Laser rangefinder, GPS watch or voice GPS: which should you choose?
They all measure distances, but not in the same way. A laser rangefinder targets a precise point; a GPS calculates your position against a map of the course. The right choice depends on what you expect: the exact distance to the flag, an overview of the green, or simply a quick number without interrupting your game.
The laser rangefinder: accuracy to the pin
The rangefinder sends a laser beam to the target and measures how long it takes to come back. The result: the exact distance to whatever you aim at, whether that's the flag, the edge of a bunker or a tree at the end of the fairway.
- Strengths: precise distance to the day's pin position, wherever it is; can measure any visible landmark; no reliance on a course database.
- Limits: you need to see the target (tricky on a blind green or behind a mound); you have to aim, which takes a gesture and a few seconds.
- Who it's for: golfers who attack flags and want an exact number on every approach.

The GPS watch: the map on your wrist
The watch calculates your position and shows the distances to the front, centre and back of the green, often with hazards.
- Strengths: always on your wrist; distances to blind greens; often extra features (scoring, statistics, activity tracking).
- Limits: the distance is to the green, not to the exact pin position; you have to look down and navigate screens; the battery needs regular charging.
- Who it's for: golfers who like an overview and keep track of their stats.
The voice GPS: distance without looking
A voice GPS works like a GPS watch, but without a screen: press a button and the device announces the distance out loud.
- Strengths: no screen to read, no aiming; very light; automatic course and hole recognition; announcements in your choice of English, French, Spanish or German; very affordable.
- Limits: like any GPS, it gives the distance to the green (front, centre, back) rather than to the exact pin.
- Who it's for: golfers who want to play quickly and simply, without any "tech" to fiddle with.

The comparison at a glance
| Criterion | Laser rangefinder | GPS watch | Voice GPS |
|---|---|---|---|
| Distance to the exact pin | Yes | No (green) | No (green) |
| Front / centre / back of green | Measure one by one | Yes | Yes |
| Blind green | Difficult | Yes | Yes |
| Action required | Aim | Look at the screen | Press a button |
| Relies on a course database | No | Yes | Yes |
Why not combine the two?
Many golfers use a GPS for the overview and a laser for the exact distance to the flag. The voice GPS + rangefinder combination is particularly effective: the VC4 instantly announces the distance to the green on every shot, and the rangefinder takes over on approaches where the pin position makes the difference.
How to decide
- You want maximum accuracy and you attack flags: laser rangefinder.
- You want simplicity, to play quickly, on a smaller budget: voice GPS.
- You often play courses you don't know: GPS (voice or watch) helps on blind holes, the laser adds the flag.

Frequently asked questions
Is a GPS less accurate than a rangefinder?
They don't measure the same thing. The laser measures the exact distance to the target you aim at; the GPS calculates the distance between your position and mapped points on the green. The GPS doesn't know where the pin is on the day.
Are both allowed in competition?
Yes, as long as the event allows distance-measuring devices and prohibited functions (notably slope compensation) are switched off.
