Pixfra Arc A635 LRF Thermal Monocular | 640 Sensor, Built-in Rangefinder, Lightweight Design

The Pixfra Arc A635 LRF delivers premium thermal performance in a compact, rugged, and affordable unit that rivals more expensive Pulsar and HIKMICRO options. Featuring a 640x512 12µm sensor with <20mK NETD, an integrated precision laser rangefinder, and a high-contrast 1440x1080 OLED display, this is one of the lightest full-feature thermal spotters on the UK market with built-in LRF.

Whether you’re spotting foxes at night, scanning open ground for deer, or just want clear detail in poor weather, the A635 punches far above its price point — delivering fast performance and incredibly clear thermal imagery through Pixfra’s enhanced PIPS 2.0 image processing engine.

Why We Recommend It

We tested the Arc A635 LRF in-house and were seriously impressed. It matches the HIKMICRO Condor 35 in clarity, has a better display than some Pulsar equivalents, and comes in at a lower price with more kit included.

The thermal image is sharp, the button layout is intuitive, and it’s one of the lightest full-spec thermal monoculars available. The integrated laser rangefinder gives instant, reliable measurements up to 1000m and the grip is comfortable for long glassing sessions.

With two 18650 batteries included and easy USB-C charging, it’s an excellent choice for shooters, stalkers and keepers who want 640-level performance without the premium badge price.
