A diver propulsion vehicle (DPV) is an underwater scooter which allows the diver to move more rapidly in the water and cover greater distances. There are a few different kinds of DPV’s and some of them have unique applications.
One of the most popular purposes for underwater scooters is to enhance the deep sea experience of recreational divers. DPV’s add another level of excitement to dive sessions by giving divers’ additional time and scope under water. Without a DPV, a diver has to exert effort in order to swim. This effort translates into deeper breaths and a quicker depletion of the oxygen tank. When using a DPV, the diver just has to hold onto the battery powered underwater scooter which will propel the diver through deep waters.
DPV’s take care of the swimming effort for divers so they can concentrate on the enchanting beauty of the underwater world surrounding them. As divers are not exerting themselves when using a DPV, they can dive for a longer period of time because the air tank they are carrying will last longer. DPV’s are also great for divers exploring a large underwater wreck or a deep cave.

Moving under water is definitely not as simple as moving on land. DPV’s can help marine photographers and directors stay longer underwater to complete their work. An underwater photo shoot or recording requires a lot of movement so if divers can save some energy by using DPV’s they can extend each dive and be more efficient. The best type of machine for underwater filming and photography are tank mounted DPV’s which are hands free, allowing the cameramen to hold onto their cameras while the DPV allows them to ‘fly’ through the water.
Researching deep caves or building anything under water requires a lot of heavy equipment. DPVs are a great transportation method for carrying equipment to the construction site or to take research equipment deep in a cave where it will be used to study the environment or underwater creatures.
The main purpose of DPV’s is to facilitate underwater exploration and work. However, the subskimmer (a specific type of DPV) is one that has an inflatable boat that can be submerged into water. While on the surface the subskimmer is equipped with a gasoline engine as opposed to weaker battery operated propellers used while underwater. The gasoline engine allows the subskimmer to be a useful tow-boat, although the weights that can be pulled have a limited capacity.
The torpedo was a DPV used by various countries during World War II for underwater warfare. Missiles could be attached to the torpedo and two divers with their own scuba gear could ride the torpedo to ‘deliver’ the bomb. Currently, navies around the world use various DPV’s to drop off equipment and combat divers quickly and over large territories. A DPV is much harder to detect by the opposition due to its small size, making its use ideal in certain situations.
