Kahles Helia 42 RF 10x42

The lightweight and ergonomic HELIA 42 RF perfectly combines brilliant optics with reliable targeting up to 1,200 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.

EAC Function:

• 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

Features

• Easy and reliable targeting up to 1,200 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 3,600 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
