Guide Sensmart® TN450


High Quality Thermal…

The TN450 thermal imaging binoculars from Guide feature an ergonomic, classic binocular design, and uses a 400 x 300 17µm <30mK NETD thermal sensor to achieve a detection range of up to 3000m, providing stunning thermal imagery onto a 1024×768 OLED display.


Extremely Sensitive Thermal Sensor

With its 400 x 300 17µm <30mK NETD thermal sensor, combined with its powerful 50mm F1.2 objective lens, the Guide TN450 thermal imaging binoculars present high quality thermal imagery onto a full colour 1024×768 OLED display, with a 1400m detection range when observing a 1.8m tall animal shaped object, or 3000m when observing a 2.3m x 2.3m vehicle.

The generous 7.78° x 5.84° field of view offers excellent observation capabilities, and the 50Hz frame rate ensures thermal imagery is always smooth and detailed, even when observed objects are on the move. For closer inspection of a target, the TN450 binoculars offer a base magnification of 3.2x, with a 1x-4x digital zoom, and eyepieces that can zoom to 13.8x.

Ergonomic Design

Retaining traditional daytime binocular aesthetics, the TN450 remains familiar in the hand, and is always comfortable to use, offering an immersive observation experience. For added comfort, the interpupillary distance is adjustable between 60mm-70mm. The ergonomic design includes raised buttons for easy control of digital functions, reduces fatigue over long periods of observation, and ensures quick and easy use in darkness.

Integrated Laser Rangefinder

The TN450’s built-in laser rangefinder adds further convenience, allowing users to measure distances of up to 600m with an accuracy of ±1m when observing objects in total darkness. These measurements can be taken in both single steps and continuous scanning modes.

Greater Accuracy

The ability to display a magnified image of an object of interest within the field of view increases the TN450’s accuracy even further, highlighting the magnified area within the upper 10% of the viewfinder. This intuitive function allows the user to focus on a specific object without losing control of the observation area.

6 Colour Palettes

6 colour palettes are available, with one-button switching to make palette selection quick and easy. Colour palettes include white hot, black hot, red hot, green hot, iron red, and blue heat.

Multiple Scene Modes

The TN450 offers multiple scene modes – Enhance, Highlight, and Natural – with one-button switching available to assist in adaptive adjustment within different environmental scenarios and situations. To reduce image impurities and highlight the observed target effectively, Enhance and Highlight modes are the best choice.


Drop tested at 1m and with an IP66 waterproof rating, these thermal imaging binoculars are protected against hard knocks, heavy rainfall, and dusty environments. Undeterred by harsh conditions, they will even remain fully operational in extreme temperatures from -30°C to 50°C.

6 Hours of Battery Life

Remaining effective for the duration of observation, the TN450 uses removeable x2 18650 Li-ion batteries, operating reliably for up to 6 hours on a single charge (depending on temperature).

Video Recorder

Users can capture unmissable moments with a built-in still image and video recorder with audio. Videos or photos captured on the device can be stored on the internal 16GB of memory, or they can be stored, downloaded, and shared by connecting the device to the Guide app via Wi-Fi.

Mobile Connectivity

Connect the Guide TN450 to the TargetIR app to use a smartphone or tablet as a second screen, offering a live view straight to the user’s mobile device.

The app also allows full control over digital functions, offers remote recording and still image capture, as well as the ability to view, store, and share photos or videos captured on the device.


Taking Thermal & Night Vision Outside of the UK.

Thermal imaging and night vision products are strictly controlled by ITAR regulations and are subject to UK Government Export Licensing Regulations. Dependent on specification, a licence may need to be obtained prior to the export, even temporarily (e.g. holiday), from the UK.

Additionally, some countries may be embargoed, and no thermal imagers or night vision devices can be taken or exported to them. It is the responsibility of the exporter, whether it be a company or individual, to ensure that such a licence is obtained.

Failure to comply is a criminal offence.
