Upon certification, you will be qualified to dive to 60msw using diluent and bailout mixes containing helium.

You should hold an Advanced Nitrox or Advanced Recreational Trimix Diver qualification, or equivalent, with over 100 logged dives. At least 30 of these dives must be deeper than 27msw. You will also need to be a qualified diver on your chosen rebreather, along with having at least 20 dives and 25hours logged. However, we would always recommend that you aim closer to 50hours before considering attending a CCR Normoxic Trimix Diver course. You should be comfortable in the water and have competence completing basic diving skills (mask skills, DSMB deployment etc.) mid-water while maintaining neutral buoyancy.

You will be provided with the IANTD CCR Normoxic Trimix Diver Student Kit, including the IANTD Exploration and Mixed Gas Encyclopaedia – The Tao of Survival Underwater and tables for dive planning. In addition you will need your chosen model of Closed Circuit Rebreather, along with a primary buoyancy device, dive computer / depth timer, basic dive kit (inc. SMB & Reel / Spool and a slate or notebook) and two bailout / stage cylinders with regulators (all in oxygen service). We recommend aluminium stage cylinders.

This price includes the training and materials outlined above. Certification costs are also included (providing certification criteria are met).
