Volume means choice. Divers Direct Outlet has both. The 5000-square-foot Florida City showroom is thick with masks, fins, wetsuits, buoyancy compensators, tanks, regulators, spear guns, underwater cameras, and diving computers. This is important because one needs to compare and contrast. Finding the right piece of equipment is absolutely essential with dive gear. No one can afford a leaky mask or an ill-fitting fin 80 feet underwater. Major brands carried include Aqua Lung (formerly U.S. Divers), Mares, Dacor, and SeaQuest. Because Divers Direct Outlet (formerly Divers Outlet) is part of a chain founded in 1984 and based in Deerfield Beach, it can afford to keep its shelves stocked deep. All the workers are certified in the sport, with a scuba instructor and dive master also on staff. The store does teach and certify divers, but they don't try to diversify too much beyond that. Repairs are done offsite in Key Largo. There are no charter trips based out of the shop. "We pretty much stick to retail," manager Candy Tamborrino says, and they do it daily from 9:00 a.m. to 8:00 p.m.
