Train to independently plan and conduct two-gas switch, multiple stop decompression dives using two-stage decompression gases to depths of 50 meters when using Air or 60 meters when using Normoxic Trimix (min 18% Oxygen content). Complete the programme wearing a full Extended Range total diving system.
This is the pinnacle of technical diving. There are two pathways; one takes you to 80 meters and the other to 100 meters using the same full Extended Range total diving system you mastered in previous programs. However, you will now use a minimum of three stages for decompression and travel gases.
Train to independently plan and conduct limited decompression (15 minutes of back gas decompression) dives to depths of 40 meters using nitrox mixtures of up to 50%. The program can be completed wearing your standard total diving system, a large cylinder with H or Y valve or even a full twinset.
This program prepares you for limited penetration into wreck overhead environments. You will learn overhead buoyancy and propulsion skills along with line laying and light usage. The program can be completed wearing a single cylinder with either a pony cylinder or H/Y valve or a technical total diving system.
As with wreck, this program prepares you for limited penetration into the cavern zone. You will learn similar skills to wreck with additional lost line and lost teammate procedures. The program can be completed wearing a single cylinder with either a pony cylinder or H/Y valve or a full technical diving system.
