I'll give protech a nod for equipment and diving too. Miner, Brian, Chris, Bundy, Ana and Peter are all first rate, have great attitudes, and clearly enjoy working together. They took us where we wanted to go whenever we asked. They separated the group by experience and never bitched about someone not keeping up with the group. We dove our dive and they just kept the occasional eye on us. For those who wanted a greater degree of handholding, it was sure available.
We did the Turneffe Elbow trip with ADM, and while the dive masters were super to get to know, very knowledgeable, and had the same general attitudes of the protech divemasters and the dives were first rate, the ADM equipment was unfortunately not. We always take our own gear, but several divers had real issues with the equipment. Two divers were forst to abort due to catastrophic leaks and no back up equipment. I'd not have been happy.
