Zoom ZH50 is a high-end thermal imaging monocular for outdoor. It has greater magnification and keeps three unique technologies of ZOOM series: Dual Field of View, 1440×1080 HD Resolution and Shutterless Calibration Technology.

With the ZOOM’s patented dual-field-of-view design, observers can seamlessly switch between a wide field-of-view (FOV) for detection and a narrow FOV for target identification. It could be extensively used for night hunting, observation and terrain positioning, search, rescue, and more.

The wider FOV with a focal length of 25mm can be used for target search, while the narrower FOV with a focal length of 50mm can be used for target identification.

The detection distance can reach up to 2.6km. With F-number 0.88/1.1, imaging clarity can be lifted to a new level.

Using a 1440×1080 FHD OLED display, the observation effect is excellent. And the 20×magnification eyepiece makes the target search more accurate, and the observation distance is longer.

The shutterless core module is adopted to nullify the shutter calibration, and simplify the operation.

ZH50 is equipped with an uncooled VOx 12um 640×512 high-resolution sensor featuring NETD ≤25mk (25°C, F#=1.0). With the powerful sensor and image algorithm, better image quality is provided. Even in heavy fog and rain, the built-in ultra clear mode can also result in clear imaging through a more detailed field of view and enhanced object identification capabilities.

Using low-power components and lower power consumption, with a standard additional battery pack and a replaceable 4400mAh large-capacity lithium battery pack, battery life up to 20 hours.

ZH50 is built with a memory of 32GB which can support storing video and pictures. Built-in WiFi module supports APP connection and media transmission.

For different hunting environments and personal habits, ZH50 provides more than 5 colour palettes, including “white hot” “black hot” “red hot” “color” and “hot target highlight”. Switching between different colour palettes is fast and easy.
