5.00One of the most amazing experiences of my life. The crew was extremely helpful and kind. I got seasick and they were so helpful. The pictures they take underwater are worth every penny! Budget another $20 per person to get the pictures. You’ll thank me later!! Also please tip your crew! They work very hard to give you an amazing experience!!
A must do!

5.00This was an incredible experience! I recommend taking some Dramamine—even if you don’t usually get seasick—because the conditions on the water can be very different from those on land. Also keep in mind that it’s fairly loud inside the sub, so bringing some ear protection (Wax) is a good idea. The crew was fantastic—friendly, knowledgeable, and happy to share insights not only about the ocean but also about the local area. If marine life interests you, this is something you definitely shouldn’t miss. We saw rays, turtles, and tons of fish! The photos taken by the guide turned out great, and we captured some amazing footage on our GoPro and underwater cameras.
Try it out and swim with the fishes

4.00The scooter is actually pretty darn cool and the captain and the crew who came and went diving with us were friendly and knowledgeable. We saw turtles and had fish food so the fish came very close to us. My issue was just with me— I had trouble with the pressure in my ears and no matter what I did it just wouldn’t pop. It could also be because I was going up and down depths with the diver so neutralizing was difficult but I just made good of the experience. I also get seasick very quickly and the captain helped me with an essential oil to help ease it and it helped. All in all it was a cool experience that people should try at least once.
Fantastic

5.00Better than snorkeling if you find the mask and snorkel uncomfortable. Your head and shoulders are out of the water. You breathe easily and get to see all kinds of fish and turtles and we also saw a stingray and a small octopus! Divers everywhere and I felt so safe. We snorkeled around the boat after our turn was done. Fine crew. Absolutely worth every cent. Thanks!
Went bonkers underwater

4.00Crew and divers were professional. My diver was patient and respectful with me, even when he had to force my head into the diving bubble (I was a thrashing mess, due to my fear of water,and uncoordination) The diving experience was nice, despite the bonk to my forehead I received whilst entering the vehicle. Overall...a good experience that I really would recommend trying.
Awesome time

5.00If we come back to Hawaii I would definitely book this excursion again! Coming from Texas it was absolutely 💯! The crew made it a wonderful experience! And saw tons of fish and turtles! It's worth the money! If we had time I'd go on it again while we ate here! Thank you!

5.00This is an amazing experience and worth doing at least once! The staff is extremely helpful, nice and considerate. They make you feel safe and comfortable throughout the process. I recommend getting the pictures and videos once done. A plus not knowing how to swim but can still do the excursion.
