Pulsar Thermion 2 LRF XQ50 PRO Thermal Rifle Scope

The Pulsar Thermion 2 LRF XQ50 PRO is the flagship of Pulsar's 384-sensor Thermion 2 PRO riflescope lineup. It takes everything the Thermion 2 XQ50 PRO offers — the same 384 sensor, the same 50mm objective, the same 3–12x magnification — and adds an integrated laser rangefinder accurate out to 800 yards. If you're already running thermal at distance and you're tired of guessing holdover or dragging a separate handheld rangefinder up to your shooting position, this is the scope built for that problem.

What the Onboard LRF Actually Changes

A built-in laser rangefinder doesn't just add convenience — it changes what kinds of shots you can ethically take in the dark. Without ranging, a 350-yard coyote on a windy night is a guess; with the LRF, it's a known distance you can dial or hold for with confidence. The Thermion 2 LRF XQ50 PRO's rangefinder reads out directly inside the scope's display, so you stay on glass instead of breaking position to glance at a separate device.

The 800-yard LRF range comfortably exceeds the practical identification range of the 384 sensor on this scope (typically 400–500 yards before species confirmation gets unreliable), so you'll never out-range the LRF before you out-range the sensor.

The other tradeoff worth knowing: adding the LRF module bumps weight to 2.2 lb (versus 2.0 lb on the non-LRF XQ50 PRO) and pulls about 0.2 lb of that weight forward of the rings. Most hunters don't notice the difference, but if you're already shooting a heavy long-range rifle setup, it's a number worth knowing.

Who This Scope Is For

• Long-range coyote hunters taking shots past 200 yards where exact distance matters for holdover
• Precision predator hunters running dialable scopes or ballistic apps that need a confirmed range
• Open-country and ranch hunters working acreage where targets appear at varied distances and you don't have time to ping a handheld rangefinder before they move
• Hunters upgrading from the non-LRF XQ50 PRO who want the same optical platform with onboard ranging
• Anyone tired of running a separate rangefinder in the dark and wants everything in one piece of glass

If you don't need a rangefinder — most of your shots are inside 150 yards or you're shooting holds rather than dialing — the Thermion 2 XQ50 PRO gives you the same optical performance for less money and a lighter front end.

How It Compares to the Rest of the Thermion 2 Lineup

The LRF XQ50 PRO is the top of Pulsar's 384-sensor Thermion 2 PRO riflescope series. Step down to the Thermion 2 XQ50 PRO if you don't need onboard rangefinding — same sensor, same objective, same magnification range, lighter and less expensive. Step down further to the Thermion 2 XQ35 PRO if your shots stay inside coyote-call distance and you want a wider field of view with a smaller objective. The LRF XQ50 PRO is the right pick when you need the longest reach in the 384-sensor lineup and you want range data in the scope itself.

Frequently Asked Questions

What's the difference between the Thermion 2 XQ50 PRO and the LRF XQ50 PRO? Same 384 sensor, same 50mm objective, same 3–12x magnification, same ≤25 mK NETD. The LRF version adds an integrated laser rangefinder accurate to 800 yards and bumps battery life from 7 hours to 10 hours (the LRF model uses a larger battery pack). Weight goes from 2.0 lb to 2.2 lb. If you want range data in the scope, get the LRF. If you don't, the non-LRF XQ50 PRO saves you money and 0.2 lb.

How far will the laser rangefinder reach? Up to 800 yards on reflective targets in good conditions. Real-world performance on a coyote at night is typically shorter — expect reliable returns on a coyote-sized target inside 500–600 yards, which is well past the practical ID range of the 384 sensor anyway.

Is the Pulsar Thermion 2 LRF XQ50 PRO good for long-range predator hunting? Yes, within the limits of the 384 sensor. The 50mm objective gives you 1,900-yard detection range, the LRF gives you confirmed distance for holdover, and the ≤25 mK NETD keeps the thermal image clean at distance. Practical identification range — where you can confirm species before the shot — is typically inside 400–500 yards on a 384-sensor scope. If you need longer ID range than that, you're looking at a 640-sensor scope.

Does the rangefinder display inside the scope or do you read it externally? Inside the scope. The range reads out directly in the display, so you stay on glass instead of breaking shooting position.

What battery does the LRF XQ50 PRO use? LRF Thermion 2 PRO models typically use Pulsar's APS5 rechargeable battery pack — a larger pack than the APS3 used in the non-LRF models, since the rangefinder adds power draw. Battery life on a single charge is rated up to 10 hours. Most hunters buy a second battery for long sits.

Is the Thermion 2 LRF XQ50 PRO waterproof? It's rated IPX7 — meaning it'll survive heavy rain and brief submersion. It is not designed for sustained underwater use.
