Subject: rebreather in cold water

 I was wondering about how a rebreather handles extremely cold water (0 deg.
C to 10 deg.C)?  They work great for the warm caves of Florida and the balmy
water of Hawaii, but what about us Great Lakes divers that have to deal
water ice 4 month a year and a water temp. of Lake Superior Dec. 8 '96 of 3
deg.C. It would be nice to know if they really are practical for this
climate.  Does it make any difference if it a closed circuit or semi-close?
Will they free flow if pushed to the limit?  Are there any rebreather divers
in the Great Lakes area that are using them in the summer and not the
winter? Why?
