The best thermal monoculars with a laser rangefinder

Why a laser, and not just a better sensor

Everything you normally use to judge distance is missing from a thermal picture. No colour. No haze. No texture on the ground. No fence posts, no grass detail, nothing familiar at a known size. What you get is a white shape on a dark field, and the size of that shape depends on distance and animal size in exactly the same direction — which is why a 3 ft shoat at 180 yards and a 5 ft sow at 300 look near enough identical.

A better sensor does not fix this. Put a 640 on it and you get a crisper shape of unknown size at an unknown distance. A laser fixes it in one button press.

That is the whole argument, and it is why we tell people spending in the $1,000 to $3,000 band to buy the laser before the resolution. The other argument is practical: if you are shooting past about 150 yards, your holdover depends on a number you do not have, and a monocular that ranges means you are not fumbling for a separate rangefinder with a thermal in your other hand.

What the feature costs, plainly

Nothing under $1,000 in our registry ranges. The cheapest rangefinding monocular we could verify sits in the $1,000 to $2,000 tier, which means the laser is roughly the price of a whole second monocular. Whether that is worth it comes down to one question: how often do you need to know the distance before you act?

If you landed here from a search and the top two rows describe your ground, our under-$1,000 ranking will save you a lot of money.

SCAN mode, and why it matters on moving animals

A single-shot rangefinder gives you one number when you press the button. If the animal is walking, that number is stale before you have done anything with it. Pulsar publishes a continuous SCAN mode on the Oryx, which keeps reading and updating while you hold the optic on the target — the difference between ranging a hog and tracking one.

It is a small feature that changes how the optic feels in use, and it is worth checking for before you buy. Note that the practical value drops sharply if you are also handling a rifle: the workflow most people settle on is to range the spot the animals are working, not each animal.

How we picked

We took every thermal monocular in our registry with a laser rangefinder published on the maker's own page, re-read each spec sheet and the warranty terms on September 28, 2026, and ranked on laser reach and stated accuracy, then sensor and lens, then runtime, then what the whole package costs in its tier. Each is scored on our published thermal rubric: sensor and lens for identifying a hog (30%), usability at night (20%), battery and power (15%), durability (15%), warranty and support (10%) and value within its tier (10%). The full rubric is on how we choose.

We have not tested these units. Every figure links to its source, and where a maker omits a number we say so rather than filling it in.

The picks side by side

The picks in context

1. ATN BlazeHunter 335 LRF

The one to buy. A 1,000 yard laser sitting behind a 384x288 vanadium oxide sensor at <18 mK — the most sensitive figure of the four — with 4-32x magnification, an 1,800 yd detection claim, a 0.41 in OLED at 1440x1080 (the sharpest display here), two swappable 18650s rated to 14 hours, Wi-Fi streaming to four viewers, six palettes, IP67 and a five-year warranty at 0.8 lb. It costs meaningfully less than the other three.

The catch is documentation. ATN publishes no lens focal length and no field of view for it, so you cannot compute pixels on target or compare its view with anyone else's, and the 4x base is a narrow starting picture for finding animals in the first place. If those matter to you more than money, the AGM below is the honest alternative.

2. AGM ReachIR LRF 25-384

The best-documented unit in the group and the most compact. A 12 µm 384x288 at <20 mK behind a published 25 mm F1.0 lens, 2.5-20x, a 50 Hz refresh, a 1,200 m detection claim, a 1,000 m laser, a 1024x768 OLED, 64 GB with Wi-Fi, IP67, and two replaceable 18650s, at 0.85 lb. Because AGM publishes both pitch and lens, you can check it: about 17 pixels across a 5 ft hog at 200 yards, 12 at 300.

Two things hold it back. Runtime is rated at up to 4.5 hours per cell, the shortest here by a wide margin — the second battery in the box is not a bonus, it is a requirement. And AGM does not list warranty terms on the product page, which for a unit in this tier is a real omission.

3. Pulsar Oryx LRF XG35

The longest laser and the longest battery. A 640x480 at 12 µm behind a 35 mm F1.0 lens, 2.5-20x, a 1,950+ yd detection claim, and a rangefinder reading to 1,640 yd with the continuous SCAN mode described above. A 1024x768 AMOLED, 64 GB with dual-band Wi-Fi, IP67, up to 12 hours with an external APS 5 pack accepted, and a warranty that reaches five years with registration. At 17.64 oz it is also the heaviest thing here, its standard NETD is published as <40 mK, and it is firmly in the top budget tier.

4. Pulsar Axion 2 LRF XG35

The same 640 sensor, the same 12 µm pitch and the same 35 mm F1.0 lens as the Oryx, in a magnesium body weighing 0.47 kg — roughly a pound less. A 1,750 m detection claim, a 1,000 m laser accurate to ±1 m, a 1024x768 AMOLED, 16 GB with dual-band Wi-Fi, IPX7, and up to seven hours on the APS5 with USB-C power accepted. It is fourth rather than third only because the Oryx beats it on the two numbers this page is about: laser reach and runtime. If you carry the optic all night rather than resting it somewhere, reverse them.

What to look for in a rangefinding thermal monocular

1. Laser reach against your real distances. 1,000 yd (ATN), 1,000 m (AGM and Axion 2) and 1,640 yd (Oryx) are all far beyond any shot you should be taking at night. Buy for the shape of your ground, not the headline.
2. A published accuracy figure. Pulsar and AGM state ±1 m. ATN does not publish a tolerance for the BlazeHunter.
3. A continuous SCAN mode. Single-shot ranging is stale the moment an animal moves. Pulsar publishes SCAN on the Oryx.
4. Battery, because a laser is a power draw. 14 rated hours (ATN) against 4.5 per cell (AGM) is the widest spread of any spec on this page.
5. A published lens focal length. Two of these four have one. Without it you cannot check what the optic actually resolves at the distance you just measured.
6. Swappable cells. All four take a removable battery or an external pack, which is the right answer for an optic you use in long sessions.
7. Warranty. Five years (ATN), five with registration (both Pulsars), not published on AGM's product page.

Using the laser well

• Range the ground, not the animal. Feeder leg, gate post, the corner of the trap. Those numbers do not move and they are what you will actually shoot to.
• Range before you need to. Walk the property once and write down the distances to the places hogs work. Half the value of the feature is available before the animals show up.
• Expect short reads on soft targets. A warm, wet animal in humid air is a poor laser reflector. The headline number is a reflective-target figure.
• Watch the battery drain. Repeated ranging costs runtime, which is why the AGM's 4.5 hours needs planning.
• Pair it with a scope that can use the number. A thermal scope with a ballistic calculator turns a range into a holdover — see our ranging thermal scope page.
• Do not range through brush. The laser will happily read the twig in front of the animal.

Mistakes people make

• Buying the laser when the job is feeder checks. The most expensive unnecessary feature on this site. Paced distances are free.
• Buying resolution instead of the laser. A crisper shape of unknown size is not progress. If you glass open ground, the laser is the upgrade.
• Treating the max range as usable range. Reflective-target figures. Expect much less on an animal.
• Assuming a ranging monocular can aim. None of these has a reticle, a zero or a recoil rating.
• Forgetting the second battery. Especially on the AGM.
