GPS devices trade a laser rangefinder's pinpoint precision for speed and convenience — instant yardages without aiming at anything. The right one for you depends on a few practical factors more than brand name.
Watch vs. handheld
A GPS watch is glanceable and hands-free, ideal if you want minimal interruption to your pre-shot routine. A handheld gives a larger screen for reviewing full hole layouts and hazard positions in more detail. See our GPS devices equipment guide for the full comparison.
Course database and update policy
Confirm your regular course(s) are actually included before buying, and check whether new course map updates are free or require an ongoing subscription — this varies meaningfully between brands and models.
Battery life under real conditions
GPS mode (actively tracking, not just standby) drains battery faster than standard smartwatch use. Look for devices rated to comfortably cover an 18-hole round with buffer, especially if you play back-to-back rounds or forget to charge overnight.
Green mapping detail
Basic front/center/back yardages are the minimum useful feature. If you want to make more precise layup and approach decisions, look for a device with full green shape and hazard-outline mapping rather than just three numbers.
