Come on down and work with us in the rivers for a little bit. Let's see what kind of diver you are? 0 Viz, 38 degrees, 2.5 - 3.0 Knot current, working with the sense of touch only. Cleaning out water intakes or rebuilding them, lifting boats or like recently hooking up wenches to a sunken bulldozer.
Where do you learn to do this in your GUE or DIR seminar, class, lecture or whatever it is this week. Do they teach you what kind of photographs to take of the water intakes and how to do it in some of these coniditions. Or the photographs we had to take of the bulldozer...A man died on it the day before. I'm sure your "above recreational training" has taught you how to handle this type of scene.
So now you claim to be a commercial diver...... Hmmmm.... This is relevant to what???
Let's see. Zero vis, heavy current, touch contact. Sounds like my last dive on the U-853, except that I was also in 120 fsw. Are your rivers that deep?
I also didn't have surface supplied gas or u/w communications.
Regardless, its obvious that commercial work is different than any type of sport diving. I make no claim to being a commercial diver.
That said, I do see some similarities in some of the concepts. DIR emphasizes training, experience and equipment. According to some of the knowledgeable commercial divers, such as Pipedope, commercial diving also emphasizes these elements, albeit with different types of training, equipment and support that is based upon the different mission of a commercial diver.
Regardless, if you've got the cash and the equipment, I've got the time.
The fact remains that you are continuously shooting your mouth off about DIR when you've never taken a course and, therefore, have absolutely no clue what you are talking about. Your alleged commercal diving experience doesn't change that fact.
Incidentally, I don't think that DIR divers are superior merely because they are DIR. My point was that you have no way of knowing, one way or the other, and won't until you take a course so that you can offer actual comparisons that are not based on third-hand internet hearsay.
