Ed Hewett measures his experience not just in years, but also in dives—he’s plunged into American freshwater lakes and the world’s oceans more than 5,000 times. As the course director at Dive Pros, Hewett leads a team of NAUI- and PADI-certified scuba instructors and dive experts as they train students individually or in groups of up to 20 during basic and advanced open-water certification courses. Seasoned divers seeking deeper instruction can pursue Nitrox, Rescue Diver, and Instructor Trainer courses or ask for tips on how to balance beach balls on their noses underwater. Though instructors train locally, they also lead group dive trips to the cerulean waters of Cozumel, the Galápagos Islands, and Roatán—the largest of Honduras's Bay Islands. To equip divers for each plunge, the team also deals in trusted equipment by brands such as ScubaPro, Oceanic, and Bare.
