Type: Thermal monoculars Brand: Liemke
The Keiler 25.1 is the current entry model from German brand Liemke. It uses a 384×288, 12 µm VOx detector quoted at 40 mK behind a 25 mm F1.0 lens, giving a 2.4x base magnification, a 10.5° field of view (18.5 m wide at 100 m), digital zoom up to 10x and a stated detection range of 1,250 m.
It has a 1024×768 OLED display, records photo and video to 32 GB of internal memory, and streams over Wi-Fi to Liemke's app. Power is Liemke's removable BP-K lithium pack, rated at up to 10 hours. The body is IP67, 147 mm long and 445 g. Liemke sells it simply as the Keiler 25.1; there is no "Pro" suffix on the maker's site.
It suits mixed farmland and woodland edges, and buyers who want a European-supported unit with a long swappable battery at a 384 price. Its 40 mK sensitivity trails the most sensitive current 384 sensors on damp nights.
