When it comes to compact thermal imaging that punches well above its size, the ThermTec Cyclone 625 Thermal Monocular delivers serious performance in a pocket-friendly package. Built around a high-resolution 640x512 thermal sensor with a fine 12µm pixel pitch and an exceptional NETD of less than 20mK, this unit picks up subtle heat signatures with impressive clarity at ranges out to 1,300 metres. Whether you're spotting feral pigs on a night shift, scanning paddocks for pest activity, or simply wanting a capable thermal observer for the field, the Cyclone 625 gives licensed hunters and land managers a genuinely capable tool without the bulk of larger units. At just 260g and designed for confident one-handed operation, it's the kind of thermal monocular you'll actually carry rather than leave in the truck.

ThermTec Cyclone 625 Thermal Monocular Key Features

• Thermal Sensor Resolution: 640x512 with a 12µm pixel pitch delivers dense image detail, giving you sharper, more defined heat signatures compared to lower-resolution sensors - particularly useful when trying to differentiate animals at distance.
• NETD <20mK: Noise Equivalent Temperature Difference below 20 millikelvin means the sensor can resolve extremely subtle temperature variations, making it easier to detect partially obscured or stationary animals in complex terrain.
• Detection Range: Rated to 1,300 metres, making it well-suited to medium-range spotting across open paddocks, scrub edges, and ridgelines.
• Objective Lens: 25mm F1.0 lens with a wide aperture maximises light (infrared energy) collection, contributing to cleaner imagery in demanding conditions.
• AMOLED Display: The 0.39 inch (approximately 1cm) AMOLED screen runs at 1024x768 resolution, offering vivid contrast and sharp image rendering even in bright ambient conditions.
• 50Hz Frame Rate: A 50Hz refresh rate delivers smooth, fluid motion tracking - important when following fast-moving animals or panning across terrain quickly.
• Magnification and Zoom: 1.40x optical magnification with 2.4x digital zoom. The 10.5° x 7.9° field of view keeps situational awareness broad at base magnification.
• AI Calibration and Self-Learning Algorithms: On-board artificial intelligence continuously refines image quality and calibration without requiring manual input, maintaining stable, clear imagery across changing thermal environments.
• Multi-Target Rangefinder: Built-in multi-target distance detection lets you range multiple subjects simultaneously, a practical advantage when assessing a mob of animals or working a large area.
• Heat Track Function: Automatically identifies and tracks the hottest point in the frame, keeping focus on the primary heat source even as it moves through the scene.
• 3-Second Startup: Near-instant power-on means the unit is ready to go the moment you need it - no waiting around in critical spotting situations.
• 3 Image Modes and 6 Colour Palettes: Forest, Target, and Outline modes alongside six selectable colour palettes let you optimise the display for different environments and personal preference.
• Picture-in-Picture (PIP): Displays a magnified inset window within the main field of view, allowing you to inspect a target in detail without losing your wider situational awareness.
• 32GB Internal Memory with Audio Recording: Onboard storage supports photo and video capture, video playback, audio recording, and OSD (on-screen display) recording - useful for documentation during pest management operations.
• Battery Life: Runs on a single replaceable and rechargeable 18650 Li-ion cell for up to 10 hours. A second battery (carried separately) extends total runtime to 20 hours. The unit also supports operation while charging via its USB Type-C port.
• IP67 Waterproof Rating: Fully dustproof and protected against temporary submersion, making it reliable across wet weather and rough field conditions.
• Operating Temperature: Rated from -20°C to +50°C, covering everything from alpine winter conditions to hot inland summers.
• Eye Relief and Exit Pupil: 20mm of eye relief and a 6mm exit pupil make for comfortable, extended viewing, including for users wearing glasses.
• Hotspot Connectivity: Built-in hotspot enables app-based remote control, allowing the unit to be operated or monitored from a connected device.
• Diopter Adjustment: ±5D diopter range accommodates a wide range of eyesight prescriptions for clear, sharp viewing without corrective lenses.

The ThermTec Cyclone 625 represents a well-considered thermal monocular for hunters, pest controllers, and serious field operators who want 640-resolution performance in a genuinely portable, easy-to-operate package. With its AI-assisted imaging, long battery endurance, and comprehensive recording suite, it covers the full range of tasks you'd ask of a modern handheld thermal unit.
