Located next to the Breeze Hotel & BC's bar on the beach. Aqua Dives is one of many tour operations on Ambergris Caye. The boats of the company appear to be well kept. If you choose to go with Aqua Dives they have a few locations that you can sign up for their tours, though there is only one Aqua Dives in Belize. Prices at Aqua Dives are competitive with other shops.
As with every operation there are good and bad employees. Interactions with Aqua Dive dive masters revealed several, but not all, to be disrespectful to their guests and some of the behavior could lead to dire consequences. Examples include flirting with guest to the point of being crude, ignoring some guests both in and out of the water, and drinking with the guests on the return trip. Discussions with other guests revealed many more unhappy with the service they received versus happy about it. Young ladies tended to have the most positive experiences with this company. Additional research revealed several safety issues from Aqua Dive's recent past.
Diving is a very rewarding though potentially dangerous activity. The most important thing is to talk to the dive masters yourself before booking a tour with any company. If you are looking into purchasing a package check their policy on cancellation.
