Laser rangefinder
The RF1 eye-safe semiconductor laser rangefinder/rifle scope uses coaxial optics with only one objective for sighting and laser ranging functions. To measure range, a hunter would press a button and within a second obtain a three-digit range reading in the scope field of view. Accurate range lessens the chance of only wounding game. Measurable range is 30-600 m to within 2 m.
