Abstract

A laser transmitter attaches to an arrow emulator secured to a bow and emits a laser pulse in response to bow actuation according to the present invention. The training system further includes a laser-detecting target having a planar array of laser light detectors which detect the location and timing of laser pulses received at the target. Alternatively, the detector may be utilized to detect laser signals impacting a target object, such as a bottle. The laser-detecting target may be connected to a computer which analyzes the target hit information and displays feedback or scoring information. The computer can be connected via a communications network to similar systems so that competitions or training exercises can be conducted across plural geographic locations. The competitions or exercises can be controlled from a central system or unit which may be accessible to individual shooters via an Internet web site.
