The Guide TD433L is built for hunters and outdoor users who want thermal performance, distance measurement, and portability in one compact unit. Its 35mm F1.0 lens works with the 400x300 thermal sensor and 50Hz refresh rate to deliver smooth thermal imaging with strong detail recognition at extended distances, including a detection range of up to 1800m (1950yd).

One of the standout features is the integrated laser rangefinder, which gives accurate readings out to 1000m (1090yd) without turning the monocular into a bulky unit. Combined with the fingertip focus roller and ambidextrous control layout, the TD433L stays practical to operate with one hand while moving through rough terrain or scanning from a fixed position.

The upgraded AMOLED display improves image clarity and viewing comfort, particularly during long observation sessions. Built-in recording with audio capture allows you to save footage directly to the 16GB internal storage, while dual-band Wi-Fi and Bluetooth connectivity add flexibility for sharing content or connecting accessories.

With IP67 protection, replaceable 18650 battery power, and up to 10 hours of runtime, the TD433L is designed for demanding field use where reliability matters just as much as image quality.
