Thanks to all the staff at Scuba Zen. We had a lovely week diving with them. All of the staff were friendly and helpful, and Tim in particular went out of his way to make our experience the best it could be. We own our own equipment, and had some problems with one BC, and Tim spent quite a bit of time and did his best to straighten it out for us. We dove with three different dive masters, and all were patient and knew the sites as one would expect. For those expecting that your tanks will be changed for you and whatnot, this was not our experience (reason for four instead of five rating). We built our own gear every trip, and changed our own tanks for each dive. Not a huge hassle, but when on vacation it's nice to have that sort of thing taken care of for us. The dive boat was quite comfortable with as many as twelve divers and three dive masters, but be prepared for a back-roll entry, as there is no giant stride platform. After the dives, the staff was very helpful - and always very friendly! We'd dive with them again next time we're in St. Martin for sure!
