5.00A must do experience if you never done it. The staff were excellent, friendly and helpful. One on one assistance was very comforting. As a non swimmer, they made it easy and enjoyable. While waiting your turn for the submarine scooter, you can snorkel. A wonderful experience. We would do it again!

5.00Wonderful opportunity to enjoy commuting with the fishes and honu. The fishes are friendly, ok hungry, thay they come up to you. The diving bell accommodates most nearsighted vision. You're not alone, a safety diver and team are with you every every propulsion at a time.

5.00The crew for the scuba scooter were great! This was by far my favorite experience in Hawaii!! The guys were so patient and accommodating. I’m not a great swimmer and I had a broken elbow but they helped me have the most amazing adventure. The photos and video they took were worth every penny too. They helped me navigate the scooter. Helped us see fish and turtles. We weren’t rushed at all. Five stars and more!!
Due to size of the group,...

4.00Due to size of the group, it took longer than expected, but it was still a valuable excursion to book. I would do it again if the opportunity were to arise in the future.
