Upgrade your nighttime shooting setup with the Collector 640 Thermal Weapon Sight. It utilizes a durable, yet lightweight ULTEM Composite Body, giving it a weight of just under 1 pound to ensure a minimal effect on weapon handling characteristics. The heart of the Collector 640 is the exclusive ArmaCORE 640x240 12um Thermal Core – a powerful sensor that can detect a human sized heat signature at 932 meters, recognize the target at 233 meters, and identify the target at 146 meters. Heat sources are projected onto a high definition XGA 1024x768 OLED display, and are viewable in multiple color palettes. This allows the Collector 640 to be adapted to meet individual preferences or to specific environmental conditions. Other features include the Iron Wolf thermal technology platform. An extensive suite of features includes video and image capture, USB video stream, USB-C interface for viewing your recordings and photos on external devices such as computers or televisions.
