This unit consists of a solenoid so arranged that when the circuit is closed, one ball is dropped and the other is then thrown horizontally. Both balls strike the floor at the same time. This unit is very helpful when used with a stroboscope for photographing falling bodies. The remote control features make it a superior device for demonstrating since the instructor does not have to be right on top of the equipment to operate it. Unit comes with a 3m cord and line switch, two balls, and instructions. Mounting rod is included for clamping (tripod, vertical post, and clamp are not included).
