The Guide TD633L Handheld Thermal Monocular is built for users who want detailed thermal imaging, practical rangefinding capability, and straightforward handling in the field. Its 640x512 thermal sensor paired with a 35mm F1.0 lens delivers sharp thermal detail across changing terrain and low-visibility conditions, while the 50Hz refresh rate helps keep movement smooth during scanning or tracking.

A built-in 1000m laser rangefinder gives quick distance readings without adding extra gear to carry. The compact symmetrical housing keeps the monocular comfortable to use with either hand, and the fingertip focus roller allows fast fine adjustments without taking your attention away from what you are viewing. It is the kind of control system that becomes more useful the longer you spend behind the optic.

The upgraded 1280x960 AMOLED display improves image clarity and viewing comfort during extended sessions, especially when working through changing weather or scanning over longer distances. Multiple colour palettes let you tailor the image to conditions and personal preference.

Recording functions are built in, allowing photo, video, and audio capture directly to the internal 32GB storage. Dual-band Wi-Fi and Bluetooth support easier sharing and device connectivity when needed. The replaceable 18650 battery provides up to 10 hours of runtime, helping reduce interruptions during long evenings outdoors.

With IP67 waterproof protection and a lightweight 376g body, the TD633L balances portability with serious thermal performance. A strong option for users who want a compact handheld thermal monocular with integrated rangefinding and modern recording capability without carrying a larger dedicated system.
