The Tracker Pro™ 3x42 night vision binocular allows for incredibly detailed observation ability under the darkness of night.  This revolutionary night vision binocular is completely self-contained and is able to work up to 10 hours on one 3V battery.  The Tracker provides clear viewing in total darkness by utilizing a built-in IR infrared illuminator; when in use the illuminator emits a pulsing frequency that is so energy efficient it creates less battery drainage and prolongs battery life.  The ergonomically designed rubberized body is surprisingly lightweight, features a no-slip coating and can be taken on long expeditions both easily and comfortably.  The Tracker utilizes the revolutionary Eclipse™ Lens Cover System, which uses flip-up covers that can be easily clipped back against the body of the binoculars and rotated out of the user’s viewing area while eliminating lens cap hassles.  Pin holes in the lens caps allow the Tracker to be used in the daytime when the caps are closed.  Also featured is a dual diopter adjustment with central focusing knob, a fixed eye span and fully multicoated optics.  The Tracker 3x42 is backed by Yukon’s Limited Lifetime Warranty.
