I spent the weekend with instructors Ron, Harry, Ryan, divemaster Orr and divemaster candidates Eric, Brad and Will getting 7 students trained as open water divers. We did dives 1 and 2 on Saturday and dives 3 and 4 on Sunday. The vis was crap (3-5 feet) and the water was cold (45°F). The air temp was fine 65-70°F. Because we had an odd number of students, I volunteered to be the partner for Kanda.
