TSD – Technical SafeAir Diver

During this course you will gain the necessary knowledge for planning and performing independent dives with up to three different breathing gas mixtures and up to the depth of 40 meters and time of decompression of up to 30 minutes.

As a Technical SafeAir Diver you can extend your bottom time with the help of planned decompression. For optimal and safe completion of such dives it is recommended using more than one breathing gas.
