• Hunters and observers needing greater thermal detail and detection range than the 25‑256 provides
• Users who want a versatile day/night binocular with integrated rangefinder, GPS and compass
• Those who value long runtime (~9.5 h) from dual 18650 batteries

• Buyers seeking the highest resolution; the 35‑640 model will offer 640×512 resolution
• People who want an ultra‑lightweight monocular rather than a 0.91 kg binocular
• Shooters looking for a weapon‑mounted optic – this is a handheld device

Compared to the ObservIR 25‑256, the 35‑384’s thermal channel jumps from 256×192 to 384×288 resolution, delivering clearer images and extending detection range from ~1.2 km to ~1.8 km. It also increases thermal magnification from 4.5×/9×/18× to 4×/10×/20×. Battery life is slightly longer (about 9.5 h). All other features – 4K digital channel, IR illuminator, rangefinder, GPS, 64 GB memory and IP67 rating – remain consistent. The forthcoming 35‑640 version will further improve thermal resolution and range but may reduce runtime.

The 35‑384 offers a higher‑resolution thermal sensor and longer detection range than the 25‑256 while preserving the same 4K digital module and general feature set. Battery life increases from ~8 to ~9.5 hours. A future 35‑640 version will further improve resolution.

Users report that the 35‑384 provides noticeably clearer thermal images than the 25‑256, making it easier to identify animals at ~500–800 metres. The combination of thermal and digital channels allows quick confirmation of targets and reading of signs or tracks. Battery life of about 9.5 hours is sufficient for most night‑time operations. The binocular is heavier than a monocular but offers the benefit of stereoscopic viewing and integrated rangefinding and navigation tools.

• 384×288 VOx thermal sensor with <15 mK sensitivity
• 35 mm f/1.0 thermal lens; 4×/10×/20× thermal magnification
• 4K digital channel with 60 mm f/2.2 lens; 5.5×/11×/22× magnification
• Detection range ≈1.8 km; integrated eye‑safe 1,000 m laser rangefinder
• Built‑in IR illuminator, GPS, digital compass and picture‑in‑picture
• Records video/audio to 64 GB memory; Wi‑Fi and standby mode
• Runs up to 9.5 h on two 18650 batteries; IP67 waterproof with 5‑year warranty

AGM’s ObservIR LRF 35‑384 elevates the dual‑channel binocular concept with a higher‑resolution thermal sensor. The 384×288 VOx detector, coupled with a 35 mm f/1.0 lens, offers thermal magnification of 4×, 10× and 20×, enabling clearer identification of animals and objects at distance. The complementary 4K digital channel with a 60 mm f/2.2 lens delivers crisp colour or monochrome images during daylight and low‑light conditions. A built‑in eye‑safe laser rangefinder measures distances up to 1,000 m, while GPS and a digital compass assist with navigation.

An IR illuminator extends the digital channel’s night performance. With 64 GB of storage, the binocular records video and audio with optional picture‑in‑picture overlays. Two rechargeable 18650 batteries provide up to 9.5 hours of operation, and the unit is sealed to IP67 standards.

At about 0.91 kg, it’s heavier than monocular options but offers stereoscopic viewing and integrated ranging and navigation tools, making it ideal for serious observation and hunting tasks.
