The DS series scopes feature an 800A-800 LCD circular digital display that delivers high-resolution images and rich contrast. The extra wide field of view provides exceptional environmental awareness. User experience will closely resemble a traditional glass optical scope.Sighting your scope has never been easier. After taking your first shot simply move the digital reticle crosshairs to the actual impact point of the projectile on the paper target and save this location in the device. The device will automatically recenter the reticle crosshairs and adjust your new center point to where it should be located for future shots. 1 shot that's all it takes!Designed with 100mm of eye relief the Nightstalker 4K ensures a safer shooting experience and reduces peripheral light.
