Product Overview

The Guide TD435LS Thermal Monocular with LRF is built for Aussie paddocks, scrub and long nights on the ute. Running a 400×300 VOx sensor with ApexVision processing, it gives you crisp, high-contrast heat signatures even when the air is warm and the background is busy. The 35mm F1.0 lens, 3.26–13.04x magnification and 1800m detection range mean you can pick up foxes, pigs and rabbits early, then use the integrated 1200m laser rangefinder to know exactly how far they are. In the hand, the TD435LS is all about practical field use. The compact housing, ambidextrous grip and focusing roller make true one-handed operation easy, whether you’re opening gates or working a spotlight with the other hand. A 0.49" AMOLED display keeps the image sharp, while the IP67 rating and up to 10–12 hours from a single replaceable 18650 battery let you stay out through dust, drizzle and cold without worrying about gear. Built-in Wi‑Fi, onboard recording and multiple colour palettes round it out as a serious, no-nonsense thermal spotter for Australian hunting and farm work.

Features

Integrated laser rangefinder for precise distance measurement up to 1200 m

The built-in laser rangefinder lets you instantly gauge the distance to animals, landmarks, or targets out to 1200 metres. This improves shot placement, navigation, and situational awareness, especially in open paddocks or mixed terrain. Having ranging integrated into the monocular means fewer devices to carry and faster, more confident decisions in the field.

High-sensitivity 400×300 @ 12µm VOx sensor with ≤15 mK NETD

The TD435LS uses a 400×300 VOx detector with 12µm pixels and sensitivity down to 15 mK, allowing it to pick up very small temperature differences. In real-world terms, this means clearer separation between animals and background, even on warm nights with low thermal contrast. Hunters and landowners can detect foxes, rabbits, and other pests earlier and identify them more reliably.

ApexVision imaging platform with smooth 50 Hz refresh

Built on the ApexVision S1 architecture, the TD435LS combines advanced processing with a fast 50 Hz frame rate for smooth, ghost-free motion. AI-assisted algorithms enhance edges and balance contrast in complex bush or scrub, helping you track moving animals without blur or lag. The result is a more natural, comfortable viewing experience during long scanning sessions.

0.49" AMOLED display for sharp, comfortable viewing

A 0.49-inch AMOLED screen with 1440×1080 resolution delivers crisp, detailed thermal images. The high pixel density makes it easier to distinguish animal shapes, read menus, and judge terrain features in the dark. Combined with multiple colour palettes, it gives users flexibility to choose the view that best suits their eyes and conditions.

Ergonomic one-handed design with focusing roller and long battery life

The symmetrical housing, side hand strap, and fingertip focusing roller are designed for comfortable one-handed use with either hand. A replaceable 18650 battery provides up to 10–12 hours of operation, so you can cover long nights without worrying about power. IP67 encapsulation adds confidence in dusty, wet, or muddy environments common in Australian hunting and farm work.
