You said: I would real like to here from the cave divers out there " If cave water was 38*F would you still cave dive?" " Would you use the same gear?" "Go as often?" I do a lot of cave and mine dives in Sweden and it sure is cold water (5c) all the year around so i guess i have no choice. I don't like it but i cant heat the water. I use exactley the same equipment and configuration with a few exceptions that i use when i am in Florida cave diving. The exeptions is that i use five finger dry gloves, argon for suit inflation and i chose a good coldwater reg like the APEX. I have also installed a billyring on my left waist band and i use suicide clips for my stage bottles all this to bee able to connect and disconnect the stages easier. I also use a special inflator hose that is easy to disconnect in case of a inflator freeze up. That is all the small modifications that i have made to my Hogarthian gear configuration and it works great for cold water. Sandy Sullivan wrote: > This is ICE Diving not Cave diving.
