The ideal optic for the passionate stalking hunter who doesn't want to make any compromises.

The manually focusable 35mm objective lens offers a field of view of 22m at 100m and a detection range of up to 1750 m. Thus, the KEILER-36 PRO (2022) hand-held thermal monocular provides you with a sharply detailed image while hunting at almost any distance. The updated 2022 version of the KEILER-36 PRO impresses with NETD values ≤25 mK, which result in a particularly high-contrast display even with minimal temperature differences. The new, high-resolution OLED display with a resolution of 1024x768 ensures a particularly vivid contrast and intensive color display.


Unmatched image clarity

With its 640 x 512 ceramic VOx thermal detector with a pixel pitch of 12µm, this compact, pocket-sized thermal imaging monocular offers an exceptional viewing experience. The KEILER-36 PRO (2022) model also features 2x optical magnification.


Intuitive operation & long battery runtime

The robust housing and the new user-related menu navigation ensure a simple and intuitive operation – even when wearing gloves. Thanks to the integrated Wi-Fi function, you can transfer image data from the thermal scope directly to your Android® or Apple® device.

The optimized energy consumption of the KEILER-36 PRO (2022) thermal imaging scope provides a battery life of at least 6 hours and can also be operated and charged via an external USB power source. In accordance with strict regulations, the thermal imaging scope is certified according to IP66 standards to provide optimal protection against dust and heavy rain.


High contrast & multiple colour modes

Heat sources can be displayed in various color modes, which can be digitally magnified up to 4x to identify distant game more precisely. Its high-contrast image enables you to clearly see e.g. the belly lines of a wild boar to determine if it is carrying young or not.
