Knowing your exact distance changes how you play golf — guessing costs the average golfer several shots a round. The question is which tool: the laser rangefinder or the GPS watch. Both are excellent; they are excellent at different things.
How Each One Works
A laser rangefinder measures the precise distance to whatever you aim it at — the flag, a bunker lip, a tree. A GPS watch (or handheld/phone app) knows the course map and shows distances to the front, middle and back of the green plus mapped hazards, automatically, on your wrist. Lasers answer "how far is that exactly?"; GPS answers "where am I and what is ahead?" without being asked.
The Case for the Laser
Pinpoint accuracy to the actual flag position — not the green’s middle — which matters increasingly as your iron play sharpens. Any target, any course, zero setup: lasers work on day one at a course no database has mapped. Better players and flag-hunters get the most from them. Downsides: you must aim them (shaky hands and rain complicate this), they measure only what you can see — useless for blind shots and doglegs — and decent models start around 150 with premium ones triple that.
The Case for the GPS Watch
Effortless: glance at your wrist, get front-middle-back, swing. Blind shots, doglegs and lay-ups are where GPS shines — it measures what lasers cannot see. Most watches add shot tracking and stats, which quietly becomes the biggest long-term value: data on how far you really hit each club (spoiler: less than you think) improves decisions more than any single yardage. Downsides: green numbers are zones, not the flag; battery management; and course database coverage matters for remote layouts.
Which Suits Which Golfer
Higher handicaps and beginners: GPS watch. Front-middle-back is honestly all you can use yet, the convenience keeps you playing quickly, and the stats accelerate learning.
Single figures and flag hunters: laser. Exact pin numbers feed precise wedge play.
Travelling golfers: laser for unmapped courses, or check the watch’s database covers your destinations.
The committed: both — watch for position and tracking, laser for approach shots. Plenty of serious amateurs carry the pair.
What to Spend
The mid-market is the value zone in both categories. Lasers: reliable slope-switchable models sit around 150 to 250 — premium optics beyond that buy nicer glass, not lower scores. Watches: 150 to 300 covers models with full mapping and tracking. On slope (elevation-adjusted distances): brilliant for practice and casual golf, but not legal for handicap and competition rounds unless disabled — buy a model with a clear on/off switch.
The Bottom Line
If you buy one device: GPS watch for most golfers, laser once your approach play deserves exact numbers. Either way, the biggest gain is free: trust the number, take enough club, and stop coming up short — the amateur game’s most reliable mistake.

Quick Answers
Rangefinder or GPS watch: which should I buy?
Rangefinders give exact yardage to the flag; watches give front-middle-back at a glance. Precision versus convenience.
Are rangefinders legal in competitions?
Distance-only modes are widely allowed; slope usually must be switched off. Check the competition rules.
Which is better for beginners?
A GPS watch: fewer decisions, faster play.
