The HIKMICRO HABROK 4K LRF HH35L 2.0 thermal/digital binoculars combine several observation modes in a single high-tech device: thermal imaging for rapid detection of heat-emitting objects, a 4K digital channel for detailed day and night observation, interchangeable 850 nm and 940 nm IR illuminators for operation in complete darkness, and a built-in laser rangefinder for measuring distances up to 1,000 metres.
The HABROK 4K 2.0 version builds on this concept with a sensitivity of NETD <15 mK, a refresh rate of 50 Hz, HSIS technology, electronic image stabilisation and a new control system with a separate switch between the thermal and digital channels. The focus wheel has been moved to the rear of the body so that mode switching and focusing can be carried out quickly and conveniently with one hand.
The HH35L 2.0 binoculars are designed for situations where simply detecting game is not enough. The thermal channel helps to scan the terrain and locate heat-emitting objects, the 4K channel allows for a more detailed view of the scene, and the laser rangefinder provides information on the actual distance. This means that the various stages of observation can be carried out using a single device.

What has been improved in the HIKMICRO HABROK 4K 2.0?
The second generation of the HABROK 4K has been developed not only with improvements to the image quality, but also with changes to the controls and the way the binoculars are used in the field.
A dedicated switch between the thermal and digital channels
The HABROK 4K 2.0 features a dedicated Thermal/Digital Switcher. Rather than switching between the two channels interrupting the observation process, the switch can be made quickly when you first spot a target via the thermal image and then wish to examine it through the 4K digital channel.
Rear-mounted focusing mechanism
The focus wheel is located at the rear of the body and allows for more natural one-handed operation. This design follows the logic of traditional binoculars but has been adapted for use with two different observation channels.
50 Hz for smoother tracking
The 50 Hz refresh rate ensures a smoother image when the observed object is moving or when scanning the terrain quickly. This is particularly useful when tracking moving game.
Stabilisation in both channels
The updated electronic stabilisation algorithms work with both the thermal and digital images. They minimise visible shake during handheld observation, particularly when using higher magnification.
Enhanced infrared illumination
The improved IR system provides clearer infrared illumination when operating in complete darkness. The kit includes two interchangeable illuminators – 850 nm and 940 nm – allowing the configuration to be adapted to the specific situation.
Advantages of the Habrok 4K HH35L binoculars
Thermal channel with NETD <15 mK
The 384 × 288 sensor with a pixel size of 12 μm and sensitivity below 15 mK allows small temperature differences to be distinguished. This aids in the detection and identification of thermal targets in fog, low light and amongst vegetation.
HSIS – observation without the typical interruptions during calibration
The HSIS system is designed to maintain a virtually uninterrupted thermal image. With traditional thermal systems, calibration can briefly interrupt the image, whilst HSIS minimises these interruptions – a key advantage when searching for and tracking moving game.
4K imaging during the day, at dusk and at night
The digital channel utilises a 1/1.8" Progressive Scan CMOS sensor with a resolution of 3840 × 2160 pixels. It provides a colourful and detailed image during the day and maintains a high level of detail as natural light diminishes.
850 nm and 940 nm – two IR illuminators for different situations
In complete darkness, the included interchangeable IR illuminators can be used. The 850 nm illuminator is designed for a longer operating range, whilst the 940 nm illuminator offers more discreet infrared illumination. This means you do not need to choose between the two options at the time of purchase – both are included in the kit.
Zoom Pro and free zoom control
Zoom Pro helps preserve detail when zooming, and the user can select their preferred zoom step – 2×, 3×, 4× or 5×. This allows the control behaviour to be adapted to suit the observation method.
Built-in ballistic calculation
HABROK 4K 2.0 also features an internal ballistic calculation function. Once the profile of the ammunition being used has been entered and the distance measured, the system can calculate the number of clicks required to adjust the optical sight.
This means that distance measurement and ballistic information can be obtained in a single operation, without the need for separate calculations in the field.
Laser rangefinder up to 1,000 metres
The HIKMICRO HABROK 4K HH35L 2.0 features an integrated laser rangefinder, which allows the distance to the observed object to be determined directly through the binoculars. The maximum measuring range is 1,000 metres, the minimum distance is 10 metres, and the stated accuracy is ±1 metre.
