5.00Bring your own towels to dry. Bring waterproof filming equipment because it will get wet. Your face will get wet. Your hair will get wet. You are required to dive under water for a short amount of time. Only light snacks and water are provided on the boat. No place to change so you gotta already change first before getting onto the boat.
This is a must do if your ever in Hawaii!

5.00Today we embarked on submarine scooters. Lauriant had a thoroughly enjoyable experience. Unfortunately, I am claustrophobic and was unable to participate, as I found it difficult to tolerate the helmet. Nevertheless, witnessing Lauriant's beaming smile upon exiting the water made the experience worthwhile for me.
Just do it!!

5.00This was the coolest experience ever! Couldn’t recommend it enough! My fiancé and I were so excited to do this on our week long vacation in Hawaii and it didn’t disappoint!! You go in the water in the scooter for 20 minutes and you get to see turtles and they have a bag of fish food attached to your scooter and it makes all the fish come real close and swarm around it’s so awesome! We even got to see some dolphins while we were out there.
Amazing experience!

5.00Once in a lifetime experience. Had tons of fun, excellent staff and divers. My wife doesn’t know how to swim and she was able to do this comfortably thanks to the divers. We both enjoyed our 20 minute experience thoroughly and got good pictures out of it.
