The Contractor 3-12x25mm Thermal Weapon Sight is built around our proprietary ArmaCORE 12 Micron Sensor and combines image processing, wireless communication interface, GPS, and internal memory in a single housing that yields a 40% reduction in size and 25% reduction in weight. This translates to pixel size reduction and increased resolution. All combined, the ArmaCORE features represent a 35% reduction in power consumption, allowing the units to run continuously for up to four hours on two CR123 batteries.

The Contractor series also offers an intuitive 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 3-12x25mm is MIL-STD compliant—allowing for reliable use in all weather conditions.

    Built for the Hunter

    Posted by Bill K on Sep 27th 2023

    I really enjoy this scope, the turrets are fantastic when hunting in cold temps, while using gloves. Very easy to use and the menu is very simple to follow. I really like the dedicated record button, makes things easy to capture while on a stand. I wish I could have afforded the 640 version. Batteries last longer then stated in my opinion.
