The ThermTec Cyclone 625 Thermal Monocular is an ultralight, pocket-sized thermal spotter engineered for short-to-medium-range detection and rapid area scanning. Featuring an uncooled VOx 640 × 512 thermal sensor with a 12 µm pixel pitch and a thermal sensitivity of NETD < 20 mK, the unit resolves minute temperature differences in challenging conditions. The sensor pairs with a 25 mm F1.0 objective lens and a 1024 × 768 AMOLED display to project a wide 30.8 m field of view at 100 m, with a human and game detection range reaching up to 1,300 metres and positive identification rated to over 430 metres.

Key Features

• Shutterless Calibration: ThermTec AI shutterless technology eliminates mechanical calibration clicks and image freezing during active observation.
• Advanced Image Processing: Features 6 selectable colour palettes and 3 dedicated scene modes (Object, Target Outline, and WDR) alongside AI-assisted multi-target distance estimation.
• Continuous Power System: Powered by a replaceable 18650 Li-ion rechargeable battery delivering 8 to 10 hours per cell, with direct charging via 5V DC USB-C.
• Onboard Storage and Streaming: Integrated 32 GB internal memory for recording media, with Wi-Fi and hotspot connectivity for the ThermTec Smart Thermal app.
• Rugged Enclosure: Rated to IP67 waterproof and dustproof standards with an operating temperature window of -20°C to +50°C.

Who is the ThermTec Cyclone 625 Thermal Monocular for?

• Active Stalkers — Weighs just 260 g, providing mobile hunters targeting wild boar, feral deer, and foxes an ultra-compact thermal imaging monocular that avoids kit fatigue on foot.
• Wide-Angle Short-to-Medium Range Scanners — Delivers a broad 30.8 m field of view at 100 m via its 25 mm F1.0 optical system, allowing users to sweep expansive woodlines, scrub, and paddocks quickly under 200 metres.
• Property Surveillance Operators — Combines a 640 × 512 resolution sensor with < 20 mK sensitivity to detect subtle human or vehicular heat signatures across perimeters up to 1,300 metres away.

Less suitable for: Open-field glassing, elevated high-seat observation, or positive target identification beyond 200 to 300 metres, where a narrower-angle thermal monocular featuring a larger 35 mm or 50 mm focal length lens provides the required optical base magnification.
