Technical Diving – Optimal Gas Mixes

Knowledge of optimal gas mix selection is critical to the technical diver. The graph below simply correlates bottom depth against a desired END, and is consistent with the tech community standard of 1.4PP02 for the working phase of the dive.

The chart does not substitute for accurate technical dive planning utilizing appropriate decompression software.

Scuba Tech Philippines HIGHLY RECOMMENDS to never dive with an END over 40m if entering an overhead environment. Environmental conditions and other factors; such as cold water or exertion, should be accounted for when determining a suitable END. Always dive within personal limits, ability and your training.
