Description
Customer Reviews

ThermTec Cyclone 325 is a compact and lightweight handheld thermal imaging monocular for short and medium-range observations. Features a NETD <20mK detector that delivers excellent image quality. AI self-learning algorithms that provide increasingly stable target image quality. With advanced features such as multi-target ranging, 20-hour battery life, 3-second fast startup, etc., it is an excellent entry-level choice to explore the world of thermal imaging.

Key Features & Capabilities

Here are the main capabilities that define the Cyclone 325:

High sensitivity & detector: Uses a 384×288 pixel sensor (VOx microbolometer) with NETD < 20 mK. This means it can discern small temperature differences, which improves clarity in challenging thermal conditions.
Optics and magnification: It has a 25 mm objective lens (F/1.0) with optical magnification around 2.4× and digital zoom up to 4×.
Display: 0.39 AMOLED screen, 1024×768 resolution. Good eye relief, diopter correction (±5D) to adjust sharpness for different users.
Detection Range: Can detect a human-sized target at distances up to around 1,300 meters under favorable conditions.
Battery & Power: Powered by a single replaceable/rechargeable 18650 Li-ion battery, with around 10 hours of runtime. With two batteries, there are claims of up to 20 hours in some usage scenarios.
Durability & Environment: Built to IP67 standard (dust & water resistant), with operating temperatures from -20 °C to +50 °C. T

What Sets It Apart

Here are some attributes that make the Cyclone 325 attractive, especially compared with basic/entry thermal monoculars:

The NETD < 20 mK rating gives it strong performance in detecting subtle heat variations (e.g. in twilight, mist, or light foliage).
The AI enhancements: It includes AI-driven features like multi-target ranging (measuring distance to several heat sources automatically) and other algorithms to improve image stability.
Display & user modes: Multiple color palettes, image/display modes (e.g. forest, target, outline) allow tailoring the view based on conditions.
Portability + ruggedness: Though feature-rich, its weight (˜ 260-261 g without battery) and rugged IP67 enclosure mean it’s usable in field conditions without big compromises.

Who It’s For / Use-Cases

The Cyclone 325 is suited for users who need solid thermal imaging without moving to large, expensive systems. Some use-cases include:

Wildlife observation or game scouting, especially at dawn/dusk or when visibility is low.
Search & rescue operations, or anyone needing to detect heat signatures at medium distances.
Surveillance, security, and outdoor monitoring.
Aerospace outdoors / hiking enthusiasts wanting to see in challenging conditions.

Cyclone 315 vs Cyclone 325: Spec Comparison & Trade-Offs

Feature	Cyclone 315	Cyclone 325
Thermal Sensor / Detector	384×288, 12µm	384×288, 12µm
NETD (Thermal Sensitivity)	=20mK	=20mK
Frame Rate	50Hz	50Hz
Objective Lens / Focal Length	15mm, F1.0	25mm, F1.0
Field of View (FOV)	17.5° × 13.1° (~30.7m × 23.0m at 100m)	10.5° × 7.9° (~18.4m × 13.8m at 100m)
Magnification / Zoom	1.4× optical + digital zoom (1× / 2× / 4×)	2.4× optical + digital zoom (1× / 2× / 4×)
Detection / Identification Range	Up to ~750m (human-sized target)	Up to ~1,300m (detection)
Display / Eyepiece	AMOLED 0.39, 1024×768 px; diopter ±5; eye relief 20mm	Same as 315
Battery / Power	Single 18650 Li-ion (~10 hrs), dual (~20 hrs), supports use while charging	Same as 315
Weight (without battery)	~255g	~261g
Dimensions	139 × 76 × 54 mm	135 × 76 × 54 mm
Other Features / Modes	AI multi-target ranging, Forest/Target/Outline modes, 6 color palettes, PIP, recording, 32GB storage, IP67, startup ~3s	Same as 315

Trade-Offs & Observations:

Cyclone 325 gains reach and magnification with the longer lens but has a narrower field of view.
Cyclone 315 has a wider FOV, better for general scanning of immediate surroundings.
Weight and ergonomics are very similar; choice mainly depends on desired range vs coverage.

Cyclone 325 vs Competing Models

Strengths of Cyclone 325:

High sensitivity (=20mK) helps detect low-contrast thermal scenes.
AI-based multi-target ranging and imaging modes improve usability in the field.
Compact, lightweight, and robust (IP67).
Flexible battery strategy (modular 18650, use-while-charging).

Potential Limitations:

384×288 sensor is solid but lower resolution than 640×512 or higher models.
Narrower FOV can make close inspection or wide scanning less comfortable.
No optical zoom; only digital zoom.
Detection range is good, but real-world identification depends on atmospheric conditions, contrast, and target size.

Who It’s For / Use-Cases

Wildlife observation or game scouting at dawn/dusk or low visibility.
Search & rescue operations or heat-source detection at medium distances.
Surveillance, security, and outdoor monitoring.
Outdoor enthusiasts wanting thermal vision in challenging conditions.
