The Pulsar Telos LRF XT50 is an ultra-high-definition handheld thermal imaging monocular engineered for long-range detection, open-country wildlife surveying, and professional pest eradication. Built around an uncooled 1280 × 1024 European-made microbolometer with a 12 µm pixel pitch and a system NETD rating of under 20 mK, the monocular resolves fine anatomical details at extreme distances. It pairs a fast 50 mm F1.0 germanium objective lens with a 1920 × 1080 Full HD AMOLED display, delivering an optical base magnification of 2.0×, smooth digital zoom up to 16× (expandable to 24× with Zoom Boost), and a wide 17.5° horizontal field of view. Weighing 0.73 kg with its removable LPS 7i Li-Ion battery pack, the Telos LRF XT50 features an integrated 1200 m laser rangefinder, Electronic Image Stabilisation (EIS), and an IPX7-rated waterproof housing for demanding field operations.

Key Features

• Ultra-HD Thermal Sensor: Features a 1280 × 1024 resolution sensor at a 12 µm pixel pitch with sub-20 mK sNETD sensitivity for exceptional contrast and clarity in adverse thermal conditions.
• Integrated Laser Rangefinder: Class 1 905 nm rangefinder measures target distance accurately to ±1 m across distances up to 1,200 m.
• Extended Detection Envelope: Detects standard deer-sized heat signatures at ranges up to 2,300 m with a minimum focus distance of 5.0 m.
• Electronic Image Stabilisation (EIS): Reduces blur and user hand-shake during high-magnification observation.
• Rugged Power Architecture: Powered by a replaceable 6400 mAh LPS 7i battery delivering 7 to 8 hours of runtime at 22 °C, with USB Type-C Power Delivery and wireless charging support.
• Onboard Storage and Connectivity: Includes 128 GB of internal memory, dual-band Wi-Fi (2.4/5 GHz), and compatibility with the Stream Vision 2 and Stream Vision Ballistics apps.

Who is the Pulsar Telos LRF XT50 Thermal Monocular for?

• Professional pest controllers targeting wild dogs and pigs — benefits from the 1280 × 1024 resolution sensor and < 20 mK sensitivity to identify invasive predators against cluttered thermal backgrounds before ranging them out to 1,200 m.
• Hunters conducting open-country deer management — uses the 2,300 m thermal detection range and 17.5° field of view to scan broad landscapes while retaining a handheld 0.73 kg total carry weight.
• Search and rescue operators — relies on the 2,300 m detection threshold and integrated 1,200 m laser rangefinder to locate and position heat signatures across large operational perimeters.

Less suitable for: Hunters operating exclusively at close ranges under 150–200 m in thick bush (where a lower-cost 384×288 or 640×512 compact thermal monocular is more practical) or shooters requiring a direct weapon-mounted optic for live firing (who require a dedicated recoil-rated thermal riflescope).
