Pulsar TELOS LRF XL50 Hand Held Thermal Monocular - 50mm <40mK 1024x768px 12um
The Pulsar Telos LRF XL50 is proper top-tier handheld thermal gear—huge 1024×768 HD sensor on a 12µm platform, ultra-sensitive <40mK NETD (with excellent system-level performance), and a smooth 50Hz refresh that keeps the image stable and detailed even when you’re scanning at distance. The 50mm F1.0 lens gives you serious reach, with detection out to around 2300m, and the built-in laser rangefinder takes all the guesswork out of distance instantly. It’s rugged, fully upgradeable, and designed so you can adapt it over time instead of replacing the whole unit.

1. What resolution does it use?
It uses a high-definition 1024×768 thermal sensor with a 12µm pixel pitch for very detailed imaging compared to standard 640 systems.
2. How sensitive is it in poor conditions?
It has a sensor NETD of under 40mK, with system sensitivity effectively around <20mK, helping it separate small heat differences in fog, rain, and cluttered scenes.
3. What is the detection range?
It can detect heat signatures out to approximately 2300 metres depending on target size and conditions.
4. Does it have a laser rangefinder?
Yes, it includes a built-in LRF with a measuring range up to about 1000m and ±1m accuracy.
5. What magnification does it offer?
It provides 2.5–20x magnification with up to 8x digital zoom for fine detail at range.
6. How long does the battery last?
Around 7 hours depending on conditions, using a high-capacity LPS 7i battery system.
7. Is it comfortable to carry?
Yes—despite being a high-end unit, it’s relatively compact for its class at around 700g with battery installed.
8. Is it weatherproof?
Yes, it’s IPX7 rated, so it can handle heavy rain and harsh outdoor use.
9. Can it record video and images?
Yes, it has built-in recording with 64GB internal memory for photos and video capture.
10. What’s the main advantage over lower Telos models?
The jump to a 1024×768 HD sensor and very low effective NETD gives noticeably better detail, especially for identification and separation in complex backgrounds like brush or mixed terrain.
