TheHobster:intersting thread as I am presenting a topic to our club "Things we can learn from the Technical Diver" and trying to keep it simple. and in the 1 hour time frame; but also to show what the diver can do/purchase to do some of the same things - however, the biggest difference is the mental approach - safety, redundancy, maintenance, vigilance
I remember reading something that Tom Mount wrote (maybe in the tech diver encyclopedia), where he suggested that maybe the "tech" in "tech diver" should be thought of as standing for "technique" rather than "technical".
While, on the average, "technical divers" learn basic technique to a higher level than many "recreational divers", that higher level of technique applies very well to shallower and non-overhead diving also. So, a shallow, non-overhead diver might do just fine without some "technical" aspects, but the technique would still serve them pretty well. Once we start looking at some specific techniques that "technical divers" commonly learn and apply, it becomes pretty clear how those techniques can apply to and improve any diving.
