Trimix Diver

This program is designed for those individuals already involved in deep diving activities but wish to develop the skills, ability and knowledge to enable safe diving in the trimix depth range. It includes extensive dive planning workshops covering all bailout scenarios, run time management and choice of gases. The diver’s skills are developed to the highest level to promote self sufficiency and safety whilst maintaining the ability to operate within a team.

The program includes academic lectures, confined water skills development and open water dives. Gas switching computers can be used (and are recommended) but IANTD tables must be used as a backup.
