A handy thermal imaging monocular from the renowned Burris company to facilitate night observation. The BTH 25 model is equipped with a variable optical magnification of 1.7-6.8x. For greater observation accuracy, the model also offers a digital zoom of 1-4x, which allows you to spot objects up to 1200 meters away (vehicle detection) .
