I'm doing a Cavern course in a few weeks and have decided to get rid of the tank weight for that anyway. I think it would be relatively easy to untangle a tank weight (swimming backwards might do it for a simple snag) in most circumstances but why introduce another potential problem. Also, in low vis or night diving entanglement probably would be a bigger concern so to keep the kit the same it would seem logical to remove the tank weight. >I've seen the stuff about a "mediated airway", (at least I think that's what >it is called).

What if you ditch your weight belt? :-) It's not always easy to weight up the benefits and costs or identify where to draw the line between genuine concerns and paranoia. Is airway mitigation a genuine concern or not? I can see how being able to ditch weight to stay on or ascend to the surface is of greater initial importance than a stable position on the surface (in the event you black out and there is no surface support). I guess if entanglement is a major risk factor in some of the environments you dive in then the logical approach (if you keep your kit pretty much the same) would be to make this a higher priority and don't use tank weight at all? Although if you have a good buddy neither should present a real problem (Oh wait, I forgot, we live in the real world) ;-) Cheers, Simon Simon L Hartley EnvSM Website Coordinator\First Year Course Coordinator Associate Lecturer School of Environmental Science and Management Southern Cross University P.O.
