Buying Guide for Golf Rangefinders
Choosing the right golf rangefinder depends on several key factors to ensure it meets your playing style and course needs.
Range and Accuracy
Select a rangefinder with a maximum distance range suitable for your course type. Standard ranges vary from 800 to 1500 yards. Accuracy usually ranges between ±0.5 to ±1 yard; more precise devices improve shot confidence.

Additional Features
- Continuous Scan Mode: Useful for quickly measuring multiple targets.
- Multi-functionality: Some devices double as hunting rangefinders with speed measurements and horizontal/vertical distance modes.
