กล้องวัดระยะ KAHLES HELIA RF 42 OKL-20025
The lightweight and ergonomic HELIA 42 RF perfectly combines brilliant optics with reliable targeting up to 1,500 m on common hunting targets (deer, tree). It stands out for intuitive simple handling and useful hunting features like patented EAC (Enhanced Angle Compensation) and scan mode.
- 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.
