I have my open water advanced diver certification but it's been years since I last dove (dived?). Dive Maui wouldn't let me partake in their Cathedral boat dive without being evaluated via a refresher course -- and I appreciate their caution. I was happy to take the class, which included a beach dive. I "passed" sufficiently to take a second diver, at Mala Wharf, which was spectacular. I lucked out in having an instructor to myself for both dives, and Joe was fantastic. He made sure I knew what I needed to know and could do everything necessary for my safety, but once assured of my abilities, gave me ample room to enjoy both dives.
