SYMBION LRF DXT50 Manual

Symbion LRF multispectral binoculars are high-tech devices designed for various applications, such as hunting, search and rescue operations, nature conservation, wildlife observation, and active tourism.

Symbion LRF binoculars allow you to quickly switch between thermal imaging and digital channels. The digital channel can be used in both color and black-and-white modes. There is support for the Duo multispectral mode, where the image from one channel is displayed in the main window and the image from the second channel is displayed in a PiP (Picture in Picture) window.

The thermal imaging channel can be used both at night and during the day, including in difficult weather conditions (fog, smog, rain) and in the presence of obstacles that make it difficult to detect targets (branches, tall grass, thick bushes, etc.).

In digital mode, the device allows for observation both during the day and at night. In night conditions, it is recommended to use a focusable infrared illuminator.

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 Media section of the main menu.
• When the Power saving mode  is activated, video recording continues to run in the background.

The binoculars are equipped with a built-in rangefinder, allowing you to measure distance to objects up to 1500 m away.

How the rangefinder works

1. Turn on the device, set up image according to section Getting Started.

2. Briefly press the LRF button to measure the distance. The rangefinder reticle will appear in the centre of the image. In the bottom of the display you will see distance in meters (or yards – depending on settings).

3. Point the rangefinding reticle at an object and press the LRF button.

Note: if the rangefinder is idle longer than for 4 seconds, it turns off automatically.

Operation in SCAN mode

1. To measure distance in scanning mode, hold down the LRF button for longer than two seconds. Measurement readings will be changing in real time as you point the binoculars at different objects. The text in the LRF widget will become green.

2. If measurement fails, dashes will appear on the display.

3. To turn off the rangefinder, press LRF button again.

4. In 4 seconds of inactivity (no measurement is taken) the rangefinder turns off, the rangefinding reticle with readings disappears from the display.

Notes:

• The rangefinding reticle can be changed in the Observation & Zoom Controls  -> Laser rangefinder  ->  Reticle Type .

• Units of measurement (meters or yards) can be changed in see the System Settings  -> Units of measurement  section.

Additional Information:

• Accuracy of measurement and maximum range depend on the reflection ratio of the target surface, the angle at which the emitting beam falls on the target surface and environmental conditions. Reflectivity is also affected by surface texture, color, size and shape of the target. A shiny or brightly colored surface is normally more reflective than a dark surface.
• Measuring range to a small sized target is more difficult than to a large sized target.
• Accuracy of measurement can also be affected by light conditions, fog, haze, rain, snow etc. Ranging performance can degrade in bright conditions or when ranging towards the sun.

1. Install the Stream Vision Ballistics app from Google Play or AppStore.

2. Go to Profiles tab.

3. Create a profile for your riflescope, ammunition and zeroing distance. Make sure that “Ballistic parameters” switch is on. If your ammo is not on the list, you can enter its parameters manually. The more parameters you specify, the more accurate the recommended point of aiming will be.

If you select a riflescope model, you will be able to display the correction values in clicks.

4. Adjust the temperature, pressure and humidity of the environment while zeroing your riflescope.

5. Enter a profile name and click save.

6. Connect your device to your smartphone using Bluetooth.

7. Load the profile into the device.

To do this, go to the “Devices” tab –> Select your device –> “All device profiles” -> click  on the profile you want to replace and select the created profile from the list.

8. Set the status to “Active” for the ballistic profile. To do this, click on the button next to the desired profile, or select it in the profile selection menu in the device.

9. Make sure that the Activation  option is enabled in the device’s External Ballistics menu.

10. Check the accuracy of your profile settings with a test shot at the shooting range.

Note: profiles for different types of ammunition must be zeroed separately.

11. To activate the use of weather data in your geolocation during the shot, go to the “Devices” tab -> Select your device -> “Outdoor”.

In the External Ballistics section of the main menu, you can configure the following settings of the ballistic calculator:

• Turn on/off the ballistic calculator
• Select a ballistic profile
• Choose correction units

12. Now when you measure distance with the rangefinder, a ballistic calculator widget will appear on the display with correction values in the selected units.

This function is most useful when used with optical scopes. You can set the corrections by rotating the (windage/elevation) turrets for aiming.

Also, if your riflescope uses a Mil Dot reticle, you can shift it during aiming by the values of these corrections.

Pulsar riflescopes (Thermion 2 Pro/Duo/XG, Thermion 2 LRF, Talion, Digex C50) already have a built-in manual ballistic calculator. Therefore, there will be enough to measure the distance with Symbion LRF and set it in the quick menu of the riflescope for the ballistic profile, having previously loaded it into the riflescope via SV Ballistics application.
