PULSAR TELOS LRF XL50 Manual

Telos LRF  thermal imaging monoculars are designed for use both at night-time and during the day and provide exceptional image quality even in adverse weather conditions (fog, smog, rain) and beyond obstacles like branches, tall grass, dense foliage, etc. known to hinder target detection.

Unlike night-vision devices based on electron-optical converters, thermal imaging devices do not need an external light source and are resistant to bright light.

Telos LRF  thermal imagers are designed for various applications including hunting, observation, security, terrain orientation, search and rescue operations, etc.

Telos LRF  thermal imagers are equipped with a built-in laser rangefinder with a range of up to 1000 m and a measurement accuracy of ± 1 m.
