CALI68:I wouldn't use it for tech diving either. If I was going "tech" deep I would definately go with a spare Reg. but I like it alot for the recreational diving I do. It's as good at depth as any reg I've ever tried (my main Reg is a Aqua Lung Legend LX Supreme) All the obvious functions are great. I've done safety practices with it and I find it to be pretty simple to use in those situations as well. I may be wrong but I think they make a titanium version that's for Tech (Nitrox) use but don't quote me...call Atomic.
Titanium isn't a good material for high FO2 gasses so I wouldn't consider a reg made of titanium a "tech" reg.
If there's any advantage at all it would probably be resistance to corrosion but mostly I think it's just expensive BS.
