Leica 50500 Calonox Sight Thermal Riflescope AttachmentAs all hunters know, positively identifying your target is your greatest responsibility especially when it comes to hunting after dark. The Calonox Sight Thermal Riflescope Attachment is an excellent choice for a nighttime hunting setup and ensures absolute target identification before you take the shot. Unlike night vision devices that need ambient light to operate, the Calonox Sight can operate in complete darkness as it detects heat rather than light. The Calonox Sight displays these heat signatures on an HD display, and the LIO (Leica Image Optimization) function delivers additional image sharpness and clarity. In addition, the Calonox Sight is dual propose device, as it can be mounted on a riflescope or be used as a handheld thermal monocular.
