IANTD Rebreather Courses

Rebreather Trimix Diver

This IANTD Rebreather Trimix diver Program is designed for those individuals already involved in deep diving activities but is not intended to be used as an enticement to divers who are content to remain in Sport or EANx diving limits. Trimix affords a safer means for deep water exploration for divers who dive deep or perform with a clear head at depth. The IANTD CCR Trimix Diver Program requires the diver to be self-sufficient/reliant.

The knowledge and skills taught in this program are more than adequate to qualify divers to perform Trimix Dives outside of training up to 100 m.
