What can i say other than WOW!!!! FIVE STARS is not enough and i'd give more if i could because what an amazing experience the Submarine Scooter Adventure was. This is a MUST DO activity if you're visiting the island of Oahu and you won't regret it. My wife and i did this a few weeks ago in early June while visiting the island for our 20th anniversary. I saw an ad for this while browsing for things to do on the island and it looked like fun, and man was it ever. From the second you arrive to the second you leave, the guys at Island Water Sports are super professional, courteous and friendly. They make you feel very appreciated and welcomed. After everyone arrives and gets checked in, you take a short boat ride a mile or so out to sea where your adventure begins. The best part is you don't need any equipment or even know how to swim, they provide everything and are with you every step of the way. Once at sea, you take turns getting into the water and then with a quick breath, bob your head underwater and up into the dome of the submarine scooter. Once inside you can breath normally and just have to enjoy the ride. Because you go down 50 or so feet combined with the Submarine Scooter pumping air into the helmet area, your ears will pop and you have to manually blow them out by pinching your nose and blowing out to pop them. Plan to do this a few times in the 10-15 minutes you're under water. They put a compressed hamburger bun inside a metal mesh bag that's attached to the front of the Scooter and have you squeeze it to release small chunks of wet bun, which attracts all kinds of fish right to you. It's an indescribably amazing experience. Each scooter has a diver so you're always being watched and after your time is up they help you rise to the surface and guide you back to the boat. Once back on board, you can just sit and enjoy the views or grab some snorkel gear they provide and go snorkeling on the other side of the boat. You will NOT regret booking this activity!!!
