An automatic target device having targets hingedly mounted to a endless loop conveyor which is driven by a variable speed, remotely controllable drive motor around an endless track having a target track where the targets are presented for target practice and a return track where the return track is
An automatic target device having targets hingedly mounted to a endless loop conveyor which is driven by a variable speed, remotely controllable drive motor around an endless track having a target track where the targets are presented for target practice and a return track where the return track is lower than the target track, and having a target rail that targets slide upon and that holds the targets in an upright position along the target track. The target device makes an efficient use of gravity to maintain upright targets in an upright position and to reset toppled targets into the upright position. The target device includes a forwardly canted deflector plate to protect the device. The deflector plate, endless loop conveyor and target rail may all be canted forward in substantially parallel planes thereby allowing for a compact mechanism and facilitating portability. A method for providing moving targets is also disclosed.
