Laser rangefinders vs. GPS — getting accurate yardages fast.
A rangefinder removes the single biggest source of wasted time and guesswork in a round: figuring out exactly how far you are from the target. Laser rangefinders and GPS devices solve this differently, and each has a real, distinct advantage.
Laser rangefinders
Laser rangefinders give you the exact distance to whatever you point them at — the flag, a bunker edge, a tree you need to carry — with typical accuracy within a yard. Look for:
- Fast target lock / target acquisition, sometimes called "pin-seeking" or "flag lock" technology, which vibrates or flashes to confirm you've locked the actual pin and not the background.
- Magnification — 6x is standard and sufficient for most golfers; higher magnification helps at longer distances but requires a steadier hand to use effectively.
- Slope adjustment — calculates a slope-adjusted "plays-like" distance accounting for elevation change. Note that slope-adjusted readings are not permitted in tournament play under the Rules of Golf; most rangefinders include a toggle switch to disable slope for legal tournament use.

GPS devices (watches and handhelds)
GPS devices use preloaded course maps to instantly show distances to the front, center and back of the green without needing to aim at anything — faster for general "how far to the green" information, though less precise for pinpointing specific hazards or exact flag position compared to a laser. See our GPS devices guide for more on this category.
Which one should you buy first
If you have to pick one, a laser rangefinder gives more precise, actionable information (exact distance to the actual pin, not just the green) and works on any course without needing to be preloaded — it's the better first purchase for most golfers. A GPS watch is a strong second purchase or first choice if you specifically want glanceable, no-hands yardage without stopping to aim a laser on every shot.
