TDI Trimix 75m

Are you looking to expand your depth range? One of the major limiting factors of going deeper is narcosis; TDI’s Trimix Diver course shows how to minimize the effects of narcosis by adding helium to offset the nitrogen in your breathing gas. While taking the Trimix Diver course your TDI Instructor will teach you how to plan and execute dives utilizing as little as 16 percent oxygen and diving to maximum depth of 75 meters/250 feet with a blend of helium appropriate for the planned depth.
