1. In a laser range finder, said range finder including a laser transmit section operably emitting laser pulses directed toward a target, a laser receive section receiving laser pulses reflected from said target, a timer timing a flight time for each said pulse from a time of emission of said pulse to a time of reception of said reflected laser pulse, a calculator programmed to operably calculate a range to said target based upon said pulse flight times, the improvement comprising:

  • a) said calculator also programmed to calculate the reflective quality of said target based upon the number of detected reflected laser pulses and/or the ratio of detected reflected laser pulses versus the number of emitted laser pulses; and

    b) a target quality display cooperating with said calculator to display said reflective quality of said target.
