Liemke Keiler-25.1

The successful thermal imaging series Keiler by Liemke is being expanded! The Liemke Keiler 25.1 is launching as the fourth model in this series!

This new handheld thermal imaging device, specifically designed for hunting in the forest, presents a variety of sophisticated features and innovative details. Whether for stalking or stand hunting, its 25 mm objective lens and a field of view of approximately 19 m at 100 m distance provide excellent visibility of the target. The popular image quality of the Keiler models continues in this model as well. A 384 × 288 Vox detector and the 1,024 × 768 px OLED display deliver image quality at the highest level. The 2.4x base magnification and 10x digital zoom ensure precise identification. Compact dimensions and intuitive operability are also a priority here. This lightweight device, weighing 445 g, has buttons that are easily accessible from both sides. Even in complete darkness, every button can be correctly selected thanks to the tactile control concept.
