Featuring premium optics and powerful distance measurement capability, the Nikon 6x20 Prostaff 1000 Rangefinder will help you take more accurate shots. You'll get 2-yard accuracy when ranging deer as far as 600 yards away; maximum range to a reflective surface is 1000 yards. TRU TARGET technology lets you choose between the closest and most distant objects, which is very helpful when ranging an object while other objects or obstacles are in your view. You can choose between spot readings or continuous measurement for up to 8 seconds, and if a spot measurement fails, you'll automatically have up to 4 seconds of continuous measurement to capture the range. Beyond its ranging capabilities, the Prostaff 1000 is a competent 6x20 monocular, with anti-reflection multi-coated optics for a bright, clear image. Its housing is ergonomically designed for a comfortable grip, the 16.7mm eye relief is helpful to users who wear eyeglasses, and the control buttons are strategically placed for ease of use. Bearing an IPX4-equivalent water-resistance rating, this device isn't afraid of a little rain or snow, and at just 3.6 x 2.9 x 1.5", it fits easily in a pocket or pack.
