Photos and video by crew pleasant surprise which we purchased. Thoroughly enjoyed crew hospitality and being among fish and sea turtles. However, wife started to feel congested that evening which turned out to be COVID. As husband is still testing negative days later, our separate helmets with contained air seems like a possible source for wife contracting this virus.

had a great time and the crew was wonderful. my impression was it was supposed to be a 2-hour adventure; fell a little short of that. was an amazing experience
, May 2022
Scooter was amazing and a lot of fun to try don't recommend if you get motion sickness but I'm glad I went on the adventure
, May 2022
Best adventure ever!!! A must do and the entire crew was so amazing. We were very blessed to see dolphins, turtles, and very colorful fishes. The dive was fantastic and easier than expected!
Dissapointing! Doesn't live up to the hype!

This has been my bucket list for a long time and only to be disappointed. First, if your turn is not in the first half hour, you will be seasick 100% guaranteed! I am not easily seasick usually but since they made us wait for almost 2 hrs on the boat, of course you ll get sick. On our boat we have maybe 20-30 people I think and they only had a few scooter so you have to take turn. 1 person is about 20 mins, so just do the math yourselves how long you have to wait! What pissed me off the most is that, it doesn't matter how early you came to check in, they'd still let people who came later than you to go first. I was super pissed about it and they of course didn't care. I had a feeling that the guy who was in charge in assigning who goes next, on purpose put me towards the end because I asked if he can let my husband to go first in the water as he started to not feeling too well. I never had motion sickness this bad ever in my life! I never thew up since I was in first grade but this was unbelievable! My husband threw up 10x and I am not even exaggerating. He hated the experience and this ruined the whole day for us (we were in 9 am tour). And note that 2/3 of the people on that boat either almost threw up or already did multiple times! And when I almost did, I started getting ready to jump in the water to try snorkeling hoping to get better, wearing goggles and fins and all, then the guy called me telling it's my turn now after waiting for almost 2 hrs. When it's our turn, we jumped in and get inside the scooter, I was already nauseous. The first 5-10 mins, the diver guided us around before submerging us down, we didn't see a single fish! The motion was to one direction and it made me even more dizzy. Then after that, they brought us deeper about 8 ft down, then we started seeing fish. Only 2 different kinds though! The blue ones and the silver ones, that's it! When I snorkel somewhere else, I saw more fish than when doing this. Very very disappointing! My husband told me that he was super seasick while in the scooter so he threw up even more during the experience. Oh but the fish loved it though eating his vomit. Lol.. They had a diver took some pictures of us and we look like vampire, so pale and didn't look great at all. So yeah.. So much hope for this tour, only to be disappointed! I read one of the reviews that if you didn't go first, you won't see anything near the surface, which is true and which is why I came earlier with the thought that they would assign it on first come first served basis but NO! You have to be super lucky to come later and get picked first. So good luck! This group who went first, got to see a school of dolphin and then a turtle swimming by them. So guys, maybe if you come late, they'll pick you first. :) P. S. Bring your own gopro so they dont charge you $60 for videos and photos. Don't be a fool!
Not worth the money.

The sub-scooter was a short ride and hurried. Seemed like your personal diver was in control of the scooter, not your throttle or driving. You can see more just taking a snorkeling trip. Pretty calm day and 6 of 35 people got sea sick.
Birthday trip

I went for my birthday. It was amazing, the crew was very friendly. Saw beautiful sea life, Highly recommend .
Fantastic experience
, May 2022
This was awesome! There was quite a few people on our tour that got motion sickness. The boat only goes a mile out you can see the shore. We had such a Great time. So many fish! They’re so beautiful to see. I’d recommend going for sure!!
Some good and some not so much.
, May 2022
The 5-10 minutes when you are at depth are very cool. The other 10 minutes are at best boring. Be forewarned that if you suffer even remotely from seasickness, it will be a big factor on the transport boat and possibly when you come back up from depth and are sitting bobbing waiting to exit the scooter.

Scooter fun!!! Do this!!
, May 2022
This was the highlight of our visit! The staff was helpful & the fish really do come right up to your face! We saw sea turtles, too! The scooter was awesome! Then you could snorkel the rest of the time! Great fun! Only complaint is that we haven't been sent the pictures that were taken under the water even after sending a message! I want to show off the experience but can't without the pics!!

The guides were very capable and patient. My friend cannot even dogpaddle in the water but was able to use this scooter bubble and had the best time of her life. It was amazing. Thank you to the entire crew for a great team job.

Excellent experience! Very different than all the other excursions. The crew was great in helping out everyone and getting pictures. Got to see fishes and turtles up close. Highly recommended for everyone to try.
Oh well
, May 2022
Our adventure was cancelled due to bad weather. There were no openings during our stay so we are on a waitlist.
Must do again! Best crew ever
, May 2022
The team was amazing and patient. They were very patient with the non-swimmers, very reassuring that we would be safe. The divers are with you when your in the scooter which eases my anxiety. There was plenty staff onboard to monitor the scooter divers and also to watch the snorkelers. We saw lots of beautiful fishes, turtles and dolphins. My family enjoyed every moment of this excursion, it’s a must do again when we return to Oahu.
, May 2022
Staff was amazing. Just warning for those who get seasick, take bonine or Dramamine before the trip!!
Great experience
, May 2022
Getting to see the marine life in their natural environment was priceless. I was lucky enough to spend time cruising next to a sea turtle as he swam through the water and would love to do this again.

Great experience!
, May 2022
Great underwater experience. Not for the claustrophobic. Also you go pretty deep atleast 20 some feet down into the water. Very unique experience.
