These are purpose made, spring loaded, flywheel or rotational devices especially designed to launch the different types of targets in singles or pairs at distances of up to 100 metres.
These machines vary from the very simple, hand cocked, hand loaded and hand released types to the highly sophisticated, fully automatic variety which can hold up to 600 targets in their own magazine and are electrically or pneumatically operated. Target release is by remote control either by pressing a button or by an acoustic system activated by the shooter's voice.
Target speeds and trajectories can be easily modified and varied to suit the discipline or type of shooting required.
