of oxygen to minimise the residual nitrogen in our system after a dive. You will learn how to analyze what is in your tank, calculate what your maximum depth will be, and figure out your new extended bottom time.

This is a one day theory based SDI course but it can be combined perfectly with deeper dives at The Pit or Angelita to really emphasise the benefits of using nitrox and for you to practise the theory, you have just learnt.
