Bill I think your're right. Long deco dives in an ice cold environment sure is dangerous due to loss of mobility, heat loss etc. I think it's a good idea to keep the bottom times short and limit the depth so that you can manage the deco without such devises as heat packs without freezing to death if they fail. As usual this is up to the individual as soon as he/she is aware of the risk. I guess that's the problem in the community - lot's of people are like lemmings - blind followers "if they did it I can too". But who mentioned 300'+ here? I missed that. What we would appreciate are to make the dives we make during the winter a bit more comfortable. These dives are shallower and shorter in bottom time. It's a long and cold boat trip to the wrecks - that's another limiting factor. I guess the heat pack issue was about this - not 300'+ dives Bill. We don't do any technical dives under ice here in Sweden. I don't like the cold very much either. We have to live with it though. Again I think your right about trusting a heat pack during a 300'+ dive or any dive with a lot of deco obligation. /Sigmund Sweden -- Send mail for the `techdiver' mailing list to `techdiver@aquanaut.com'.
