Pulsar TELOS LRF XT50: 1280 Thermal Monocular Specs

Buy the Pulsar TELOS LRF XT50 when you want a handheld thermal scanner with a 1280-class sensor and a laser rangefinder in one body. Put it to your eye, sweep a field or treeline, range what you see, and keep the rifle pointed in a safe direction until you are ready to aim. SKU 77524 is that tool.

It is not a thermal riflescope. A riflescope carries a reticle and a zero and replaces the day optic; our thermal scope guide is the buying page for that job. It is not a clip-on either. A clip-on sits in front of a day scope so one rifle works day and night; that split lives in the clip-on versus scope guide. The XT50 stays in the hand.

Pulsar builds the XT50 as the top of the upgradeable Telos monocular line: HD thermal image, a wide scan, integrated ranging, and a body meant for long sessions. The 1280x1024 core is the same resolution class Pulsar already used in the Merger LRF XT50 binoculars, moved into a single-eye scanner. If you already own a lighter 640-class Pulsar handheld such as the Axion XG30 Compact, this is the step up in pixels, view, and ranging, not a second aiming optic.

Pulsar rates the TELOS LRF XT50 with a 1280x1024 sensor on a 12 micron pitch, thermal sensitivity below 20 mK, and a 50 Hz refresh. That pixel count is the reason this monocular exists at the top of the Telos line: more native samples across the scene before you zoom.

The 17.5-degree field of view (30.7 m at 100 m) is the other half of that job. A wide view lets you cover a pasture, a cut, or a hillside in fewer sweeps. A high-magnification riflescope does the opposite: it shows a smaller slice in more detail. For handheld scanning you want the wide slice first, then you zoom on a heat source you already found. Compare that view against other handhelds in our thermal monocular buying guide; several 640-class scanners run a narrower horizontal view in exchange for less weight.

Magnification is digital: 2x to 16x, with Zoom Boost extending that to 24x. The zoom ring holds the last setting after shutdown. Digital zoom enlarges the display; it does not add sensor pixels. Picture-in-Picture keeps a magnified inset while the rest of the 17.5-degree view stays on screen. Electronic image stabilization is specified for higher magnification, where handshake shows up fastest.

The 50 mm F1.0 objective and 1920x1080 AMOLED display are the rest of the imaging stack. Pulsar lists three amplification levels (Normal, High, Ultra), nine palettes, and a smoothing filter for low-contrast scenes. Those are processing tools, not a substitute for the 1280x1024 core.

The built-in 905 nm laser rangefinder is rated to 1200 m (about 1,312 yards) in single-shot or scanning mode. That is the reason to pick the LRF XT50 over a Telos without a rangefinder: distance lives on the same device you are already using to scan.

Stream Vision Ballistics can hold personalized profiles and show corrections when you take a range. That does not turn the monocular into a riflescope. The correction is a number on the handheld; the shot still goes through whatever optic is on the rifle. Hunters who range with a separate 905 nm unit can leave that extra device in the pack.

Pulsar moved the rangefinder into a low-profile housing under the body, with a 1/4-inch tripod thread built into that same block. You do not add a separate tripod adapter to put the XT50 on a stick for a long sit.

Buy it if you scan large ground (fields, cuts, mountains) and want 1280-class detail plus a rangefinder without carrying a second 905 nm unit. That is the hunter who already knows a handheld and a riflescope are two different purchases, and who will keep this body for years through Telos upgrades.

Skip it if the gap you actually have is an aiming optic. A dedicated thermal riflescope or a clip-on in front of a day scope is the right spend when the rifle needs to see at night. Skip it if you want a lighter, cheaper scanner for nearby work; the Axion XG30 Compact is that Pulsar, and the monocular guide ranks several 384- and 640-class options below this price.

Night hunting rules vary by state, species, and season. The XT50 is an observation device. Confirm local regulations before you use thermal to take game after dark.

As of October 2026, Thermal Bros listed the Pulsar TELOS LRF XT50 at $4,499.97 under SKU PL77524. That is a US retailer figure, not a Pulsar MSRP. Pulsar's UK store listed the same model at £3,849.95 that month.
