The Pulsar Telos LRF is the Telos thermal monocular with a built-in laser rangefinder, so you can find, identify and range game with one device.
The Telos LRF XT50 pairs a 1280x1024 thermal sensor with a 50 mm lens, rated to detect a deer-sized animal at up to 2300 m and range targets out to 1200 m. Expect around 8 h of operation and IPX7 weather sealing.

Key Features
- Wide field of view – a generous horizontal field of view (up to 17.5° on the XT50) makes scanning quick.
- HD thermal image – the flagship uses a European-made 1280x1024 HD sensor for fine detail in any weather. Other models use XL/XP/XG/XQ sensors.
- Ring zoom and focus on the lens – focus and smooth-zoom rings sit one behind the other, camera-lens style, for quick one-handed adjustment.
- Precise laser ranging – the built-in LRF has single and continuous scan modes, ±1 m accuracy, and reaches up to 1200 m on the XT50.
- NFC quick pairing (XT50) – tapping a phone to the unit connects Stream Vision 2 with no manual Wi-Fi setup. Currently XT50 only.
- Rubber-armoured housing – grippy in wet weather, hard-wearing, and protects against drops, dust and moisture.
- LPS 7i quick-change battery – more than 8 h per pack. It charges directly over USB-C Power Delivery with no dock needed, and also supports wireless charging.
Best For
- Spotting and ranging for a shooting partner

Frequently Asked Questions
How does the Pulsar Telos LRF XT50 compare with the rest of the Telos LRF range?
The Telos LRF line-up: Telos LRF XQ35 (384×288, 35 mm, 1300 m detection, 1000 m rangefinder); Telos LRF XG50 (640×480, 50 mm, 2300 m detection, 1000 m rangefinder); Telos LRF XP50 (640×480, 50 mm, 1800 m detection, 1000 m rangefinder); Telos LRF XL50 (1024×768, 50 mm, 2300 m detection, 1000 m rangefinder); Telos LRF XT50 (1280x1024, 50 mm, 2300 m detection, 1200 m rangefinder). Larger lenses see further but give a narrower field of view; 640×480 and 1024×768 sensors show more detail than 384×288 at the same distance.
How far can the Telos LRF XT50 see?
Pulsar rates it at 2300 m detection for a deer-sized animal — the distance at which the heat source shows on screen. Recognising what the animal is happens closer than that, and rain, fog and high humidity all shorten thermal range.
How long does the battery last?
Pulsar quotes around 8 h at 22 °C. Battery: LPS7i Li-ion Battery Pack / 6400 mAh / DC 3.7 V.
Does it connect to a phone?
Yes. It connects over Wi-Fi to Pulsar's Stream Vision 2 app to stream live view, download photos and video, and update firmware.
