The Extended Range course is the gateway to full on technical diving. This course will take divers beyond 40 meters, allow staged decompression, and introduce you to diving in a full technical diving system.

The Extended Range divers course can be completed as a stand alone program encompassing advanced nitrox or as a shorter, add on program for divers who have completed the Advanced Nitrox certification course. Extended Range is a prerequisite for any technical diving program in the SSI TXR Range.
