The SSI EXTENDED RANGE (XR) course line was created to properly prepare divers to push their limits—both in terms of dive time and depth. Proper training and preparation allow divers to safely exceed 40 meters in depth and extend their dive time through properly planned and executed decompression stops.
The Extended Range course is the first major step on your journey to truly deep dives.
In this course, the main emphasis is on improving swimming techniques with a twin-tank setup, procedures specific to technical diving, and learning how to plan and conduct dives requiring decompression.
After completing the course, you are certified to dive with someone who has the same or higher certification:
- using mixtures up to 100% oxygen for decompression
- with a maximum depth limit of 45 m
- with a maximum decompression time of 25 minutes
