A diver propulsion vehicle usually pull the diver, only some want him straddling or even sitting. This one we are talking about instead pushes it, applied as it is to the tank on the back. Produced in 1988 in Esperance, America by Underwater Flight Operations, hence the name UFO, it consists of a beautiful faired propeller and a small electric motor powered by quickly replaceable batteries available in different types. The batteries replace all or part of the ballast belt.
A cable connects the motor to the remote control kept within reach of the user, who can set it to Slow, Fast or Off. The device is attached to the tank via a special support, with the resulting advantage of remaining hands-free and without hindrance in front. The thrust of the engine is considerable, assures the manufacturer, so using the UFO involves less effort during immersion, longer stays underwater and longer distances. Certainly true, but who knows if the changes of direction are easy and how much having a device so protruding beyond the tank changes the trim of the diver. Too bad we can't try it.
