Somehow, every scuba-diving trip is distinct, even visits to well-traveled locations. Pearl Harbor Divers' team, for example, had visited the wreck of the USS Scrimmage, a World War II minesweeper, many times before. But one evening, while slipping through the water above the site, the crew heard a puff of air burst from the ocean, drowning out the motor. A humpback whale then crested just 15 feet from the boat. When the captain cut the engines, the crew realized they were surrounded by whales, which continued to break through the surface and catch breaths tinged with ocean spray in the moonlight.
In the shop, which is certified by the National Association of Underwater Instructors, guides work toward such unique experiences on scuba diving and snorkeling trips. They lead clients—including handicapped divers—to sunken ships, airplanes, lava caverns, and coral reefs throughout the Hawaiian Islands. On these dives, groups encounter common creatures such as sea turtles and native fish, as well as rare marine animals such as shy Pacific bottlenose dolphins, manta rays, and endangered Hawaiian monk seals. The instructors pride themselves on their ability to teach and engage by imparting the facts and historical significance of wrecks. They can also name and discuss each species that divers spot, at least the ones documented by science. On the nighttime Dive the Abyss adventure, divers are tethered within 40 feet of the boat and watch bioluminescent creatures, many of which are still not cataloged by zoologists, arise from depths of up to 2,000 feet.
In addition to dives, instructors conduct courses that work towards open-water or instructor certification. Chatter about past adventures drifts from a full-service pro shop, where technicians sell, service, and repair equipment from brands such as Atomic, Aeris, Oceanic, Mares and Zeagle.
