Zeroing a thermal optic can be extraordinarily difficult, as traditional targets lack the necessary contrast to be able to determine the appropriate adjustments. Enter the Armasight Thermal Target - an easy and hassle free way of zeroing in your thermal weapon sight. The Armasight Thermal Zeroing Target utilizes natural light to provide a target with the temperature differences your thermal imaging device can focus in-on, with a high-contrast center and a surrounding grid of 1x1cm allowing for the fine adjustments necessary to properly zero in your thermal and make sure your dead-on before your next hunt. The Armasight Thermal Zeroing Target has a sticky adhesive backing, allowing for it to be easily applied to a backing and comes as a pack of 10.
