12 µm Thermal Imaging Sensor
A powerful objective lens in combination with a 12 µm professional-grade thermal imaging sensor provides exceptional detection capabilities. A standard 1.7m (5.58ft) tall object can be detected at a 1300m (1420yds) distance in complete darkness.

Long Detection Range 1298 m
The powerful objective lens combined with a 12μm professional-grade thermal imaging sensor provides exceptional detection capabilities.

High Image Frequency 50 Hz
The 50 Hz refresh rate guarantees that you will capture every moment.

HD Micro-Display
1280×960 high-resolution internal display offers sharp imagery and vivid colours.

Integrated Laser Rangefinder (LRF) 600m
The Finder series has a built-in laser ranging module, which helps to quickly and accurately capture and display the target distance. The ranging accuracy is ±1m and the maximum ranging distance is 600m. Accurate distance readings help to quickly assess the size of the territory, distance and relief. The integrated, precision laser rangefinder provides accurate rangefinding, during both single ranging and continuous ranging modes. Continuous ranging can be quickly activated to adapt to the constantly changing distances of the observed object. 

Pocket Machine
The Finder weighs only 320g, which is lighter than conventional rangefinders, but much more powerful. The compact size of the thermal imager makes it an optimal portable unit for scouting and spotting.

Infrared Sensor Switch
By sensing the reflection, the infrared sensor switch controls the display on and off automatically, which saves power and extends the device's operation time. It also has the advantage of high sensitivity, strong anti-interference ability and stable working performance.

Built-in Video Recorder and  WiFi Connection
With built-in storage space, the Finder series captures and saves moments in the form of photos or videos for sharing with colleagues, friends and family. 

App Supported
Built-in Wi-Fi module provides connectivity of Finder with Android or iOS smartphones or tablets. The smartphone and thermal imager combination offer a set of unique features such as direct image streaming, downloading and sharing recorded files.

Built-in Accelerometer and  Digital Compass
Built-in accelerometer and digital compass improve accuracy by precisely identifying cant and angles.
