Tec 40 course introduces divers to limited decompression diving within accepted recreational depth limits. Therefore, to accommodate divers interested in very limited tec diving, the Tec 40 equipment requirements are only a bit beyond those of the standard recreational kit. Candidates interested in continuing their tec education later can do the course in ful tec rig. Certified Tec 40 divers are allowed to make decompression dives to a maximum depth of 40 meters/130 feet with no more than 10 minutes of decompression.

Tec 45 course provides a transitional qualification while continuing to develop as a technical diver. This diver is qualified to make limited technical decompression dives using the equipment and the procedures used at the Tec Deep Diver level. However, qualifications are narrow, reflecting comparatively limited training and experience. Certified Tec 45 divers are qualified to make multistop decompression dives that employ EANx and oxygen for accelerated decompression.

Tec Trimix Diver course is intended to extend the depth range of technical divers already trained and qualified to use air, enriched air and oxygen for technical decompression dives beyond 50 metres. Diving with trimix is the outer edge of tec diving – the maximum depth for using this technology has yet to be defined. This course is for Tec 50 or Tec Trimix 65 (or those holding a qualifying certification from another training organization). The course extends your depth range capabilities by training you to use trimix (a blend of helium, oxygen and nitrogen).
