The ThermTec Wild 650DL Pro Thermal Monocular (MPN: OPTT-Wild650DLPRO) is a dual-lens thermal imaging spotter designed for rapid detection and target verification across varying distances. Built with a 640 × 512 uncooled VOx thermal sensor (12 µm pixel pitch) and a thermal sensitivity of NETD ≤ 15 mK, it delivers high-contrast thermal imaging to a 0.5-inch 1600 × 1200 AMOLED display. The optical system features a mechanical dual-lens switch between 25 mm (1.8× optical zoom, 17.5° × 14.0° FOV) and 50 mm (3.6× optical zoom, 8.8° × 7.0° FOV) focal lengths, supported by an integrated in-lens Laser Rangefinder (LRF) capable of measuring distances up to 1,000 m.

Key Features

• Dual-Field Optical System: Instantly switch between a 25 mm focal length for wide-area scanning (30.7 m field of view at 100 m) and a 50 mm focal length for long-range identification (15.4 m field of view at 100 m).
• In-Lens Laser Rangefinder: Integrated LRF measures reflective and game targets up to 1,000 m without external bulky modules.
• Extended Detection Range: Reaches human/game target detection ranges of up to 2,600 m using the 50 mm lens setting and up to 1,300 m on the 25 mm setting.
• Continuous Power System: Uses a replaceable 18650 Li-ion battery providing up to 6 hours of continuous runtime per charge, with multi-battery field swapping supported.
• Internal Recording and Connectivity: Features 64 GB internal storage for capturing onboard footage and photos, with a 5V USB Type-C interface and Wi-Fi hotspot support for external viewing.
• Rugged Enclosure: Magnesium alloy chassis with rubberised grip rated to IP67 dust and water resistance, operating in environmental temperatures from -20°C to +50°C.

Who is the ThermTec Wild 650DL Pro Thermal Monocular for?

• Feral pest and wild dog hunters — scans open paddocks and dense scrub using a dual-lens optical system (25 mm / 50 mm) that shifts instantly from a 1.8× magnification wide view to 3.6× optical zoom, combined with an integrated LRF measuring targets up to 1,000 m.
• Search and rescue operators — detects heat signatures across vast search areas at ranges up to 2,600 m using the 640 × 512 uncooled VOx sensor, while documenting operational footage directly onto 64 GB internal storage.

Less suitable for: Shooters requiring a direct-mounting optic for rifle day scopes, who should select a dedicated thermal clip-on system; or hunters operating exclusively in tight forest blocks under 50 m where a fixed single-lens thermal monocular provides a lighter and more practical alternative.
