The water is going to be cold but if he keeps the dives under 25 minutes you guys will be fine. A gallon of warm water dumped into your wetsuit right before you step in the water does wonders for helping you stay warm on the dive. That tent does a good job of keeping you from freezing during the surface interval, that's something a lot of instructors around here are really concerned about. Most of my students this quarter turned down a trip to the Florida springs to do Ohio check-outs in April--did I mention I teach crazy people to dive
I do have one who wants to wait for the water to warm up but the rest are game for 45 degree water in a wetsuit. It will be fun, you guys should join us!
