ThermTec Cyclone Thermal Imaging Monocular – 315, 325 & 625

Compact Thermal Performance | Exceptional Image Clarity | Intelligent AI Technology

The ThermTec Cyclone Series combines impressive thermal imaging performance, advanced technology and a lightweight, pocket-sized design to deliver outstanding value for money. Available in three models – the Cyclone 315, Cyclone 325 and Cyclone 625 – the range provides a versatile thermal imaging solution for wildlife observation, field sports and outdoor exploration.

Featuring highly sensitive thermal sensors with a NETD of 20mK, the Cyclone Series detects subtle temperature differences, delivering clear, detailed thermal imagery even in challenging conditions. With a choice of 384 × 288 or 640 × 512 thermal sensor resolutions, the range offers excellent detection capabilities to suit different observation requirements and budgets.

The high-resolution 1024 × 768 AMOLED display, combined with a smooth 50Hz refresh rate, ensures crisp, fluid viewing when observing moving wildlife. ThermTec's intelligent AI Calibration technology continuously optimises image quality, providing stable thermal imagery and improved detail recognition across changing environments.

Designed with portability and convenience in mind, the Cyclone Series features a compact, ergonomic housing weighing as little as 255g without the battery. Its intuitive button layout and convenient one-handed focusing system allow comfortable operation for both left-handed and right-handed users.

The series also features AI-assisted distance measurement, helping users estimate distances without the need for a separate laser rangefinder. With six thermal colour palettes and three specialised image modes – Forest, Target and Outline – users can customise their viewing experience to suit different environments and observation conditions.

Powered by replaceable and rechargeable 18650 lithium-ion batteries, the Cyclone Series offers extended operation of up to 10 hours per battery on selected models. With two batteries supplied, the 315 and 325 models can provide up to 20 hours of combined operating time, making them ideal for extended outdoor sessions.

With 32GB internal storage, photo and video recording, Wi-Fi connectivity, picture-in-picture functionality and robust IP67-rated construction, the Cyclone Series offers an impressive combination of advanced features, practical design and affordability.
