This program trains divers for depths between 100 fsw (30 msw) and up to 170 fsw (51 msw) using custom blend breathing gas mixtures. It covers the limits of EANx mixtures and the use of EANx and oxygen for decompression, equipping divers with the skills to safely conduct dives up to 170 fsw (51 msw).
Dives must not exceed 170 fsw (51 msw).
