ABSTRACT:
A range finder for use on a golf course comprising a transceiver and a target. The transceiver emits a transmit beam along a transmission axis which is received by the target, and the target returns a return beam to the transceiver. A lens on the transceiver surrounds the transmission axis and focuses the return beam on a detector. Preferably, the lens has a dimension which is about twice the diameter of a retro-reflector mounted on the target.
