Exploration Diver Level 1 Rebreather

Rebreather upgrade with trimix and decompression gases.

The ISE Rebreather Exploration Diver Level 1 course is structured to prepare divers for the rigors of exploration diving, and to familiarize them with the use of different types of breathing and decompression mixtures. The training focuses on expanding the skills learnt in the ISE Basic of Exploration, and is designed to build the necessary and essential skills required for safe and successful exploration trimix diving. This will include problem identification and resolution, and building the capacity progressively for more challenging dives.
In this course, students will be trained in: a) the use of double tanks and in the potential failure problems associated with them; b) the use of Trimix and Nitrox c) the use of Helium to minimize narcosis; and d) the applications of single decompression cylinder diving with respect to decompression procedures. The exploration diver level 1 class will focus on Nitrox and Trimix, for dives in the 50 meter depth range, and provides an excellent foundation on which divers can build their diving experience and prepare for further ISE programs.

Duration

This exploration diver level 1 class will be conducted over a duration of 5 days, and involves at least 5 dives.
