Kahles Helia 42 RF
Available in:
8x42 RF
10x42RF
The lightweight and ergonomic HELIA 42 RF perfectly combines brilliant optics with reliable aiming up to 1,500 m on common hunting targets (deer, tree). It is distinguished by intuitive simple operation and useful hunting functions such as patented EAC (Enhanced Angle Compensation) and scan mode.
Simple and reliable aiming up to 1,500 m on common hunting targets
Intuitive simple menu navigation
Patented EAC (Enhanced Angle Compensation) function for angle correction
LR (long range) function for determining distance of easily detectable targets up to 4,500 m
Top quality OLED display with five manual brightness settings and display in meters or yards
Display of scan mode, temperature and air pressure
Extra long battery life ~ 4,000 measurements
Suppose the distance to the target is 400 m
Assume an angle of 40°
Shooter's rule result: 306 m
Result EAC function: 321 m
As the example shows, the distance determined by the EAC function differs by 15 m from that of the shooter's rule, a distance that, depending on caliber, projectile, barrel length, etc., can already have a significant impact on the accuracy of a shot.
