What is a sea scooter?
Underwater propulsion vehicles (DPV – Diver propulsion vehicle) were invented for military purposes during the World War II. The idea was to extend the distance and/or depth range of autonomous divers by using battery powered propulsion vehicles.
In the early days, mainly the Italian and British Navy used underwater scooters with torpedoes attached to damage battleships. Later, advanced models gain popularity in the diving sector and became used while technical and cave diving. This technology not only helped divers to use the limited time underwater better, but also were useful when carrying bulky equipment.
Nowadays, these smart propulsion vehicles are still in scientific and military application. Moreover, DPVs are widely used by divers both for commercial and recreational purposes. Compact, portable sea scooters are available for swimming and snorkeling too!

How does it work?
An underwater scooter has a watertight body that contains an electric motor and a rechargeable battery. When in operation, the motor drives 1 or 2 propellers depending on the design that are responsible for the propulsion. The swimmer or diver can control the speed. Using a personal DPV helps to reach the desired depths and/or distance within shorter time and with less effort.
Safe construction is important: the propeller cannot harm the user, marine life or other equipment. The DPV must be fully controllable by the diver or swimmer, cannot start accidentally. Removable buoyancy chambers should be included so the vehicle can stay neutrally buoyant underwater.
However, operating such a vehicle is easily learnable, it requires training and awareness. It is important to learn the proper control to avoid dangerous situations such as sudden depth changes or high speed-related injuries, damages.
How much an underwater scooter costs?

The most popular mid-range Yamaha underwater scooters are available for approx. 500-800 USD, while the professional ones like the TUSA SAV-7 EVO line cost approx. 3800-4000 USD.
How fast is a sea scooter?
The main purpose of using a propulsion vehicle is to move faster in the water so the speed is an important feature. Generally they can reach a slightly higher speed when using on the surface than underwater. The speed of course depends on the construction and on the type of the motor.
Cheaper entry level models have a maximum speed of 2-2.5 MPH/3.2-4 kmh. Powerful models like the Yamaha 500li can cruise as fast as 4.35MPH/7kmh.
