There are many high mountain lakes and most have a very good visibility. What do you need to know to dive them safely?
The answer is the SSI Specialty Altitude Diving.
If you dive in a body of water 300 to 3000 meters above sea level, you call this Altitude Diving.
Most algorithms have been designed to plan dives up to 300 meters. During your Altitude Diving program, you will find everything you need to safely plan dives at a higher altitude.
The primary goal of any SSI Specialty course is to teach you important skills in a fun environment. All courses are taught using home study, short academic sessions, and in-water training.
