What is a submersible Eco-scooter?

Our submersible eco-scooter is a unique and very exciting underwater motor scooter which works with the bell theory. Remember back in school when you would turn a glass upside down in a bucket of water and no water would enter the glass? It’s the same concept, as you descend a seal is formed and you are dry inside the bubble!

Do I need to know how to swim?

You do not need to know how to swim to participate in the Sub-scooter Underwater Adventure. The crew are all certified Dive Masters and Dive Instructors: they will be with you throughout the tour. They will bring the sub to you at the back of the vessel and help you in and out of the unit. You are NEVER alone..

Can anyone do the Underwater Adventure?

Most people can; however, there are a few restrictions: customers must be at least 10 years of age, customers must be at least 4 feet in height, customers must be under 350 lbs., and customers must be in good health. (All customers will sign a medical waiver prior to boarding).

Can I wear glasses or contact lens?

Absolutely! You will have to hold your glasses in your hand when you put your head in the bubble, but then you can put your hands inside the spacious bubble and put your glasses back on. Contacts are fine as well. Just keep your eyes closed and the diver will guide you into the unit. It will be no different than if you were on land.

How deep do you go?

We keep our subs at 7-8 feet at all times. This is less than the deep end of a swimming pool! The sub unit is connected to a floating buoy with a line. Once we descend the sub, you will never go any deeper than the length of the line.

Can the unit tip over?

The unit will never tip over. The bubble produces 110 pounds of buoyancy. Once we add the scuba tank, a 12-volt battery and 60 pounds of lead weight, the unit now has 2 equal opposing forces. The sub is completely neutral.

This product is so new, are you sure it will work?

The units have been around for 13 years and in 10 locations throughout the world. The Navy has even used it for exploration and research. Millions of people have experienced the fun without incident.

Does the engine harm the environment?

The subs are completely environmentally friendly. The unit is not propelled by an engine but uses a 12-volt battery and a switch. Therefore, there are not any emissions going into the water.

How do you prevent the sub from banging into the reefs?

We are very careful with our reefs and the environment and would never permit this to happen. The sub tour is guided and conducted in small groups. Each group is accompanied by dive masters and a predetermined route is followed..

Do I have to have any scuba diving or snorkeling experience to enjoy the sub?

Absolutely not! That is the beauty of the sub scooter, it is suited for almost anyone.

What about motion sickness?

If you have gotten motion sickness previously, I would advise you to take a Dramamine 1.5 hours before your excursion.

What is your cancellation/refund policy?

Cancellations must be received at least 48 hours before tour date and will result in a 3% processing fee. Cancellations made with less than 48 hours notice are fully charged. No shows incur full charges.
