Product Overview

The Thermtec Ventus 335L Multispectral Binoculars are built for hunters who need reliable target identification across mixed bush, paddocks and timbered country. Combining a sensitive 384×288 thermal sensor with a 4K CMOS day/night channel, the Ventus 335L lets you quickly pick up heat signatures, then switch to crisp digital detail to confirm species, antler and background before you commit to the shot.

A 5‑in‑1 multispectral system, integrated laser rangefinder and hybrid picture‑in‑picture view give you thermal and digital images at the same time, so you stay fully aware of what’s happening around the animal. EIS image stabilisation and ThermTec AI Calibration keep the picture steady and clear under magnification, while the ergonomic dual focus wheels and rubberised chassis make long glassing sessions from the ute, tripod or hilltop far less fatiguing.

With an 1800m thermal detection range, up to 7hr battery life from two replaceable 18650 cells, and IP67 weather protection, the Ventus 335L is ready for serious night work in Australian conditions. Whether you’re culling on broadacre, chasing pigs in the scrub or checking mobs after dark, it delivers the situational awareness and confidence you need to hunt safely and effectively.

Key Features

• 5-in-1 integrated vision system combines thermal imaging, digital day/night viewing, IR illumination, binocular optics and laser rangefinding, so you can carry one device instead of multiple tools.
• 384×288 thermal sensor with NETD <15mK delivers high-contrast heat signatures, helping you detect game and people clearly in fog, rain or complete darkness.
• 4K UHD 3840×2160 CMOS sensor paired with a 50mm F1.4 lens provides sharp daylight and night-vision detail, improving target identification and shot decisions.
• Exclusive Hybrid Picture-in-Picture display lets you view thermal and digital channels simultaneously, giving you both fast detection and precise identification in one glance.
• EIS image stabilisation and ThermTec AI Calibration keep the image smooth and reduce freezing, making long observation sessions more comfortable and less fatiguing.
• Integrated laser rangefinder with precision up to 1000m allows accurate distance measurement, supporting ethical shooting and better situational awareness.
• Long detection range up to 1800m enables early spotting of animals or people across open fields, clearcuts or valleys, improving scouting efficiency.
• Dual-band IR illuminator (850nm / 940nm) optimises night vision performance and lets you choose between maximum reach or more discreet illumination.
• Ergonomic, rubber-coated housing with dual focus wheels and widely adjustable eyepieces offers secure grip and one-handed control, even with gloves in wet or cold conditions.
• Two replaceable 18650 batteries provide up to 7 hours of runtime, and the IP67-rated construction withstands harsh weather, ensuring reliable operation on extended hunts or search missions.
