Looking at slowly moving my way up the chain to dabble in tech diving. I'm getting a backplate and wing setup for myself this holiday to replace my jacket BCD. I was looking at the SSI course for extended range (starting off with a single wing, but also looking at getting a twin wing). SSI offers 2 extended range courses, one on air and one on Nitrox. I've got my normal Nitrox cert already, along with my deep, but my questions is would taking the normal extended range course make sense since I already have the Nixtrox cert, or are taking the extended range classes really worth it?
