Thermion 3 LRF thermal imaging riflescopes are designed for use both at night-time and during the day. They provide exceptional image quality even in adverse weather conditions such as fog, smog and rain without being hindered by obstacles like branches, tall grass, dense foliage, or other debris. Unlike riflescopes based on electrical-to-optical converters, thermal imaging riflescopes do not require an external light source and are resistant to high levels of illumination. The riflescopes are equipped with a high precision built-in laser rangefinder which allows distance measurement up to 1200 meters. These riflescopes are designed for hunting, target shooting and recreational shooting, observation and orientation.
