The AGM ObservIR LRF 35-384 is a dual-spectrum thermal and digital day/night vision binocular built around a 12-micron VOx uncooled focal plane array delivering 384x288 thermal resolution at a noise equivalent temperature difference (NETD) of less than 15 mK. A secondary 3840x2160 ultra-low-light CMOS optical channel runs alongside the thermal channel, letting you cross-reference heat signatures with visible-detail imagery in a single instrument. A Class 1 eye-safe laser rangefinder reaches targets at up to 1,000 meters with plus-or-minus 1-meter accuracy, a built-in GPS module logs position data, and 64 GB of internal EMMC storage captures video and audio recordings or snapshots on demand. The unit weighs 0.91 kg (2.01 lb), carries an IP67 waterproof rating, and runs up to eight hours on two replaceable 18650 lithium-ion batteries. Four 18650 cells are included in the box.

Who this is for

• Hunters and long-range observers who need to detect, range, and positively identify game or targets in complete darkness or low-contrast daylight conditions from distances out to 1,800 meters.
• Security and surveillance professionals who require a single multi-function unit that logs GPS coordinates, records video evidence, and connects via Wi-Fi hotspot to a companion app without switching between separate devices.
• Search-and-rescue teams operating across a broad temperature window (-20°C to 55°C / -4°F to 131°F) who depend on thermal contrast to locate subjects in dense terrain or adverse weather conditions.

Thermal channel performance

The thermal channel uses a 12-micron VOx uncooled focal plane array with a 384x288 detector resolution and a 50 Hz refresh rate. The F1.0 aperture on the 35 mm objective collects a wide cone of infrared energy, and the sub-15 mK NETD figure means the sensor resolves fine temperature gradients that wider-NETD detectors miss. Thermal magnification runs from 4.0x to 20x with a horizontal field of view of 7.5 degrees at base magnification. Detection range for a 6-foot object reaches 1,800 meters. Four color palettes — Black Hot, White Hot, Red Hot, and Fusion — cover standard observation tasks, and two scene modes (Jungle and Recognition) optimize the image-processing pipeline for specific environments. Flat field correction runs in automatic, manual, or external-correction mode, and a highest-temperature spot tracker highlights heat peaks in the frame automatically.

Digital day/night optical channel

The optical channel pairs a 60 mm F2.2 lens with a 3840x2160 (1/1.8-inch progressive scan) CMOS sensor for an ultra-low-illumination daylight and night-vision view. Optical magnification spans 5.5x to 22x with a horizontal field of view of 7.3 degrees. The built-in 850 nm smart IR illuminator supplements ambient light in darkness, with adjustable power and beam angle. Picture-in-picture mode overlays the optical channel on the thermal view — or vice versa — so you can confirm target detail without leaving the thermal image. The display output runs through a 1920x1080, 0.49-inch OLED panel at 50 FPS, with display mode selectable between Day, Night, and Auto.

Laser rangefinder and navigation

The integrated Class 1 eye-safe laser operates at 905 nm and ranges targets out to 1,000 meters with plus-or-minus 1-meter accuracy. A digital magnetic compass and GPS module work alongside the rangefinder to give bearing and position data in the field. Both GPS coordinates and compass heading can be recorded to the 64 GB onboard EMMC storage alongside video and audio captures. Wi-Fi hotspot connectivity enables live streaming or data transfer to the AGM Connect companion app.

Power and connectivity

Two replaceable 18650 lithium-ion cells power the ObservIR LRF for up to eight hours of continuous operation at 25°C with Wi-Fi, IR illuminator, and LRF switched off. Four 18650 batteries ship in the box along with a dedicated battery charger. A USB Type-C port accepts 5 VDC / 2 A external power for extended or stationary deployments. An auto screen-off function and a standby mode reduce drain during pauses in observation. A tripod adapter is included for fixed-post or vehicle-mount applications.

Build and environmental rating

The housing measures 221 x 142 x 71 mm (8.7 x 5.6 x 2.8 inches) and carries rubber overmolding across the exterior. IP67 certification means it survives full submersion in water to 1-meter depth for 30 minutes and blocks dust ingress entirely. The operating temperature range of -20°C to 55°C (-4°F to 131°F) covers arctic cold and desert heat. Interpupillary distance adjusts from 60 mm to 74 mm, and the diopter adjustment range spans -5 to +3 to accommodate a wide range of visual corrections.

Specifications

Frequently asked questions

Can this binocular be exported outside the United States?

No. The AGM ObservIR LRF 35-384 is subject to US export regulations and is not exportable outside the United States without the appropriate license. By purchasing this product you confirm you are located in the United States and have no intention to export it in violation of US Government regulations.

What is the difference between the thermal channel and the digital day/night channel?

The thermal channel detects infrared heat signatures emitted by objects and people, making it effective regardless of ambient light. The digital day/night CMOS channel captures visible and near-infrared light for detailed image recognition. Picture-in-picture mode lets you view both channels simultaneously, so you can detect a heat signature on thermal and confirm identification with the optical channel without switching modes.

How accurate is the laser rangefinder?

The built-in Class 1 eye-safe laser rangefinder is accurate to plus-or-minus 1 meter at distances up to 1,000 meters. The 905 nm laser wavelength is eye-safe under normal operating conditions.

How long does the battery last and can I use external power?

Up to eight hours of continuous operation at 25°C with Wi-Fi, the IR illuminator, and the laser rangefinder switched off. Activating those features will reduce run time. The USB Type-C port accepts a 5 VDC / 2 A external power supply for stationary or vehicle-mounted use, and the auto screen-off and standby functions extend battery life during breaks in observation.

Is this unit waterproof?

Yes. The ObservIR LRF 35-384 carries an IP67 rating, meaning it withstands temporary full submersion and complete dust ingress protection. It operates across a temperature range of -20°C to 55°C (-4°F to 131°F).

What is included in the box?

The package includes four rechargeable 18650 batteries, a battery charger, a USB cable, a power adapter, a tripod adapter, a quick start guide, a user manual, a lens cloth, and a neck strap.
