Thalassamania:I'm not talking about DIR either, note the lower case doing it right<G>. You want to empty the China Room on the Doria? Send in a small ROV or Put a lock out sub down on her and go out saturated and on a hose, tended by another diver who also has coms at the entrance and each bend. That's what I mean by doing it right, applying the correct technology and procedures to the task at hand.
It seems to me that your focus is much more on the professional/ scientific diver. I understand what you are saying, and in that context, I agree with you. However, the vast majority of us don't fit in that role, and don't have any desire to. So let me ask you, what is wrong with me visiting the china room on the Doria on my lowly OC doubles, utilizing scooters and mixed gas just for the hell of it? Just because for *me* it's fun and how I choose to spend my excess income? You seem to imply that we should all look at pretty fishes in 20' of water unless we are SCIENTISTS. Frankly, I find your attitude condescending at best, and I fail to understand why you post on a board about SCUBA as a recreational activity, when you clearly don't see it as one.
