The Sightmark PVS-14 Night Vision System is the most versatile system on the market. This military inspired unit can be hand-held, weapon mounted or head mounted using the included headgear or helmet mount. The PVS-14 features an integrated 5mW adjustable IR illuminator with low battery indicator and auto brightness control. Automatic shut-off is activated when the unit is exposed to a bright light source, conserving battery life when not in use. The Gen 3 produces a much higher resolution than many night vision units, allowing for a much longer range of sight. This is a must have for the serious night vision enthusiast.
