The GUIDE TD Gen3 LRF series represents the most advanced evolution within the brand's range of handheld thermal monoculars. Designed to offer precise detection, integrated laser ranging, and long battery life, they combine state-of-the-art VOx sensor technology with an ergonomic, rugged design.
These monoculars incorporate a long-range laser rangefinder, a high-definition AMOLED display, multimedia recording functions, and wireless connectivity, while maintaining a compact, lightweight format that is easy to operate with one hand. They are ideal for hunting, surveillance, rescue, or tactical use, even in extreme conditions of darkness, fog, or rain.
The TD433L, TD633L, and TD653L models share the same technological foundation, differing in sensor resolution, lens, and detection range, thus covering all needs from short-distance tracking to professional long-range observation.
Main features
High-performance thermal sensor
12 µm VOx sensors with resolutions of up to 640×512 px and NETD ≤ 25 mK sensitivity, capable of detecting minimal thermal differences to provide clear and detailed images in any environment.
Integrated laser rangefinder
Precision LRF system with a range of up to 1,000 m, allowing you to measure distances without taking your eye off the eyepiece, with great reading stability.
Advanced image processing
Incorporating SuperIR and DDE (Digital Detail Enhancement) algorithms, which optimize contrast, eliminate thermal noise, and improve contours to easily distinguish the target.
High-definition AMOLED display
0.39" AMOLED panel with 1,280×960 px resolution, offering fluid, lag-free viewing with deep blacks and excellent contrast in any lighting condition.
