Laser Rangefinder

The binoculars are equipped with a built-in rangefinder (1), allowing you to measure distance to objects up to 1000m away.

Single Measurement Mode

1. Turn on the device, set up image according to section Powering on and Image Setting.

2. Briefly press the LRF (6) button to measure the distance. The rangefinder reticle will appear in the centre of the image. In the top right corner of the display you will see distance in meters (or yards - depending on settings).

3. If PiP mode is activated, the PiP window remains active upon activation of the rangefinder.

4. Point the rangefinding reticle at an object and press the LRF (6) button.

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

Scan Mode

1. To measure distance in scanning mode, hold down the LRF (6) button for longer than two seconds. Measurement readings will be changing in real time as you point the binoculars at different objects. A SCAN message will appear in the upper right corner of the image.

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.


  • 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.
