The SSI Extended Range program qualifies you to dive to a depth of 45 meters / 145 feet using nitrox mixtures of up to 100%. The program can be completed wearing a complete Extended Range Total Diving System, appropriate for single gas switch, accelerated decompression diving

The XR EXTENDED RANGE / TRIMIX COURSE offers you just this. Due to the reduced fraction of nitrogen in your breathing gas, your body will be less work and the desaturation times will be reduced.

In this program you will learn all the rules that must be observed, when you planning and implement a decompression dive.

This provides the divers new ways without changing existing techniques and habits completely. The XR EXTENDED RANGE / TRIMIX training perfected your skills and build on your existing knowledge logically. During the training you will be using multiple gases for diving, use new equipment and safely apply decompression. This is the opportunity to discover new things and to develop further.

This program qualifies you to dive to 45 meters using nitrox and 25 minutes of accelerated decompression using a one stage decompression gas. The program can only be completed wearing a technical total diving system.

As with Extended Range, the Trimix course allows you to dive to 45 meters and 25 minutes of accelerated decompression time using one stage decompression gas. In addition to using nitrox, you will be qualified to use Trimix with a minimum oxygen content of 21%. The Trimix program is specifically designed to reduce nitrogen narcosis in the extended range diver.
