The Guide TE419S Thermal Monocular combines high-sensitivity thermal imaging with a compact, easy-to-use handheld design. Its 400 × 300 @ 12μm thermal detector and NETD sensitivity of less than 15mK reveal fine temperature differences, providing clear and detailed imagery in darkness, fog and other challenging conditions.

Equipped with a 19mm objective lens, 1.4× base magnification and a detection range of up to 1,000 metres, the TE419S is well suited to hunting, wildlife observation, property surveillance and general outdoor use. Its wide field of view also makes it particularly effective for scanning at shorter distances and in wooded environments.

Guide’s advanced APEXVISION S1 image-processing system further improves image clarity, motion smoothness and long-range detail. The built-in rechargeable battery provides up to five hours of operation, while 20W fast charging can provide approximately one hour of use from a 10-minute charge.
