Overview The Armasight Contractor 640 Thermal Weapon Sight is built around our proprietary ArmaCORE™ 12 micron thermal core. It combines extensive detection capabilities and a rich, detailed picture with onboard image processing, wireless communication interface, GPS, and internal memory. The Contractor Thermal Weapon Sight is a premium-component build that is noticeably more compact and lighter weight than conventional thermal scopes. It provides up to four hours of continuous operation on two CR123 batteries—a 50% longer run-time based on lower power consumption as compared to similar units on the market. The Contractor series also offers another first; the turret system that enables users to navigate features, such as digital zoom, color pallet and reticles quickly and intuitively to adapt to changing conditions and environments. The units come equipped with a digital compass and inclinometer that help calculate distance, direction and angles. Like all Armasight products, the Contractor is MIL-STD compliant—allowing for reliable use in all weather conditions. The Contractor series is based on the ArmaCORE™ 12 micron thermal core available in either 640x480 or 320x240 resolution models.
