The ThermTec Wild 335 Thermal Monocular is a handheld thermal imaging spotter designed for nighttime detection across mixed country and agricultural terrain. Built with a 384 × 288 uncooled VOx sensor, a 12 µm pixel pitch, and a sub-18 mK NETD rating, the unit pairs with a 35 mm F0.8 objective lens to deliver heat detection at ranges up to 1,800 m. Weighing 485 g without its battery, the monocular features a top-mounted focus wheel and joystick layout configured for single-handed operation, an IP67 waterproof enclosure, and a replaceable 18650 Li-ion battery system providing up to 8 to 10 hours of continuous runtime.

Key Features

• High-Sensitivity Thermal Sensor: Features a 384 × 288 resolution core with 12 µm pixel pitch and NETD ≤ 18 mK to resolve subtle temperature differences through foliage and changing weather conditions.
• Optimised Optical System: Integrates a fast 35 mm / F0.8 manual focus lens providing 3.3× base optical magnification and 1×–4× continuous digital zoom.
• High-Definition Display: Employs a 0.39-inch 1024 × 768 AMOLED screen with 6 colour palettes, picture-in-picture (PIP) mode, and Forest and Target outline modes.
• Ergonomic Control Layout: Top-mounted finger wheel and central joystick allow full single-handed calibration, focus, and menu navigation.
• Connectivity and Onboard Storage: Includes 64 GB of internal memory for video and photo capture, alongside a Wi-Fi hotspot for mobile app streaming via a USB Type-C interface.

Who is the ThermTec Wild 335 Thermal Monocular for?

• Feral pest controllers — identifies invasive species across open paddocks and crop borders using a 3.3× base optical magnification and an 1,800 m detection range to locate heat signatures before planning an approach.
• Deer stalkers — isolates bedding or moving game along tree lines with a 35 mm / F0.8 objective lens and a 384 × 288 uncooled VOx sensor, offering the optical reach required for mixed open country while remaining manageable during extended stalks at 485 g.
• Search and rescue operators — sweeps ridgelines and rural paddocks during nighttime searches relying on the 1,800 m human detection range and a lightweight 485 g chassis suited for continuous handheld scanning.

Less suitable for: Scanning at distances below 50 m where a wider field of view is needed (a shorter 19 mm or 25 mm focal length thermal monocular provides broader coverage), open-plains operations requiring exact target ranging to the meter (a thermal monocular with an integrated laser rangefinder or higher-resolution 640 × 512 core is better suited), or environments outside the rated -20 °C to +50 °C operating temperature envelope.
