Our family of three adults and two teenagers enjoyed the journey to a reef right off the shore of Oahu for the unique scooters -- we were surrounded by fish. And we also jumped on the Sea-Doo scooters, which was a highlight of our trip to Oahu. The motorized vehicles let us soar through the water and even leap out of it like dolphins. What really impressed us was the large number of people who were dedicated to our safety. There were people on the main boat, on a support boat, above the water, and below the water at all times. Despite being in deep water, we felt well guided by the tremendous staff.

Excellent excursion, I had a great time. Captain and crew are great at what they do and explained everything we needed to know before we "dove" in. Scooters are awesome and easy to maneuver. There were 3 groups and I was in the first one. When I was done I grabbed the snorkeling gear and swam around the boat until it was time to get in. Thank you!

I wish I had more time to drive the scooter myself. Spending $360 for 2 of us and with just 20 mins under the water with less than 5 mins of time to drive the scooter myself self was not what I was expecting. I appreciate the divers as they had to spend most of the time with us under the water. I felt like more I was next to an aquarium. A bit disappointed with the experience.

I went a little under the weather worried about the pressure change in my sinuses but everyone was super helpful and put me at ease. Very nice crew, pics are worth it. Saw mostly fish underwater but then spotted dolphins and turtles overhead. Probably better to go earlier in the day! Got to snorkel around while waiting for others to finish up which was also fun!

Did the submarine scooter activity and what an amazing experience it was. Our boat had 29 people on board and every single person on that boat was amazed by the experience of scooter submarining. The team at Island Watersports makes sure one diver is with each participant underwater at all times. They take amazing pictures which you want to get to purchase to have the memories forever. They are very reasonably priced as well! The amount of fish right in front of your face while underwater is insane! We also saw multiple sea turtles. This was a highlight of our honeymoon in Oahu! What an amazing crew we had lead us!

It is an amazing experience. You'd want to try it at least once in a life. Really need to take some seasick medicine before onboarding.

Great trip and guides. We saw turtles and tropical fish. The turtles kept coming up around the boat. This trip is well worth the money.
