I was very impressed by the crew - so patient, pleasant, and helpful. Loved scootering to depth to interact with the beautiful fish. Fun!
This is a MUST do when in Oahu

My family was super excited to do this when I booked this adventure. And I have to say, it not only met, it far exceeded any expectations we had. The crew was wonderful and attentive. Highly recommend this little adventure.
One of our best experiences!
Raul_M, May 2023
Me and my fiancé had an amazing time with everyone. This was definitely an experience and a half. The entire team did a great job watching and guiding everyone under water. Would recommend to everyone.
Don’t miss your chance!
Ramon_G, May 2023
A fantastic experience! The crew were so helpful and clearly really cared about making things fun for everyone! When I felt a little claustrophobic, Matteo, one of the crew divers, helped me to find a way to be comfortable, and I ended up having a great time! I also really loved the opportunity to snorkel around the boat on my own. The water was fabulous, and sky was blue, and everything else was beautiful. I would definitely do this again! TY Captain Ogee, Blue, Kakai, and all the others! 😃
Priceless memories!
Cheryl_A, May 2023
Was a wonderful experience! We felt very safe with everyone having their own diver the whole time you were in the underwater scooter. Everyone was super friendly. My daughter got seasick on the boat. Even if you’re not sure you could be susceptible, I recommend to take Dramamine the night before & the morning of.
Excursion unlike any other. Must do!
Melanie_S, May 2023
Awesome adventure even for inexperienced or non-swimmers. The instructors do a fabulous job of getting everyone set up quickly and efficiently for you to enjoy every minute of this underwater excursion. It’s unlike any other we’ve done and highly recommend it!
Must experience!!!
JJ_W, May 2023
Such an amazing experience and great way to see the sea life if you aren’t a great swimmer! The captains and crew were great!
deepak_r, May 2023
Very well organized, very safe. Great technology. Team is very good and great for first times who have not experienced snorkeling
Very cool experience
Kayla_M, May 2023
This was a very unique and fun experience. The water was really rough the day we went so we all got some pretty bad motion sickness but it was still cool to do. We seen lots of fish and a sea turtle. A diver is with you all the time incase you need to go up. Probably not good for anyone with severe claustrophobia or anxiety. Other than that its a must do.
10/10 would recommend
Thabata_F, May 2023
I highly recommend this experience! Some things to note, if you get easily sea sick, I would suggest taking Dramamine or any other motion sickness related things to try and help. Quite a few people on our boat got very sick and ended up not going in the water as a result. The team was fantastic, they walk you through all the steps. They explain the hand signals you need to know while you’re down there, and how to get into the scooter. Each person has a scuba diver that accompanies them while down in the water so it feels very safe the whole time. Seeing the fish literally eating out of your hand right in front of your eyes is amazing. You’re in the scooter for about 20 minutes per person, and after your turn is up you can swim in the ocean and snorkel while you wait for everyone else’s turns. Overall we had a blast and I would highly recommend this to anyone that wants to get the experience of scuba diving without going through the certification (my husband is not certified which is why I opted for this rather than just snorkeling).

Jonathan_S, May 2023
This is an awesome experience! The captain and crew are amazing and put your safety first and foremost. We saw sea turtles and lots of fish even though the sea was turbulent. My wife couldn’t gather up the courage to go in the sub-scooter but still got to see everything from the boat and had a great time.
New experience

Amazing Experience
Nicole_P, May 2023
Amazing experience! My wife and I tried this submarine scooter experience and it was wonderful. I’m not a swimmer so I was somewhat concerned, however the trained divers supported me throughout and I had a blast.
Well worth the time, well worth the money
max_j, May 2023
I was very impressed with the subscooter experience. The staff truly made it an enjoyable and fun experience. They are professionals and make the experience a treasured memory.
Alisha_b, May 2023
Absolutely amazing experience! We had the best time ever. All the staff was super friendly and super helpful. We got to see some amazing sea life. 100% highly recommend.
Awesome ride
Michelle_D, May 2023
The day was kind of gloomy and rainy. The water not so happy to see us. BUT when we got in the subs and under the water that all changed. The fish. The turtles. The sea floor. The captain and the crew are phenomenal. From the music they played to the jokes they told! The underwater sub takes some getting used to to but your diver helps tremendously. Take LOTS of Dramamine if you have any kind of motion sickness for the above and the below.
