Propelled underwater movement while SCUBA diving has a lot of advantages compared to the normal underwater human powered travel. Underwater SCUBA propulsion devices can provide faster underwater movement and enable the divers to cover greater areas in a limited underwater time period. Most underwater propulsion devices have sensors that detect the vertical velocity of the device. When the descent or ascent is greater than 60 feet per minute, the system reduces the vertical speed by reducing the pitch of the device. These are used in military operations as well as in recreational, sport and other scientific driving activities. |
