The Liemke Keiler 25.1 thermal imaging device is pocket-sized and suitable for use in both forests and fields. The device can be operated with either hand and is also comfortable for users who wear glasses.
High-contrast and detailed image quality is achieved through a 25 mm F/1.0 lens and a high-resolution 384×288 px VOx sensor. Thanks to sophisticated image processing software and two quickly switchable image modes, the thermal imaging device delivers a natural-looking image with high detail recognition, even in challenging weather conditions. Additionally, users can select between different color modes. The Extra Dark setting ensures a glare-free image at night.
Intuitive operation is ensured by a centrally positioned scroll wheel, which, thanks to its excellent tactile feedback, is easy to locate even in the dark. This wheel allows you to control the menu, zoom, and other functions. The menu navigation can also be customized, offering a choice of standard, basic, and custom modes, as well as a quick menu. Furthermore, the Keiler 25.1 is ready for use in just five seconds after being switched on and can be operated intuitively with either hand. In addition to the scroll wheel, the controls include a photo/video button, a function button, a menu button, and an on/off/standby switch.

Multimedia capabilities are ensured by a WiFi function, allowing the thermal imaging device to be easily connected to the LIEMKE app. Hunting experiences can be saved as images or videos (32 GB storage) or transferred to a smartphone. The Keiler 25.1 features a live streaming function and USB-C for this purpose.
Eyeglass wearers will also find the Keiler 25.1 thermal imaging device suitable for use with or without glasses. The eyecup is adjustable for comfortable use with or without glasses, ensuring a full field of view. Furthermore, no specific interpupillary distance is required, allowing for unrestricted observation even in challenging situations.
The replaceable battery offers up to 10 hours of runtime and can be fully recharged in just three hours via USB-C fast charging. Featuring a bayonet fitting, the battery is not only quick but also exceptionally quiet to replace. The CHARGER-K (not included), which also functions as a power bank, is available separately as an accessory.
The Keiler 25.1 is a robust and durable thermal imaging device thanks to its aluminum lens, eyepiece unit, and frame. With its fiberglass-reinforced plastic body and rubber inserts, the device withstands even harsh conditions. It also boasts an IP67 rating, making it both dustproof and waterproof for brief immersion.
