From the description, it's limited to about 30 ft or so, and it sounds like it's "tethered" to a buoy. If it fails, you would just do a "free ascent" to the surface. You are still breathing regulated air at depth, just like you would from a regulator.bellotech said:Interesting. ... what if it malfunctions @ 80ft depth?
Nah... I still remember how to do it just fine - the memory hasn't forgotten anything.babak said:Yeah but you should very definitely take a refresher course with a couple of hours in a pool to go over skills.
