Many of Aquaknots' devoted customers have been patronizing this shop since it opened in the early Seventies, and they're not about to go anywhere else. The proprietors, Manny Seoane and Mario Ginoris, have been around for quite awhile, too. Both were on the sales staff before deciding to buy the store ten years ago. Aquaknots maintains one of the largest inventories of dive supplies in town, and it's the only place specializing in spearfishing equipment. They even produce custom-made spears. Naturally Aquaknots offers classes certified by the Professional Association of Diving Instructors; the beginner course lasts two and a half weeks and includes four open-water dives.
