Liemke Keiler 25.1 Thermal Imaging Monocular
Liemke Keiler 25.1 Thermal Imaging Monocular is available to backorder, order now and we will ship as soon as possible (typically within 3 to 10 working days unless notified otherwise).
The Liemke (by Blaser) Keiler 25.1 offers a brilliant image with <40mK NETD 384x288 pixel 12μm VOx sensor and 25mm lens. The mature image processing software and two quick-change image modes for different observation conditions provide a natural looking image with very good detail identification. With the five color modes, you can use the device according to your preferences.
All hand-held thermal imaging devices from the Keiler family impress with their premium quality. They have the same functions and features, but differ in the detection range, field of view, sensor, and lens. Whether you want an all-rounder or a specialist depends greatly on the conditions in your hunting grounds.
The central scroll wheel is the main control element: It can be used to intuitively control the menu, zoom, and other functions. The menu structure with standard, custom, and basic mode and the quick-access menu can be customized, allowing you to quickly access frequently used functions. The excellent tactile design allows you to locate all important buttons intuitively, even in complete darkness. Get ready: After switching on, the device is ready to use in just five seconds!
The battery lasts for up to ten hours and can be recharged with the fast charging function in just three hours through the USB-C port. The battery can be changed quickly and silently thanks to the bayonet mount.
Thanks to its WiFi function, it is easy to connect the Keiler-25.1 – just like the Keiler-1 and Keiler-2 – to the Liemke app. Photos and videos can also be stored conveniently to preserve your hunting memories for later on!
