ThermTec Cyclone 625 Thermal Imaging Monocular
Compact Thermal Performance Without Compromise
The ThermTec Cyclone 625 is designed for hunters and outdoor users wanting premium thermal capability in an ultra-lightweight and highly portable platform.
Weighing approximately 260g, the Cyclone 625 delivers serious thermal performance without the bulk typically associated with larger thermal monoculars.
This makes it ideal for:
• Spot-and-stalk hunting
• Bush and timber observation
• Fast scanning
• Mobile hunting setups
• Everyday carry thermal use
Premium 640 Thermal Sensor
At the core of the Cyclone 625 is a premium:
• 640×512 VOx thermal sensor
• 12μm pixel pitch
• NETD <18–20mK thermal sensitivity
This delivers:
• Exceptional thermal detail
• Excellent target separation
• Improved visibility in humidity and poor weather
• Cleaner thermal imaging with reduced background noise
Combined with ThermTec’s AI-enhanced image processing, the result is a smooth and highly refined thermal image in real-world hunting conditions.
Wide Field-of-View 25mm Lens
The Cyclone 625 uses a 25mm F1.0 objective lens, optimised for fast scanning and wider situational awareness.
Compared to larger 50mm thermal systems, the 25mm lens provides:
✔ Wider field of view
✔ Faster target acquisition
✔ Better close-to-mid-range usability
✔ Improved scanning efficiency in timber and scrub
This makes the Cyclone 625 especially effective for:
• Bush hunting
• Dense terrain
• Moving targets
• General observation
Long Detection Capability in a Pocket-Sized Unit
Despite its compact size, the Cyclone 625 still delivers impressive thermal performance with detection ranges up to approximately 1300m.
This allows users to:
• Detect animals at significant distance
• Rapidly scan paddocks and tree lines
• Maintain strong situational awareness
• Carry a lightweight secondary thermal device
AI Calibration & Image Stability
ThermTec’s advanced AI calibration system continuously optimises image quality based on environmental conditions.
Benefits include:
• Smoother image presentation
• Improved target stability
• Reduced calibration interruptions
• Cleaner thermal detail during prolonged use
This creates a more refined user experience compared to many entry-level thermal monoculars.
Ultra-Lightweight Pocket-Sized Design
One of the standout features of the Cyclone 625 is its exceptional portability.
At approximately 260g, it remains one of the lightest premium 640 thermal monoculars currently available.
Benefits include:
• Easy all-day carry
• Reduced fatigue
• Faster one-handed operation
• Pocket-sized portability
This is particularly valuable for hunters covering large distances on foot.
AMOLED Display & User Interface
The Cyclone 625 features a premium:
• 1024×768 AMOLED display
• Fast startup time (~3 seconds)
• Picture-in-picture mode
• Hotspot tracking
• AI distance measurement
These features improve overall usability while maintaining a compact and intuitive interface.
