Nikon's LaserForce 10x42 Rangefinding Binoculars combine excellent optics with 1,900-yd. ranging capabilities to reduce the number of contraptions hanging from your neck by half. Lead- and arsenic-free extra-low dispersion (ED) glass teams with fully multicoated lenses and prisms to provide exceptional clarity and true-to-life color so you can easily pick out that bedded buck from across the canyon. Long eye relief and twist-up eyecups provide a like-custom fit that won't strain your eyes. Built-in rangefinder delivers excellent accuracy from 10 to 1,900 yds., and includes ID Technology inclide/decline that gives true horizontal distance when ranging in mountainous terrain. Measures in 0.1-yd. increments out to 100 yds. and 1-yd. increments beyond 100 yds. Single and continuous modes let you get a quick reading on a stationary object or follow an object for up to eight seconds to get a continuous reading. Easy-to-read bright red OLED has four intensity settings. Auto-off function conserves battery. Rubber armor over a rugged metal die-cast body ensures backcountry toughness. Waterproof and fogproof. Flip-up lens caps keep debris from blocking your view. Tripod compatible. Uses one CR-2 lithium-ion battery (included). Backed by Nikon's No-Fault repair/replace policy.
