I do love the diving at Roatan and Anthony's Key dive resort has the capacity to handle a lot of divers which may be part of the problem - too many divers per guide, the worst equipment I have rented, and not much dive guides pointing things out and with everyone diving the same route almost together. As noted by the cruise dive reviewer below. Roatan is still a favorite for diving and I liked my dives there and their resort is beautiful - both recommended by a US Keys dive shop owner that was also along on my dives and using his own gear. I didn't get to catch his opinion of our cruise ship dives this day.
At Roatan I went for the ship's 2 tank dive. At $99 with equipment included this deal seemed as good or better than what I could get on my own. The tour was run by Anthony's Key Dive resort - a very large and popular Roatan dive shop and resort. A good deal except for the equipment - it was the worst I ever experienced. I never recall much trouble with rental gear other than some torn velcro closures or some minor leaks around the low pressure inflator. I thought I checked out my gear enough but when I went to big stride in, I noticed one side of the mouth piece had been bitten clean off and the other side was barely hanging. Underwater I soon changed to the octopus regulator and gave up on the main regulator. Then I was sinking despite multiple minor attempts to puff air into my bcd. The bcd must have had a bad valve stuck open and the air was escaping as fast as I could put it in. Fortunately I must have been near perfect weight. I found out after surfacing that the DM, not being able to fix the inflation problem, took 2, one pound weights out of the back pockets on the bcd. I still noticed the rest of the dive that my bcd wasn't inflating but with proper efforts to control my position I was able to stay barely off the coral the rest of the dive. At least 2 other divers talked to me about problems they encountered with their Anthony's Key rental gear - regylators and bcds. I dived Roatan once before from a cruise ship in a different area and thought it was fantastic, Anthony's Keys was no different - keeping Roatan as one of my top fav dive destinations - nice wall on the first dive, lots of marine life, and lots of hard coral and small canyon with sandy bottoms through the coral. Similar on the second dive plus we got to briefly visit an old steel ship wreck in about 70-80 feet of water. Changed gear on the second dive served me well except for some minor leaks around the low pressure inflator and the gauges connection. I felt the dives were great, a good value, but their equipment was too used and a little scary. The dive operations/guides etc didn't seem into it that much.
