Tec 1
You might have heard of this program referred to in a few different ways depending on the agency you are used to. Tec 1(GUE), Decompression Diver(NAUI), Advanced Nitrox/Stage Decompression (TDI) or Tec 45(PADI). Are you looking to extend your dive time? Maybe you’re a scientific diver or photographer looking to stay in the water a little longer? The Tec 1 program qualifies divers to use enriched air nitrox from EAN 21 through EAN 100 percent during decompression diving. With a maximum operating depth of 45 metres/150 feet, this course is your first step beyond the normal sport diving limits. This can be considered the foundation of your technical diving career.The Tec 1 course is the foundation of all other technical courses. After this course and some additional experience, the stage has been set for you to move onto additional technical levels.

Trimix
Are you looking to expand your depth range? Do you want to reduce narcosis during deep dives? The Trimix Diver Course could be your next step! As your motivation to explore progresses, you will find that you may want to go deeper to dive that wreck that is part of history or that cave system that you have read so much about. One of the major limiting factors of going deeper is narcosis; 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 Instructor will teach you how to plan and execute dives utilizing as little as 18 percent oxygen and diving to maximum depth of 60 metres/200 feet with a blend of helium appropriate for the planned depth.
