GUIDE TD435LS LRF Thermal Monocular 400x300

The GUIDE TD435LS is GUIDE's compact 400×300 thermal monocular built around the new APEX VISION infrared imaging system — a significant step forward in AI-powered thermal performance that delivers sharper target detail, cleaner heat separation, and more reliable imagery across a wider range of field conditions than previous generation devices. Powered by a 400×300 thermal sensor with NETD <15mK, a 35mm F1.0 lens, and detection out to 1,800 metres, the TD435LS delivers the full APEX VISION experience in a lightweight, accessible package. Add an integrated 1,200m laser rangefinder and 10-hour battery life — and the TD435LS makes a compelling case as the most practical entry point into GUIDE's premium thermal lineup for Australian hunters who need a reliable spotting and ranging tool without the weight or cost of a 640-sensor device.
