Buying Guide
- Slope vs. non-slope: Decide whether you need slope compensation for practice rounds or if you require a tournament-legal device with slope off.
- Range and magnification: Longer ranges and higher magnification improve reading accuracy on distant pins but may reduce usability in quick, windy shots.
- Locking features: Pin or flag-lock technologies enhance target stability; consider vibration feedback for confidence on fast greens.
- Power and charging: USB-C or quick-charging options reduce downtime between rounds, especially for frequent players.
- Durability and accessories: Look for water resistance, magnetic mounts, and easy-to-read displays in various lighting conditions.
- Legal considerations: If you compete in tournaments, ensure the device offers a switch to disable slope or verify the device is compliant with local rules.
- Display readability: Transflective LCDs perform better in bright sun; ensure legibility for quick decisions on the course.
