The Pixfra Draco D635-4K multispectral thermal binoculars are the top-tier model in the Draco range, built for users who want maximum image clarity, long-range detection and reliable identification across day, dusk and full darkness. Combining a high-resolution 640 thermal sensor, pin-sharp 4K digital day/night viewing, and a built-in laser rangefinder, the D635-4K is a true all-in-one observation solution for stalking, wildlife watching and professional use.
At the heart of the D635-4K is a 640×512 thermal sensor with ≤15mK NETD sensitivity, designed to reveal small heat signatures and fine temperature differences with impressive clarity. This extra resolution gives you better definition at distance, making it easier to spot, track and read animals in challenging terrain or poor weather conditions.
With a detection range up to 1800 metres, the Draco D635-4K is ideal for covering large ground quickly and efficiently. Whether you’re scanning woodland edges, open fields or upland ground, it delivers the reach you need to locate movement early and plan your approach more effectively.
Thermal finds the heat — but identification matters just as much. The D635-4K adds a 4K UHD optical channel for crisp daytime viewing and detailed digital night observation. Supported by AI-powered processing and Pixfra’s WizColour technology, it produces sharp, information-rich images in low light, helping you confirm species and assess surroundings with confidence.
For real-world decision making, the Draco D635-4K includes a built-in laser rangefinder, letting you quickly gauge distance when it counts. It’s a huge benefit for safe approach planning, land management, and ethical shooting decisions in the field.
If you’re comparing models, the D635-4K is the clear step up for users who want the best possible thermal performance in the Draco platform. The jump to 640 resolution thermal brings improved clarity, target separation and confidence at longer distances — while keeping the same easy-to-use multispectral design.
