Firefield Spartan 4×50 Night Vision Monocular

$263.99 $219.97


The Firefield NVMT 4×50 night vision monocular is an incredible multi-functional unit. Both compact and lightweight, this versatile monocular weighs only 13oz. Featuring a durable, rubber armored body the 4×50 is weather resistant and completely capable of being taken off the beaten path. The NVMT is held in the palm of your hand so it can be taken anywhere. The built-in Pulse IR system uses a powerful infrared illuminator to provide added light detection under conditions where there is little or no detectable light and the illuminator’s pulsating beam reaches 2 to 3 times farther than other infrared systems and reduces battery drain. The incredible 50mm lens ensures powerful light gathering and light transmission for a pristine image. High magnification with multicoated lenses offers crisp, clear viewing. The monocular also comes with a carrying case and strap.
