Merger Duo multispectral binoculars are made with the external design of classic daytime binoculars and provide comfortable viewing with both eyes.

The device allows you to quickly switch between thermal imaging and monochrome night digital channels, as well as supports PiP (Picture in Picture) multispectral mode, when the image of one channel is displayed in the main window, and the second – in the PiP “window”.

Merger Duo devices do not require an external light source and are not affected by bright light exposure in thermal imaging mode.

A thermal imaging channel can be used both at night-time and during the day in adverse weather conditions (fog, smog, rain), as well as having the obstacles (branches, tall grass, dense bushes etc.) hindering the target detection.

In black and white digital channel, the device allows observation both day and night. In night conditions (absence of starlight, moonlight), it is recommended to use an infrared illuminator.

Merger Duo binoculars are perfectly suited for night hunting, observation, trail orientation, identifying hazards, rescue operations, etc

2. When there is no removable battery in the device, only one icon for the built-in battery displays in white in the status bar.
3. When both batteries are fully charged, the device is powered by the removable battery. If there is low removable battery level, the device will switch to the built-in battery.
4. Battery charge level is displayed in % above the icon in the status bar while charging.
5. It is possible to replace the removable battery even while the device is on.

Attention!  When installing a removable battery with a sufficient charge level, the device will automatically switch to it.

Power can be supplied from an external source such as a 5 V power bank.

1. Connect the external power supply to the USB Type-C port (19) of the device.
2. The device switches to external power source, while built-in Battery Pack and removable Battery Pack APS3 will gradually recharge.
3. The display will show the battery icon with charge level as a percentage.
4. If the device is powered by an external power supply, but the APS3 battery is not connected, only the built-in battery will be charged.
5. When the external power supply is disconnected, the device switches to the internal battery pack without powering off.

Warning! Charging the built-in battery and the APS3 battery from the power bank at an external temperature below 0 °C (32 °F) can reduce the battery life. When using external power, connect the Power Bank to the device after it has been turned on and working for several minutes.

1. Open the rubber plug of the USB type-C connector (19) of the device.

• When the device approaches the face, the displays will automatically turn on.
• The proximity sensor can be disabled/enabled in the “General settings” section of the main menu.

Observation conditions: time of day, weather, different observation objects affect the image quality. Custom settings for brightness, display contrast as well as the function of adjusting the microbolometer sensitivity level will help to achieve the desired quality in a particular situation.​

Warning! Never point the lens at intensive energy sources such as laser radiation emitting devices or the sun. It can damage electronic components in the device. The warranty does not cover damage arising from failure to comply with operating instructions.

The carrying case comes with 2 straps:

1. 2-point strap for carrying the case on your shoulder.

2. 4-point strap for comfortable carrying of the case on the chest during intensive movement and uniform weight distribution.

The binoculars are equipped with safety straps with carabiners that can be hooked onto the rings on the 4-point strap or on the neck strap. The length of the safety belts can be adjusted.

The device has 3 image modes: thermal imaging, digital and multispectral PiP mode.

• Quickly switch between thermal and digital modes by briefly pressing the MODE (6) button.
• Activate the multispectral PiP mode by a long press of the MODE (6) button.
• In the multispectral PiP mode, the image channels in the PiP window are switched by briefly pressing the MODE (6) button.

Thermal Imaging Mode

The device displays an image from a thermal imaging microbolometer when using the thermal imaging mode.

This mode allows you to use the device both at night-time and during the day in adverse weather conditions (fog, snow, haze) when there are obstacles (branches, tall grass, dense bushes etc.) that make it difficult to detect the target.

In thermal imaging mode, the riflescope does not need an external light source and is resistant to high light levels.

Digital Mode

In digital mode, the device generates a black and white image from a digital sensor.

In this mode, the device allows observation both day and night. In night conditions (absence of starlight, moonlight), it is recommended to use an infrared illuminator ith a wavelength of 940 nm.

Multispectral PiP

,

In the multispectral PiP mode, the image of one channel is displayed in the main window, and the image of the second channel is displayed in the PiP window.

In this mode, digital zoom is applied only to the PiP window. The magnification in the main window is set to base.

Merger Duo binoculars feature video recording and photography of the image being ranged to the internal memory card.

Before using the photo and video functions, read the Date and Time subsections of the General Settings section.

Built-in recorder operates in two modes:

• Photo (photography; the icon  is displayed in the upper left corner of the image).

• Video (video recording; the icon is displayed in the upper left corner of the image, the total remaining recording time is given taking into account the current resolution in the HH:MM format (hours:minutes).

Switching between the operating modes of the video recorder is done by long pressing the REC (5) button. Switching between the modes is cyclical (Video–> Photo–> Video…).

Photo mode. Capturing an image

1. Switch to the Photo mode with a long press of the REC (5) button.

2. Press the REC (5) button briefly to capture a photo. The icon  flashes – the photo file is being saved to the built-in SD card.

Video mode. Recording a video

1. Switch to the Video mode with a long press of the REC (5) button.

2. Press the REC (5) button briefly to start video recording.

3. When the video recording starts, the icon  will disappear, instead of it the REC icon as well as the video recording timer displayed in the MM:SS (minutes:seconds) format will appear .

4. Pause/continue recording by briefly pressing the REC (5) button.

5. Press and hold the REC (5) button to stop video recording.

Video files are stored in the built-in memory card:

• After turning off the video recording;
• Upon powering the device off if recording was on;
• When the memory card is overfilled during recording (Memory Full message appears).

Notes:

• You can enter and navigate the menu during video recording.
• Recorded videos and photos are saved to the built-in memory card of the device in the format img_xxx. jpg (for photos); video_xxx. mp4 (for video).
• Videos are recorded in clips with a maximum duration of 5 minutes. The number of recorded files is limited by the capacity of unit’s internal memory and video compression ratio.
• Regularly check free memory within the built-in memory card and move the footage to other storage media to free up the memory card space.
• In case of a memory card error, you can use the format function in the General Settings section of the main menu.
• When the Display Off function is activated, video recording continues to run in the background.

The device allows you to quickly increase the basic magnification (please refer to the Magnification line in the Specificationstable) by 2, 4 or 8 times.

• To operate the discrete digital zoom, press successively the UP/ZOOM (7) button.
• The digital zoom will not be saved after the device is re-started.

Note: the magnification value is reset to the base value when the device is switched off.

Available in thermal imaging and digital mode

PiP (“Picture in Picture”) allows you to see a zoomed image simultaneously with the main image in a dedicated window.
