The ThermTec Wild 635L Pro Thermal Monocular is a dedicated handheld thermal imaging unit designed for detection, observation, and target ranging. Built around a 640 × 512 uncooled VOx thermal sensor with a 12 µm pixel pitch and sub-15 mK NETD sensitivity, it captures fine thermal contrast in adverse weather conditions including fog, rain, and high humidity. Paired with a 35 mm objective lens and a 50 Hz frame rate, the device achieves a detection range of up to 1,800 metres and displays imagery on a 0.5-inch 1600 × 1200 AMOLED screen. It integrates a 905 nm Class 1 laser rangefinder (LRF) capable of measuring distances up to 1,000 metres directly from the handheld chassis.

Key Features

• High-Sensitivity Sensor: 640 × 512 VOx sensor with < 15 mK NETD sensitivity resolves subtle temperature differences across complex terrain.
• Integrated Laser Rangefinder: Lens-integrated 905 nm LRF provides distance measurements up to 1,000 m.
• Long-Range Scouting: 35 mm optical system achieves target detection up to 1,800 m.
• Ergonomic One-Handed Controls: Top-mounted manual focus dial and joystick allow ambidextrous operation during continuous carry.
• Robust Field Construction: IP67-rated housing protects against dust and water immersion up to 1 metre across an operating envelope of -20°C to +50°C.
• Removable Power System: Powered by a replaceable 18650 Li-ion battery, supported by on-device USB-C fast charging compatible with standard 5V/9V DC power sources.

Who is the ThermTec Wild 635L Pro Thermal Monocular for?

• Australian professional pest controllers — requires a lightweight 510 g handheld monocular with an integrated 1,000 m laser rangefinder to verify distances accurately during mobile feral pig, fox, and wild dog management operations.
• Feral deer hunters — benefits from the 640 × 512 thermal sensor paired with a 35 mm lens to resolve heat signatures through thick cover at detection distances up to 1,800 m.
• Search and rescue personnel — relies on the 1,800 m detection range and 12 µm sensor resolution to locate missing individuals across low-visibility bushland and adverse weather.

Less suitable for: Spotting targets across open country beyond 2,000 m, where a larger 50 mm or dual-FOV optical system is required, or for direct firearm mounting, which requires a dedicated recoil-rated thermal weapon sight.
