The crew here consistently earns praise for making divers feel safe and comfortable, whether it's someone's first time or they're getting back in the water after years away. Names like April, Micah, Anna, Olga, and Captain Yoshi pop up repeatedly, with reviewers highlighting their friendliness, patience, and expertise. The operation runs smoothly from start to finish, with well-organized trips and thorough safety briefings that put nervous beginners at ease. Marine life sightings are a major highlight. Expect sea turtles (often in large numbers at cleaning stations), reef sharks, octopuses, eels, and colorful fish across their dive sites. The wreck dives, particularly the Sea Tiger, get special mentions for impressive underwater scenery. One reviewer noted their dive location was underwhelming with mostly sand and few fish, though they praised the crew's professionalism. Overall, the combination of capable instructors, diverse dive options including wrecks and reefs, and abundant sea life makes this a solid choice for both beginners tackling their first dive and experienced divers exploring Honolulu's underwater world.
Great diving with Taylor and April today. Wreck dive with lots of sharks and eels. Reef dive with huge turtles. This dive shop is amazing and we loved our dive masters.
