Features

  • Easy and reliable targeting up to 1,500 m on common hunting targets
  • Intuitive simple menu navigation
  • Patented EAC-function (Enhanced Angle Compensation) for angle correction
  • Long-range (LR) function for ranging easy to detect targets up to 4,500 m
  • Premium-quality OLED display with five manual brightness settings and display in meter or yards
  • Scan Mode, temperature and air pressure display
  • Extra long battery lifetime ~ 4,000 measurements

Assume the distance from the target is 400 m
Assume an angle of 40°
Rifleman’s rule result: 306 m
EAC function result: 321 m

As the example shows, the distance determined by the EAC function differs from that of the rifleman’s rule by 15 m, a distance which, depending on calibre, projectile, barrel length, etc. can already have a significant impact on the accuracy of a shot.
