When knowing distance is critical to what you do, whether that's outdoor adventures, forestry, construction, utility work or surveying, you need a rangefinder that's fast, accurate, and durable. Meet the LASER 50, a multipurpose rangefinder that quickly measures horizontal distance, actual distance and angle and degrees in 0.1-yard increments up to 2,000 yards* in the toughest conditions.Features:Measurement RangeDistance: 10-2,000 yd.
