The Sightmark® Ghost Hunter 4x50 Night Vision Monocular features a lightweight, durable polymer construction, built for endurance, and a 4x magnification that lends itself well to medium-range observation. The automatic shut-off feature turns the unit off when exposed to bright light sources, saving the night vision tube and ensuring years of operation. Equipped with a high-power infrared illuminator, the Ghost Hunter 4x50 Night Vision Monocular delivers a bright, clear image no matter how dark the conditions and a compact body style for easy travel. Its infrared illuminator catches vivid imaging in low-ambient light conditions or total darkness. Protected by a three-year warranty on the tube and Sightmark's Limited Lifetime Warranty on the housing, the Ghost Hunter 4x50 Night Vision Monocular is engineered to meet the highest requirements and standards of the serious night vision user.
