The Trijicon Download Cable allows you to download the images captured by the Image Capture feature on IP-Patrol series thermal monoculars and the IR-Hunter Mk. II thermal scopes. The cable also allows the scope to be attached to a video recorder allowing you to record what the optic catches during operation. If you plan on keeping the images you take on your device or what to take videos of a night hunt or surveillance operation this accessory is a must have.
