The Contractor 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 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.

    Great Image Quality

    Posted by Ken D on Sep 21st 2023

    Scope came in a nice softcase with the QDM attached. Very impressed with Kentic QDM. Image quality is great, lots of options to choose from depending on weather conditions and type of environment you hunt in. Very customizable. I really like the PIP mode on zoom. Great quality product, easy to use. Batteries last longer than stated, I would say closer to 6 to 8 hours depending on settings.

    Great Features

    I really like this setup, easy to navigate the menu and zero the scope. Super easy to start recording videos, no sound unfortunately. But lots of image enhancement options. I really like the PIP mode that you can activate on zoom, keeping your optical FOV wide for follow up shots. Would recommend.
