Kahles Helia RF 10x42 Binoculars

The KAHLES HELIA 42 RF rangefinder binoculars combine premium hunting optics with a built-in laser rangefinder, giving hunters and shooters accurate distance measurement up to 1,500 metres on real-world targets like deer and trees. Lightweight and ergonomic, this rangefinder binocular is designed for one-handed use in the field, making it a strong choice for stalking, mountain hunting, and long-range shooting preparation.

This updated HELIA RF model increases maximum measuring distance by 50% over its predecessor through improved distance measurement technology. High-clarity lens technology delivers bright, sharp images with natural contrast in low light and challenging conditions, a key feature for dawn and dusk hunting.

Key rangefinder features include:

• Patented EAC (Enhanced Angle Compensation) technology for accurate angle-corrected distance readings on steep terrain, more precise than the standard Rifleman's Rule because it accounts for ballistics, not just slant range
• Long-Range (LR) mode for ranging easy-to-detect targets out to 4,500 metres
• Scan mode for continuous measurement of moving targets
• High-resolution OLED display with five manually adjustable brightness levels, switchable between metres and yards
• On-screen temperature and air pressure readouts
• Extended battery life rated for approximately 4,000 measurements

Built with a waterproof, protective-coated aluminium housing, the HELIA 42 RF is designed to perform in wet, cold, or dusty hunting conditions while staying comfortable and non-slip in hand. The ergonomic button layout allows hunters to view and range targets simultaneously, without breaking focus on the animal.

Perfect for: deer hunting, mountain and alpine hunting, long-range rifle shooting, bowhunting range estimation, and hunters who want rangefinding and optics in a single lightweight unit.
