MSD directly oversees an average of 1575 individual customer dives per year; 1100 local Fun Dives and Great Lake shipwreck dives, and on our winter trips - 475 warm water dives. Multiply that out by 63 years, that's 99,225 dives - point is we see a lot of dives and therefore we also see what scuba equipment works and what doesn't. In our history, we have seen a lot of the "latest and greatest" come and go. Before bringing in any new equipment, we take the time to research and evaluate it's performance, reliability, and whether it can handle our rugged cold water (at least at depth, anyway)  local environment.
