Product detail
Thermal Observation with a 35 mm F1.0 Lens The ThermTec Cyclops 335 SE is a handheld thermal imaging monocular for observation, night hunting, rescue operations, hiking and travel.

The device starts within three seconds and uses quiet button controls with an intuitive interface, helping you move from carrying to observation without a complicated setup.
384 x 288 Thermal Imaging System The uncooled microbolometer has a 384 x 288 resolution, 12 micrometre pixel pitch, 20 mK NETD at 300 K and an 8-14 micrometre spectral range.
Buyer guidance
Choose it for the right job
Plain, practical checks for UK buyers comparing thermal, night vision and rifle optics before paying.
Close pest control
Rats around buildings or feeders are usually short range. Prioritise a clear image, quick start-up and easy handheld handling before chasing maximum distance.
Rabbit and fox work
For rabbits and foxes, check realistic identification distance, LRF needs and battery life. A higher sensor and suitable lens matter more than bold marketing range claims.
Mounting check
If it is going on a rifle, confirm the tube, mount or rail fit before payment. Common checks include 30 mm / 34 mm rings, Picatinny or dovetail fittings and eye relief.
Compatibility checklist
Useful details to confirm before payment, especially for rifle-mounted optics and add-ons.
- Intended use: rats, rabbits, foxes, target shooting or observation
- Typical distance: under 50 m, 50-150 m, 150-300 m or longer fields
- Mounting: 30 mm / 34 mm tube, Picatinny, Weaver, dovetail, clip-on or handheld
- Accessories: IR illuminator, battery pack, charger, rail, case or tripod
