Diver Propulsion Vehicle

A diver propulsion vehicle (DPV), also known as an underwater propulsion vehicle or underwater scooter, or swimmer delivery vehicle (SDV) by armed forces, is an item of diving equipment used by scuba divers to increase range underwater.

DPVs include a range of configurations from small, easily portable scooter units with a small range and low speed, to faired or enclosed units capable of carrying several divers longer distances at higher speeds.
