The Thermtec Hunt 635 Pro is a compact thermal imaging clip-on device with a 35 mm lens and a high-resolution 640 × 512 VOx sensor (12 µm). In combination with ≤ 15 mK NETD (manufacturer's specification), it clearly aims for fine detail representation and clean contours – without becoming unnecessarily large or heavy: magnesium housing at approx. 399 g, IP67, interchangeable battery system, 64 GB memory and monocular mode make it a practical all-in-one package.

Our Assessment – From an Instructor & User Perspective
If you're not just looking for "some warmth" in your clip-on, but rather finer structure and clearer contours, the step up to 640 × 512 is noticeable in practice – especially with changing backgrounds (forest edge, hedges, damp meadows). What's more: the Hunt 635 Pro remains pleasantly compact despite the sensor. The magnesium housing feels robust and high-quality, without making the setup unnecessarily front-heavy.
Practical Added Value: The field of view of approx. 21.9 m at 100 m is invaluable in everyday use, as you have less "tunnel vision" and can more easily place movements within the overall picture – especially when switching between forest and field. At the same time, the ≤ 15 mK NETD (manufacturer's specification) helps you to highlight temperature differences more clearly when conditions are difficult (humid, mild, low contrast).
From our point of view, the monocular mode is a genuine usage feature and not just marketing: you can flexibly use the device as a handheld device without necessarily having to carry a second thermal imaging device. This saves space, weight, and stress during operation.

FAQ
Can the Hunt 635 Pro be legally used as a clip-on device?
This depends on the respective state hunting law and, if applicable, individual permits. Please check the regulations applicable to you in advance.
Can the device also be used as a monocular?
Yes. The integrated monocular mode is intended for this purpose and makes the device more flexible in everyday use.
How long does a battery last?
The manufacturer's specification is approx. 6 hours per battery. In practice, factors such as temperature, display brightness, hotspot/WLAN, and recording functions influence the runtime.
Do I need a special adapter?
According to the manufacturer, the device uses an M52 × 0.75 thread. Adapters must be selected to match this.
How quickly does the device start up?
According to the manufacturer, the start-up time is approx. 3 seconds – practical when things need to happen quickly.
