Liemke, a leader in high-definition thermal imaging for hunting and nature observation, extends its popular Keiler line with the addition of the German-made Keiler 25.1. This newest thermal monocular has 384x288 pixel resolution, a 12µm VOx sensor, and 25 mm objective lens. The advanced image processing software has two quick-change modes to provide natural looking, detailed images rain or shine. Heat signature detection capability is out to 1,250 meters making this model an excellent choice for hunting in forests or fields. 

The Keiler 25.1 is also easy and intuitive to operate. The central scroll wheel controls the menu, zoom and other functions. The menu has a standard, custom, and basic mode and a quick-access menu that can be customized for frequently used functions. The design makes it easy to locate all important buttons intuitively, even in complete darkness. The Keiler 25.1 also has an internal memory capacity of 32 GB, making it simple to capture photos and videos from your hunt.

“Liemke thermal optics have been a hit with hunters here in the U.S. and those who want to  observe their surroundings and nature at night,” said Jason Evans, CEO, Blaser Group. “The new Keiler 25.1 is the smallest, most compact of our Keiler line. It’s easy to carry in a pocket and delivers powerful performance.”
