Description
What changes when diving at altitude? Once we are no longer at sea level, the ambient pressure is lower at the beginning of the dive. This affects nitrogen saturation – so you have to take into account the altitude you are at.
In our online course, we explain the correct procedures for diving in mountain lakes. To this end, we offer you some basic considerations about traveling to higher altitudes after diving, and related to flying after diving.
Since nothing changes in the water, this course can be taken as a theory-only course.

Just finished this course and it was excellent. They have developed their own materials since SSI does not have them. They are easy to understand, thorough, and have enough depth to allow someone to dig deeper on their own if they wish. I’ll definitely take another class from them and maybe plan a dive trip to La Palma now.

This course was fantastic. There is tons of theory, charts and graphs, and “nerd” stuff; but also very practical information on setting computers correctly, driving away from a site over a mountain pass/summit, and more. My son and I are diving a mountain lake at 1,800m in less than a month and this gave us the background needed to make good planning decisions. Thanks so much Punkfish!
