Tech 2

The Technical Diver 2 is the second class structured to prepare divers for the rigors of Technical (decompression) diving and to familiarize them with the use of two different Helitrox breathing gases (21/35 or 25/25), use of two different decompression mixtures (Nitrox 50 or 100% O2) and the use of a stage bottle to conduct two technical dives in a day .

Tech 2 training focuses on critical skills in the bottom failures with a stage and the mid water cultivating, integrating, and ultimately testing the divers blue water skills and their ability to deal with failures not only on the bottom but also during the accent and gas switch – skills which are essential for safe technical diving. This critical training will include problem identification and resolution, and building the capacity for progressively more challenging diving.

Students will continue to use double tanks/cylinders and a single stage bottle and the potential failure problems associated with them. You will also use a deco bottle of Nitrox 50 for accelerated and “on the fly” decompression and will take advantage of the use of Helium to minimize narcosis, and the application and benefit of single decompression stage diving will be thoroughly explored.

The class will focus on Helitrox as flexible and beneficial breathing gas for dives to 160’/48m while using a single decompression gas such as Nitrox 50 for both accelerated decompression and safe rock bottom planning.
