The InfiRay FH35R is equipped with 12μm 640 × 512 pixels high resolution sensors with NETD ≤35mk and uses an OLED display with a resolution of 1024×768. In combination with an optimized image algorithm, it creates a stunningly clear image.
For a better visual experience, Finder II supports switching between cold and warm image tones. By setting the cold tone, users can get visually clearer imaging quality with rich detail and highlighted targets. A warm tone setting provides softer imaging to avoid eye fatigue from prolonged use.
The Finder II series has a built-in laser rangefinder module that provides both single and continuous range, helping you to pinpoint the target’s distance accurately. Accurate distance and terrain assessment is quick and easy with an accuracy of ± 1m over a range of 800m.
Long detection range 1818 m
The 35mm lens combined with advanced thermal imaging equipment provides exceptional detection. The FL35R and FH35R boast a detection range of up to 1,818 meters in complete darkness.
The built-in thermal technology in the Ultra-Clear InfiRay mode consists of software algorithms designed to work in difficult weather conditions such as rainy, snowy, foggy days, etc., which increase the clarity of the thermal image and bring out the details in the image. Ultra-Clear mode can result in a more detailed field of view and improved object identification capabilities.
The battery can be quickly removed and replaced with a new one within seconds. Thanks to the removable lithium-ion battery, you can enjoy up to 6 hours of battery life. Carrying an extra battery as standard can extend the battery life up to 12 hours.
The Finder II series is equipped with 32 GB of digital video and photo memory. Saved videos and photos can be transferred to a computer via a wired connection or to a phone via Wi-Fi.
The Finder II series and the InfiRay Outdoor App work hand in hand, easily handling frame sync and data output. The app offers additional features such as access to the InfiRay online community and after-sales support.
