Golf GPS watch vs rangefinder: which is better?
A laser rangefinder gives the exact distance to the flagstick or any target you can see; a GPS watch gives instant front, middle and back-of-green and hazard distances without aiming, including on blind shots. Choose a rangefinder for precise approaches, a GPS watch for convenience, or a hybrid for both.

Head-to-head
| GPS watch | Laser rangefinder | |
|---|---|---|
| Distance to pin | Green front/middle/back | Exact, to whatever you aim at |
| Blind shots | Yes | Needs line of sight |
| Hazard and layup distances | Yes, from course maps | Only if you can aim at them |
| Speed | Glance at your wrist | Pull out, aim, read |
| Extras | Stats, shot tracking, fitness | Slope, pin lock, vibration |
| Coverage | Depends on preloaded maps | Works anywhere |
Are they legal in competition?
Under the Rules of Golf, getting distance information from a device is allowed, but a Committee may prohibit distance-measuring devices by Local Rule (Model Local Rule G-5). Measuring elevation changes is not allowed during a round, which is why many rangefinders let you switch slope off (Rule 4.3).

Frequently asked questions
Is a GPS watch as accurate as a rangefinder?
For green front/middle/back distances, GPS is usually close enough; a laser is more precise to the exact flagstick.
Can you use a rangefinder with slope in tournaments?
Only with the slope function turned off and if the competition permits distance-measuring devices.
Do golf GPS watches need a subscription?
Many include preloaded course maps without a subscription; check the specific model.
