Seasickness Could Not Spoil Our Fun

My family had a really great time! Even feeling just a bit seasick for two members of my family, they were still able to enjoy their time in the scooter. The crew and divers are professional and made the trip fun. I would love to do it again the next time we are in Oahu!
Awesome experience!

Totally awesome experience! Highly recommend Dramamine!!!! Some kids got sea sick as well. Just something to consider. The crew and staff are very friendly, professional and helpful. You only go down about 10 feet but you will feel some pressure in your ears like in an airplane. Just do what you do on the plane to pop your ears. The water was not cold at all either.

Good adventure

Good crew and very knowledgeable. The only downside is that there isn’t too much variety in the species of fish in the area. Otherwise a fun activity
Lifetime Experience
, Jun 2022
Scary and exciting at the same time! I don’t swim but my diver put my fears to rest and worked with me so I could have an enjoyable experience. It was much louder than I expected but, not bad as long as you clear your ears like they tell you. The fish were amazing and they keep them fed so they come right to you. I can’t wait to get home to upload my pictures and video!
Great time recommend to...
