SSI XR Extended Range Nitrox

The SSI Extended Range Nitrox course is where you transition from recreational scuba diving to technical diving. It enables you to conduct dives to a maximum depth of 40 metres, incurring up to 15 minutes of accumulated decompression time, using a single decompression cylinder of up to 100% oxygen to accelerate your decompression.

This course is not a pre-requisite for the next level, SSI Extended Range. If you want to extend your range and decompression time you can enrol directly in the SSI Extended Range course which enables you to dive to 45m with a single decompression cylinder.

The course focuses on the technical dive skills needed, the use of open circuit technical dive equipment, the importance of team skills and dive planning.

Successful candidates will not only be qualified to conduct decompression dives to a max depth of 40m, but more importantly, the course builds on skills learnt on the Intro to Tech course, so you will be comfortable using twins with different gas mixes in your stage cylinder.
