Submarine Scooters

2.00They are making a fortune of these scooters $200 for 20 min in water max depth 10 feet. Not worth the price and when got to shop they had some completely other deal. I was 10 min late it’s far away 1hr from most places keep that in mind had to pay $20 for water taxi which was reasonable. If you know how to snorkel just do a snorkel tour which range from $60-120 and you get up to 3hrs on water. I would maybe do this activity if it was $80 but $189 is a rip off. Everything in Hawaii is expensive

2.00At almost $200 it didn’t measure up what I expected for that kind of money. You only get 20 min in the water max depth of 10 feet. You go in groups the rest of time you can snorkel or stay on boat not worth it
