Stadiametric Rangefinder

Thermal imaging riflescopes are equipped with a stadiametric rangefinder, which allows you to determine the approximate distance to an object, if its size is known.

  1. To select the Stadiametric Rangefinder function, enter the Quick Menu by briefly pressing the controller button (6).
  2. Press the controller button (6) briefly to select the icon .
  3. The display will show the lines for measurements, the icons and numbers of the measured distance for three objects.
  4. Place the bottom fixed line under the object.
  5. Rotate the controller ring (6) to move the upper line relative to the lower horizontal fixed line so that the object is located directly between the lines. A target range automatically recalculated along with movement.
  6. To exit the rangefinder mode, briefly press the controller button (6) or wait 10 seconds to exit automatically.


  • There are three predefined values for objects: Hare – 0.3 m high, Boar – 0.7 m high, Deer – 1.7 m high.
  • The measured range value is rounded off before being displayed – for large range values up to 5 m, for shorter range – up to 1 m. 
  • To select a unit of measurement (meters or yards), go to the General Settings  menu item => Units of Measure submenu.
