This course will prepare you to use breathing gasses containing helium for dives with depths to 300 fsw that require staged decompression.

This course is even more extensive and demanding than Extended Range, although you may find it more
enjoyable to dive with a clear head beyond depths of 180 fsw. Comfortable in water with drysuit, double and stage bottles.

Prerequisite: Normoxic Trimix  & 100 logged dives of which 25 must be deeper than 100 fsw

Cost: $650.00
Combined Cost: Normoxic and Advanced Trimix $1250.00
