Arlington Scuba Center, Arlington

A PADI five-star diving facility, Arlington Scuba Center, Inc. first opened its doors in 1972. Since then, the shop's scuba instructors have helped countless divers obtain PADI open-water certification. The lessons start within the facility's classroom and pool and eventually progress to natural locations, such as the five-story bathtub at Scuba Ranch, so students can complete dives in real-world conditions. Aside from this standard certification, the staff teaches advanced courses in which students can train for search-and-rescue missions or float above the hull of a sunken ship. Back on dry land, staffers man Arlington Scuba Center's dive shop, where they sell fins, masks, and other equipment from respected brands such as Aqua Lung and Henderson.
