ABSTRACT:
A laser rangefinder bow sight adapted for use preferably with a conventional multi-pin bow sight having a frame and a plurality of sighting pins adjustably positioned on said frame. The laser rangefinder has a housing removably fastened to the bow sight frame. The housing supports a laser transmit section, a laser receive section, a precision timing section and a central processing unit (CPU) for measuring distance to a target coupled to an LCD display. The CPU also provides outputs to a plurality of range window indicator lights which are preferably LEDs. The indicator lights may be externally mounted to the bow sight pins or mounted within the rangefinder housing. In the latter case, a plurality of optical fibers are connected to the distance window lights in the housing. Each of the sighting pins is optically coupled to a separate one of the plurality of distance window lights via one of the optical fibers. The rangefinder is actuated via a remote trigger switch connected through the power supply in the housing to each of the sections. When the rangefinder is triggered, the CPU determines the target distance and activates one or more of the distance window LEDs for the range window or windows closest to the measured distance. Light is then transmitted via the optical fibers to the sighting pins, thus illuminating the one or two sighting pins corresponding to the measured distance. The display is held for a predetermined period of time or until the archer actuates the remote switch to take another distance measurement.
