Currently, the use of underwater scooters is widespread. Mainly, it focuses on making the most of the bottom time, either by expanding distance covered or increasing the speed you can move about from one point of interest to a next.

Furthermore, they are widely used by technical divers, who need to carry a large, heavy, and voluminous amount of gear. The underwater thruster pulls all that weight, and the diver can advance effortlessly.

On the other hand, divers with disabilities use them to obtain the propulsion that their legs cannot provide.

Is Using Underwater Scooters in Diving Safe?
