The Sightmark® PVS-7 1x24 Gen 3 Select Night Vision Goggles are a military-inspired, head-mounted accessory that uses both eyes for superior depth perception in surveillance applications. Extended wear is provided via the head gear, which gives the user hands-free operation. These goggles are based on the most advanced image intensifiers, 57-64 lp/mm, for a better resolution. The goggles feature an automatic shut-off, which turns off the unit when it is exposed to bright light sources. This device includes a green, military soft case with shoulder strap for added protection. Protected by a three-year warranty on the tube and Sightmark's Lifetime Warranty on the housing, the PVS-7 1x24 Gen 3 Select Night Vision Goggles are engineered to meet the highest requirements and standards of the serious night vision user. The device includes a green, military soft case with shoulder strap for added protection.
