I think I have heard this before, why do extra layers of insulation "defeat" the C-4? I have wondered, when reading posts about weighting, whether I use too much weight (apart from any extra that I may need because of wearing unnecessary undergarments). I have a shell dry-suit, 5 lb steel backplate, 5lb negative cannister light and double steel Faber 70s (10 liter - 200bar) - with that I need 8-12 lb extra weight, depending on salt/fresh water, in the form of V-, P- and H-weights (an H-weight was described recently on this list). All that can not possibly come from some extra underware under the Thinsulate. Is it because Faber tanks are lighter than most (all?) other steel tanks or am I still over weighted do you think? When steel tanks are mentioned on here I suppose people are refering to the Pressed Steels which I know are much heavier - here in Sweden they only sell Faber. I have tried how much weight I need in shallow water to keep me down with near empty tanks and wing and I have been graduly adding weight because I have found I need it. I am very slim, so definately not the "floating type", if that makes any difference. Any ideas much appreciated, Dan Ocklind -- Send mail for the `techdiver' mailing list to `techdiver@aquanaut.com'.
