Pixfra Draco 635-4K Multispectral Thermal Binoculars Review

The Pixfra Draco 635-4K multispectral thermal binoculars are one of the most compelling multispectral optics currently available — not just because of performance, but because they are typically around £1,000 cheaper than comparable multispectral binoculars from competing brands.

For hunters, deer stalkers, and wildlife observers looking for thermal, night vision, 4K daytime optics, and a laser rangefinder in one unit, the Draco 635-4K delivers serious real-world capability without the premium-brand price tag.

After extensive field use, including capturing clear images of muntjac deer and a hare at night using thermal and night vision, as well as sharp 4K daytime images, it is clear that these binoculars punch well above their price point.

Thermal Imaging Performance – Clear, Sensitive and Highly Adjustable

Thermal performance is where the Pixfra Draco 635-4K really stands out. Detection is fast and effortless, with heat signatures clearly visible even in total darkness or challenging terrain. In real use, locating and observing muntjac at night was straightforward, with excellent contrast and clarity.

The thermal image provides more than simple detection — it allows you to interpret movement, behaviour, and positioning, which is essential for confident identification and safe decision-making.

A major strength of the Draco 635-4K is its customisable thermal colour palettes. These allow the user to tailor the thermal image to their own preference and viewing conditions. By setting palettes that suit your eyesight and environment, you can improve detection, enhance comfort, and reduce eye strain during long observation sessions.

Night Vision with Built-In 850nm IR (Upgradeable to 940nm)

The night vision mode works seamlessly alongside thermal, allowing visual confirmation once a heat source has been detected.

The Pixfra Draco 635-4K features a built-in 850nm IR illuminator, providing strong infrared illumination in low-light and no-light conditions. Importantly, this IR unit is replaceable, allowing users to switch to a 940nm IR illuminator if a more covert, low-glow option is preferred.

In the field, this setup delivered clear night-time images, including detailed observation of a hare, with good definition and controlled digital noise. The ability to move from thermal detection to IR-assisted night vision makes identification far more confident.

4K Digital Daytime Optics

During daylight hours, the Pixfra Draco 635-4K performs as a high-quality binocular thanks to its 4K digital daytime optics. The image is sharp, detailed, and colour accurate, making it perfectly usable as a primary daytime observation tool.

This removes the need to carry a separate pair of binoculars, reinforcing the Draco 635-4K as a true all-in-one, 24-hour optic.

Integrated Laser Rangefinder (LRF)

A key feature that separates the Draco 635-4K from many cheaper alternatives is the integrated laser rangefinder (LRF). Distance information is displayed directly through the optic, allowing quick and accurate range assessment without breaking observation.

For stalking, planning approaches, or assessing terrain, having the LRF built in is a major practical advantage.

Image and Video Recording

Photo and video recording is available across all modes — thermal, night vision, and daytime. Image quality is strong throughout, making it easy to document wildlife activity, review footage later, or share real-world results.
