Abstract
Abstract A portable apparatus for remotely controlling the launching of disc targets. A multichannel radio transmitter is mounted on a scoring board and a fixed multichannel radio receiver, adapted to receive selected signals from the transmitter, is connected to target launching mechanisms to provide a trigger therefor. The desired launching mechanism is triggered by the choice of the transmitting channel over which a signal is sent.
