(1) Let's presume that this diver ascribes to the theory that a tech diver should be weighted correctly.
(2)---diving in black water, current, touch contact, I realize that there is a lot of **** underwater that can grab you and your gear anywhere. Hence, the recommendation "not" to use a weight harness, even in a regular "tech" dive.
JJ,
Thanks for the kind words. As I said before, it's an interesting job, and somebody's gotta do it, but we'd be hard pressed to call it "fun"!
As for the harness versus weightbelt versus v-weight discussion, our problem really hinges around the ideal versus real-world conditions.
For instance, given the weight of a backplate and the regulator to offset the positive bouyancy of an aluminum 80 near the dive's end, "ideally" we shouldn't need any weight.
Unfortunately, as soon as we start adding things like environmental protection in the form of wet-suits, dry-suits, full-face masks, and so on, we usually need a little extra weight to balance things out.
If all goes well, everything remains balanced, we keep the weight, and don't think too much about it, until we are climbing up the ladder, or trying to get over the hull of the RHIB in heavy chop that is.
If something goes badly wrong, however, such as a punctured and completely flooded dry-suit, or, in my case, a flooded CCR loop, you may find yourself in a situation where it would be good to dump off a little weight. If your choice is whether to pitch the $600 canister light, or a few dollars worth of lead, I bet I know which one most of us would choose!
As for the black-water work, I have never found my harness to be anywhere near the entanglement problem that my search/safety line can be at times. You know how it is. If there is anything out there in the black to hook onto, that damn line has a mind of its own and will try to find it. Of course, add in things like metal detectors and other bits of necessary gear, and its a testimony to the skill and cunning of Public Safety Divers that we don't all end up decorating the bottoms of various lakes, canals, bayous, and reservoirs!
Cheers! Keep up the good work, and stay safe out there!
