Flir Scout II 240

• Handheld 1x thermal viewing: The FLIR Scout II 240 gives a natural, wide-area view that is easy to scan while walking, boating, or checking ground ahead, without the tunnel effect of higher magnification.
• 240x180 microbolometer sensor: Its thermal sensor detects heat rather than visible light, helping reveal people, animals, and objects in darkness, haze, and other low-visibility conditions where conventional optics lose contrast.
• 24° field of view: A broad viewing angle covers more terrain at once, which is useful for surveillance, navigation, and fast target acquisition when movement matters more than fine detail.
• Compact 340 g housing: The light, pocketable body is easier to carry for long periods, so the monocular remains practical as a constant companion in the field rather than gear left behind.
• Waterproof, fogproof construction: The sealed housing and automatic calibration support dependable operation in wet weather, changing temperatures, and demanding outdoor use.

About the Flir Scout II Series

The FLIR Scout II Series is a discontinued handheld thermal-imaging monocular family built for outdoor observation, surveillance, and safe navigation when visible-light optics are limited by darkness or haze. The series includes the Scout II 240, 320, and 640, giving users several sensor-resolution options within the same compact platform. Across the range, the emphasis is on practical field use: a simple handheld format, fast startup, and thermal imaging that highlights heat signatures from people, animals, and other objects regardless of ambient light.

A defining characteristic of the series is its selectable viewing palettes, including white-hot, black-hot, and InstAlert, which let the user adapt image presentation to the scene and the task. That flexibility is useful when scanning mixed terrain, following movement, or separating warm subjects from cluttered backgrounds. The Scout II housing is also built for outdoor conditions, with an IP-67-rated, submersible design that suits rough weather and regular field carry. In the FLIR lineup, the Scout II series sits as a straightforward thermal observation tool for users who need dependable heat detection in a compact monocular rather than a weapon-mounted or recording-focused device.

About the Flir Scout II 240

The FLIR Scout II 240 is the entry-resolution model in the Scout II family, designed for users who need a compact thermal monocular for short- to mid-range detection rather than detailed identification at long distance. Its 1.00x optical magnification keeps the image intuitive and stable in handheld use, which is especially helpful when scanning tree lines, shorelines, trails, or open ground while moving. Combined with a 24.00 ° field of view, it shows a broad section of terrain at once, making it well suited to surveillance, wildlife spotting, and navigation in darkness.

The thermal core uses a 240x180 microbolometer with 60.00 mK NETD and a 9.00 Hz refresh rate. In practice, this setup is aimed at reliable heat detection and scene awareness, helping warm targets stand out from the background without adding complexity to the device. The stated 350.00 m detection range supports early spotting of people, animals, or obstacles at practical outdoor distances. An LCD display with 640x480 resolution presents the image clearly in a compact eyepiece format, while automatic calibration keeps the view usable without manual intervention.

Physically, the Scout II 240 is built as a carry-anywhere thermal monocular. At 340.00 g and 172.00 mm long, it remains easy to keep on hand for extended observation. The waterproof, fogproof housing and 10.00 h battery life make it suitable for long evenings outdoors, and the video output adds a simple way to route the image to an external display when needed.

About Flir

FLIR Systems was established in 1978 to develop infrared thermal imaging systems for airborne applications. The company was headquartered in Wilsonville, Oregon, United States, and became widely known for thermal imaging and other sensing systems used across commercial, industrial, and government markets. In the outdoor optics segment, FLIR built its reputation on devices that detect infrared energy emitted as heat, allowing users to find people, animals, and objects independently of visible light.

Over time, FLIR expanded its thermal expertise through acquisitions including Agema of Sweden in 1998, Inframetrics in 1999, and Indigo Systems in 2003. Its Scout family brought that thermal know-how into handheld monoculars for outdoor use. In 2021, FLIR was acquired by Teledyne Technologies, linking the brand to a broader group focused on imaging, sensing, and instrumentation technologies.
