The ThermTec HUNT 635L and HUNT 650L are high-performance thermal clip-on monoculars with an integrated laser rangefinder (LRF) of up to 1,000 meters, designed to combine thermal observation, precision, and a compact, lightweight format. Both models feature a 640x512 pixel, 12 μm thermal sensor, NETD ≤15 mK thermal sensitivity, and a high-resolution 1920x1080 pixel AMOLED display, providing detailed images even in adverse weather conditions and scenarios with low thermal contrast.
The HUNT LRF series is available in two configurations. The HUNT 635L, equipped with a 35 mm F0.9 lens, offers a wider field of view and a detection range of up to 1,800 meters, making it particularly versatile for observation and use at short to medium distances. The HUNT 650L, with a 50 mm F1.0 lens, is aimed at greater distances and extends the detection range up to 2,600 meters.
In addition to the laser rangefinder, the series incorporates advanced features such as a ballistic calculator, E-Zoom up to 4x, AI-driven calibration, Pre-Zeroing system, E-Level, and Zero & RAV One-Shot Sync. Its 2-in-1 design allows them to be used as a clip-on with a compatible daytime optic or as a thermal monocular using the corresponding eyepiece.
Main features
640x512 thermal sensor and NETD ≤15 mK
Both models incorporate a high-sensitivity thermal sensor with 640x512 pixel resolution, 12 μm pixel size, and NETD ≤15 mK. This combination allows for the detection of small temperature differences and maintains a defined image even in rain, fog, humidity, or low thermal contrast scenarios.

Two configurations: HUNT 635L and HUNT 650L
The HUNT 635L uses a 35 mm F0.9 lens and provides a field of view of 12.5° x 10°, equivalent to 21.9 x 17.6 meters at 100 meters, along with a detection range of up to 1,800 meters.
The HUNT 650L features a 50 mm F1.0 lens, a field of view of 8.8° x 7.0°, equivalent to 15.4 x 12.3 meters at 100 meters, and increases the maximum detection distance to 2,600 meters.
Integrated laser rangefinder up to 1,000 meters
The integrated LRF laser rangefinder allows distance measurements of up to 1,000 meters directly from the device, providing precise information without the need for an external rangefinder.

Three-position physical switch
A traditional three-mode switch (on, off, and standby) that facilitates intuitive operation and allows checking the device status at a glance.

E-Zoom up to 4x
The E-Zoom technology allows for up to 4x magnification of the central area of the image. It is especially useful when using the clip-on with low-magnification daytime optics, facilitating the identification and visualization of targets located at a greater distance.
Redesigned ballistic calculation
The new ballistic algorithm ensures that the aiming point matches the impact point, providing exceptional precision and greater confidence in every shot.

Pre-Zeroing System
The pre-zeroing system facilitates initial setup and reduces the time required to align the device, allowing for a faster zeroing process.

Exclusive Observation mode for the HUNT 635L
The HUNT 635L incorporates a specific observation mode that provides more than 50% additional visual coverage. Its larger field of view facilitates exploring wide areas and locating targets.
Full HD AMOLED display
The 0.39-inch AMOLED display offers a resolution of 1920x1080 pixels, providing a crisp and detailed image and favoring comfortable observation during long periods.
Electronic E-Level
The integrated electronic level detects excessive tilt and displays a visual alert to help maintain a correct position and reduce potential deviations of the impact point.
Zero & RAV One-Shot Sync
The AI-assisted system allows setting up zeroing and Recoil Activated Video (RAV) from a single shot, using sound detection and noise filtering to achieve precise activation.
Compact and lightweight design
The housing is made of magnesium alloy to combine strength and low weight. The HUNT 650L weighs approximately 463 g, while the HUNT 635L remains at approximately 460 g.

ThermTec AI Calibration
The artificial intelligence-based calibration technology reduces shutter frequency, minimizing interruptions and image freezing to provide more stable viewing.

Exceptional clarity and detail
It is equipped with a 1920×1080 pixel OLED screen, designed to offer outstanding image quality and reduce eye fatigue during prolonged use.

MORE ADVANTAGES

Lightweight and compact – 463 g
Its ultra-light weight allows for comfortable use without fatigue, ideal for long hunting or surveillance sessions.
Replaceable and rechargeable batteries
Designed to offer continuous autonomy thanks to interchangeable batteries that can be easily recharged in the field.
Revolutionary clip-on with electronic zoom (E-Zoom)
Its E-Zoom system facilitates progressive magnification without loss of image quality, maintaining precision in clip-on mode.
Long detection range – up to 2600 m
The HUNT 635L, with a 35 mm objective, provides a wider field of view and an excellent balance between detail and distance, while the HUNT 650L, equipped with a 50 mm objective, is specifically aimed at long distances and reaches a detection range of up to 2,600 meters.
Recoil Activated Video (RAV)
Starts recording automatically upon detecting the weapon's recoil, capturing the moment of the shot without manual intervention.
High recoil resistance – up to 6000 J
Reinforced construction that withstands powerful calibers without affecting the precision or stability of the device.
Compatibility with daytime scopes up to 16x
Its optical design allows it to be attached to scopes with magnifications of up to 16x while maintaining a crisp and aligned image.
Comprehensive service and support app
Compatible with the official ThermTec application for firmware updates, assistance, and remote control from your mobile.
