Includes 2 charter trips

The SSI Extended Range course is part 2 of 3 from the SSI XR Courses (non Trimix). 

The course focuses on giving you the skills needed to safely conduct an open circuit technical decompression dive to 45m using a single decompression gas of upto 100% O2 for accelerated decompression with your team.

Successful candidates will not only be qualified to conduct decompression dives to a max depth of 45m, but more importantly, the course builds on skills learnt on the Foundations and XR Nitrox courses, so you will be comfortable using twins with different gas mixes in your stage cylinders.
