Laser Rangefinder

The riflescope is equipped with a built-in rangefinder (14), allowing you to measure distance to objects up to 800 m away.

How the rangefinder works:

1. Turn on the riflescope, adjust image according to section Powering on and Image Setting.

2. Briefly press the LRF (3) button to measure the distance. The rangefinder reticle will appear in the centre of the image.

3. If PiP mode is on, the PiP window remains active.

4. If PiP mode is off, the activation of the rangefinder automatically turns on the PiP window with the last digital magnification set for it and a reticle in it.

5. Point the rangefinding reticle at an object and press LRF (3) button. In the top right corner of the display you will see distance in meters (or yards - depending on settings).


  • If the rangefinder is idle longer than three seconds, it turns off automatically.
  • The point of aiming of the rangefinding reticle and the aiming reticle in the PiP window might not coincide due to aiming reticle shift after zeroing.
  • To see the recommended aiming point while measuring the distance, activate the Ballistic Calculator.

Operation in SCAN mode:

1. Turn on the rangefinder by briefly pressing the LRF (3) button.

2. Hold down LRF (3) button for longer than two seconds. Measurement readings will be changing in real time as you point the riflescope at different objects. In the top right corner a message SCAN appears.

3. In case of unsuccessful measurement dashes will appear on the display. 

4. To turn off the rangefinder hold the LRF (3) button.


  • To select a rangefinding reticle, please go to submenu Rangefinder in the main menu.
  • To select units of measurement (meters or yards) go to submenu General Settings in the main menu.

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.
  • 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.
  • Measuring range to a small sized target is more difficult than to a large sized target.
