2. To exit SCAN mode, press LRF (6) button again.

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

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

Notes:

• To select a rangefinding reticle, please see the Reticle Type subsection in the Rangefinder section.
• To select a unit of measurement (meters or yards) go to the Units of Measure subsection of the General Settings 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. First, make sure that your device has the latest firmware version 3.0 or higher installed.

7. Load the profile into the device.

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

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

In the 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

13. 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 Merger 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.

The presence of such pixels is associated with the manufacturing technology of displays and microbolometer. It is not a defect.

Possible cause
In warm climates, objects in the background of a thermal image heat up differently because of thermal conductivity, generating a high temperature contrast and a sharper thermal image.
In cold climates, objects in the background of a thermal image will cool down to roughly the same temperature, which leads to a greatly reduced temperature contrast and a degraded image quality. This is normal for all thermal imaging devices.

Possible cause
There is an object in front of the receiver or emitter lens preventing signal transmission.
Solution
Make sure that: the lenses are not blocked by your hand or fingers; the lenses are clean.

Possible cause
The device is not being held steadily when measuring.
Solution
Keep the device steady when measuring.

Possible cause
Distance to the object exceeds 1000 m.
Solution
Pick an object at a distance not longer than 1000m.

Possible cause
Low reflection ratio (for example, tree leaves).
Solution
Pick an object with higher reflection ratio (see point Additional Information in section Laser Rangefinder.

Possible cause
Inclement weather conditions (rain, mist, snow).
