First Course using a Helium Mixture – Dives are to 200’ using 2 stage bottles.
Graduates can make dives requiring long decompression stops and needing expedition quality contingency plans. They are comfortable making advanced equipment selection and know-how to configure and manage additional gear to function well on long dives in local conditions. This gear will include two sling/stage cylinders containing decompression gases. They also fully understand water behaviors dictated by the use of helium in breathing mixes; are competent in using complex gas management calculations and have the ability to create, manage and modify complex decompression schedules and apply them as appropriate to the dive conditions. Graduates should also be familiar with the correct procedures for using a helium/oxygen analyzer to test mixes.
This is a two-day class and consists of 4 dives.
