HIKMICRO HABROK 4K HH35L 2.0
HIKMICRO HABROK 4K HH35L 2.0 multi-spectrum binoculars combine a 384 × 288 thermal detector, <15 mK sensitivity and 35 mm F1.0 lens with 4K digital day and night vision. Thermal detection up to 1,800 m, a 1,000 m laser rangefinder, interchangeable infrared illuminators and dual-channel image stabilisation support detailed wildlife observation and hunting from daylight to darkness.
Series Overview
4K Digital Imaging for Day and Night Observation
The HH35L 2.0 combines a 3840 × 2160 CMOS sensor with a 60 mm F2.2 digital lens and 5.5–22× magnification. Switch between Day, Night and Auto modes for changing light conditions, with infrared illumination supporting digital observation after dark.
Interchangeable 850 nm and 940 nm Infrared Illuminators
Adapt digital night viewing with replaceable 850 nm and 940 nm infrared illuminators. The HH35L 2.0 uses 940 nm as standard and supports an interchangeable 850 nm illuminator. Smart IR and a stated digital night-viewing range of up to 400 m support observation in darkness.
Rear Focus and Dedicated Thermal/Digital Switching
A rear focus wheel and dedicated Thermal/Digital switch keep essential controls within easy reach. Scan for heat in thermal mode, then switch to the digital channel for a closer look without changing devices.
Sub-15 mK Thermal Sensitivity with Shutterless Viewing
A 384 × 288 thermal detector, 12 μm pixel pitch and 35 mm F1.0 lens provide thermal detection up to 1,800 m. Sensitivity below 15 mK helps reveal subtle temperature differences, while a 50 Hz frame rate and HIKMICRO Shutterless Image System support continuous observation without routine shutter-calibration interruptions.
Built-in 1,000 m Laser Rangefinder
The integrated Class 1 laser rangefinder measures distances from 10 m to 1,000 m with ±1 m accuracy. Check subject distance directly through the binoculars without carrying a separate rangefinder. Laser ranging is distinct from the thermal channel’s detection range of up to 1,800 m.
Compact, Rugged Design for Field Observation
Weighing 900 g without batteries, the HH35L 2.0 combines thermal imaging, digital day and night vision, infrared illumination and laser ranging in one binocular. IP67 protection and an operating temperature range of −30°C to +55°C support use in demanding outdoor conditions.
50 Hz Thermal Imaging, Zoom Pro and SyncPro
The thermal channel operates at 50 Hz. Zoom Pro enhances thermal detail during magnification, while SyncPro supports smoother image presentation. Together with HSIS shutterless imaging, these technologies help maintain a continuous view when scanning and following moving subjects.
0.49-inch Full HD OLED Display
A 0.49-inch 1920 × 1080 OLED display provides a detailed view of thermal and digital images. Adjust interpupillary distance from 60–74 mm and dioptres from −5 D to +3 D to suit your eyes, with adjustable brightness, contrast and warm or cool image tones.
Picture-in-Picture Viewing
Combine a thermal main view with a digital inset, or a digital main view with a thermal inset. Picture-in-Picture places an enlarged central view at the upper centre of the display. With PIP enabled, zoom adjustment changes the inset rather than the main view.
Integrated Ballistic Calculation
The built-in ballistic calculator uses the measured distance and an entered ammunition profile to provide adjustment guidance for a separate, already-zeroed riflescope. The HH35L 2.0 remains a handheld observation binocular. Continuous laser ranging is unavailable while ballistic calculation is enabled.
Replaceable Batteries for Extended Observation
Replaceable rechargeable batteries provide at least 6.5 hours of operation at 25°C with the hotspot and laser rangefinder enabled. USB-C supports external power and direct charging, while standby mode helps conserve power between observations. Actual runtime varies with temperature, settings and use.
Local Album and HIKMICRO Sight App
Capture photos, video and audio to the built-in 64 GB storage, then review recordings in the local album. Connect to the HIKMICRO Sight app to transfer observations to your smartphone for convenient viewing and sharing.
Steadier Zoom with Dual-Channel Image Stabilisation
Electronic image stabilisation supports both thermal and digital channels from 2× digital zoom, helping reduce visible hand movement during magnified observation. Thermal magnification spans 4–20×, while the digital channel offers 5.5–22×. A 1920 × 1080 display presents both views through the binocular eyepieces.
More Advantages
Dual-channel focus, Picture-in-Picture, green and yellow digital night-viewing modes and IP67 protection complete the HABROK 4K HH35L 2.0 feature set. The operating temperature range is −30°C to +55°C.

| Is the thermal image 4K? | No. The thermal sensor is 384 × 288; the separate digital sensor is 3840 × 2160. |
| Does it offer the same magnification in both channels? | No. Thermal is 4–20×; digital is 5.5–22×. |
| Is 1,800 m the laser ranging distance? | No. 1,800 m is the thermal detection specification; the laser rangefinder is specified for 10–1,000 m. |
| Does it need two batteries or four? | Two are required for operation. The standard package contains four, providing a spare pair. |
| Can the batteries charge inside the binocular? | Yes, using USB-C with the batteries installed; the supplied external charger is another option. |
| Can thermal and digital views be seen together? | Yes. Picture-in-Picture can show a thermal main view with a digital inset, or a digital main view with a thermal inset. |
