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 30, a multipurpose rangefinder that quickly measures horizontal distance, actual distance and angle and degrees in .1 yard increments up to 1,600 yards in the toughest conditions. Features: Measurement Range Distance: 8-1,600 yd. (7.3-1,460m) Measurement Range Angle: A 89Adeg Maximum Measurement Distance (Tree): 1,250 yd. (1,140m) Maximum Measurement Distance (Deer): 1,100 yd. (1,000m) Increment Reading Actual Distance: every 0.1m/yd. Increment Reading Horizontal Distance: every 0.1m/yd. Increment Reading Height (upper): every 1m/yd. (100m/yd. and over) Increment Reading Angle: every 0.1Adeg Accuracy (Actual Distance): A 0.50m/yd. (shorter than 700m/yd.) Accuracy (Actual Distance): A 1.00m/yd. (700m/yd. and over, shorter than 1,000m/yd.) Accuracy (Actual Distance): A 1.50m/yd. (1,000m/yd. and over) Magnification: 6x Effective Objective Diameter: 21mm Angular Field of View (Apparent): 7.5Adeg Exit Pupil: 3.5mm Eye Relief: 18.0mm Diopter Adjustment: +/- 4Adeg Power Source: 1 CR2 Lithium Battery (DC 3V) Automatic power shut-off (after approx. 8 sec. unoperated) Size (Length x Width x Height): 3.8 in.
