As all hunters know, positively identifying your target is your greatest responsibility especially when it comes to hunting after dark. The Calonox View Thermal Monocular 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 View can operate in complete darkness as it detects heat rather than light. The Calonox View can display these heat signatures on four color pallets: Red Hot, White Hot, Black Hot and Rainbow, each of which gives the hunter a detailed and high-contrast image. In addition, this thermal monocular has a remarkable field of view at 15.5m x 11.7m @ 100m, this wide FOV is especially useful when shooting from blinds and stalking game.
