My friend and I got into diving about a year ago and logged a few dozen dives already. We did most of these in the chicago area and he has since moved to duluth minnesota. He's been diving in Lake Superior about a dozen times now and nearly half those times he has gotten either full or partial free flows with his regulator (scubapro s550/mk17). We were in lake michigan a few times down to 39 degrees at 130' this summer and didn't have a problem. The only time it happened here was at haigh quarry and it free flowed at 80' at about 50 degrees. He's in mostly low 40s temps now and occasionally dipping into upper 30s. He has had his regulator in for service since this happened. He's heard a few things to help this like not breathing through it until it is under the water and the obvious stuff about not using the purge. I have a mares abyss and I've never free flowed before but I haven't done as many cold dives as him.
Is the s550/mk17 adequate for cold water diving? Is there any kit or any special setting needing to be done to it in servicing for cold water diving? Any recommendations? It would suck for him to have to buy another reg with this one less than a year old.
