IANTD Advanced Nitrox/Recreational Trimix Diver

The IANTD Advanced Nitrox program is designed to extend the diver's knowledge of the use of Nitrox (EANx) mixes. It introduces the core skills from the technical diver training programs including the use of twin sets with central isolation manifolds and decompression skills and procedures.

You’ll get the opportunity to practice skills for controlled/timed ascents, handling stage cylinders (removal and replacement), gas switches, gas management, shutdowns and out of gas drills, SMB deployment, as well as practicing streamlining and propulsion techniques, reviewing kit set up and configuration and an introduction to decompression diving. The course qualifies divers to dive to a maximum depth of 42m, using decompression mixes of up to 100% oxygen for up to 15 minutes.

The IANTD Advanced Recreational Trimix course covers everything in the Advanced Nitrox course and can be taken as an alternative to the IANTD Advanced Nitrox course for divers who wish to take advantage of the reduced narcosis and associated safety benefits that helium based bottom mixes offer. In addition to the Advanced Nitrox syllabus, this course also covers the use of helium mixes that maintain an Equivalent Narcotic Depth of 24m or less, with a focus on the use of two standard recreational trimix bottom mixes - 32/15 and 28/25 - to a maximum depth of 48m.
