What is a Diver Propulsion Vehicle?
A DPV is an item of diving equipment used by scuba and rebreather divers as a form on underwater transportation to increase range underwater during a dive. It usually consists of a battery-powered electric motor, which drives a propeller. The propeller is caged so that it cannot harm the diver, diving equipment or marine life. They are designed so that the vehicle cannot be accidentally started or run away from the diver; and it remains neutrally buoyant under all conditions.
Why Is It Useful?
They are commonly used in cave diving and technical diving where the vehicles help move bulky equipment and make better use of the limited underwater time imposed by the decompression requirements of deep diving, however visibility must be good to make navigation easy.
