The ThermTec Wild 350D Dual FOV Thermal Imaging Monocular (SKU: OPTT-Wild350D) is a handheld thermal observation device engineered for nighttime pest control, game stalking, and search operations. Featuring an uncooled 384 × 288 VOx microbolometer with a 12 µm pixel pitch and sub-18 mK NETD sensitivity, the unit delivers clear thermal detail on a 1024 × 768 AMOLED display. Its mechanical dual focal length optical system allows operators to switch between a wide 25 mm field of view for rapid scanning and a magnified 50 mm focal length for long-range target identification.

Key Features

• Dual Optical Field of View: Switch mechanically between a 25 mm f/0.9 lens (2.4× base optical magnification, 10.5° × 7.9° FOV) for scanning and a 50 mm f/0.9 lens (4.8× base optical magnification, 5.3° × 4.0° FOV) for detailed identification, reaching up to 19.2× with continuous 1×–4× digital zoom.
• Detection Range: Provides human/vehicle target detection ranges up to 1,300 m on the 25 mm setting and up to 2,600 m on the 50 mm setting.
• Sub-18mK Thermal Sensitivity: High-sensitivity sensor paired with AI-driven self-learning calibration maintains continuous image clarity for up to 1 hour without manual recalibration freezes.
• Extended Power Supply: Powered by replaceable and rechargeable 18650 Li-ion batteries, offering 8 to 10 hours of runtime per battery and up to 20 hours combined runtime across the two included packs.
• Media & Connectivity: Equipped with 64 GB of internal storage, USB Type-C data/charging interface, Wi-Fi hotspot connectivity for mobile devices, and a standard 1/4"-20 tripod mounting thread.
• Rugged Housing: Rated to IP67 dust and waterproof standards with an operational temperature range spanning -20°C to +50°C.

Who is the ThermTec Wild 350D Thermal Monocular for?

• Nighttime Pest Control Hunters — Requires the dual focal length system of this dual-field-of-view thermal monocular to switch from sweeping paddocks at a 1,300 m detection range on the 25 mm setting to confirming feral pigs, wild dogs, or foxes at up to 2,600 m on the 50 mm setting without optical resolution loss.
• Game Stalkers — Relies on the 12 µm, 384 × 288 thermal sensor to detect subtle heat signatures through heavy bush canopy at 2.4× base optical zoom and track targets into open country at 4.8× base optical zoom using a single 697 g handheld device.

Less suitable for: Direct firearm mounting, which requires a dedicated thermal rifle scope or clip-on optic; precise target ranging under 1 m tolerances, which requires an integrated laser rangefinder module; or extreme long-range open-country identification requiring a higher-resolution 640 × 512 thermal sensor.
