Golf Rangefinders: GPS Watch or Laser First?A GPS watch gives you the center of the green. That can be one club off from the pin

Updated: Oct 13, 2026Contains affiliate links

Make your first one a laser. My choice is the Nikon COOLSHOT PROIII STABILIZED. The regular price at Nikon Direct is ¥64,900.
Whether your golf rangefinder should be a GPS watch or a laser comes down to the difference in what they measure. A GPS watch gives you the distances to the front, center and back of the green. Not the distance to that day's pin.
The center and the pin can be one club apart.
As a gear nerd who averages 72 with a best of 68 and spends most of his time looking into the numbers behind clubs and gear, I've lined up the 2 methods using official numbers. By the end you'll be able to decide which to buy first, and whether a GPS watch alone is enough.

GPS watch vs laser rangefinder: bottom line

A GPS watch measures the shape of the green; a laser measures the flag itself

I'll put my laser pick next to 1 representative GPS watch. For the watch I chose the Garmin Approach S50. Both sets of numbers are from the official pages.

Sources: Nikon's official product page and key specifications and Nikon Direct's regular price; Garmin Japan's official product page and press release (all checked Oct 13, 2026). Nikon's error figure is the value for under 700 yards.

The most important line in the table is the first.

A GPS watch has maps of golf courses inside it. For the S50, that's more than 43,000 courses worldwide. It finds your position by GPS, calculates the way to the green on the map, and gives you 3 numbers: front, center and back.

The map isn't rewritten every morning. The pin moves every day.
So a GPS watch doesn't know where today's pin is. The S50 has a feature that lets you move the pin on the screen with your finger, but where you move it to is something you decide with your own eyes.

A laser is the opposite. It has no map; it simply hits the flag with light and turns the time it takes to come back into a distance. So as long as you can see the flag, it measures the same way at a course you're visiting for the first time, and wherever the pin is cut.

Look at the error line, too. Nikon states it as a number: ±0.75 yards. Garmin's official page has no figure for GPS error. My reading is not that they're hiding it, but that it changes with the sky conditions and the trees around you, so it's hard to put into a single number.

The gap between the center and the pin comes to one club

Let me work through an example. These aren't from a real hole; they're numbers for the sake of explanation.

Say the GPS watch shows 140 yards to the front, 155 to the center and 170 to the back. That's a green 30 yards deep.
If the pin is cut 5 yards from the front, it's 145 yards to the pin. That's 10 yards different from the 155 to the center.

10 yards. That's one club.
With irons spaced 4° apart in loft, the gap between clubs is about 12 yards (from the common rule of thumb of about 3 yards per 1°; the same assumption as the Club Setup Check).

Trust the center number and take a 7-iron, and by this math you have one club too much for a front pin: you're on the green, but with a 10-yard putt left.
The more you want to lower your score, the more these 10 yards matter. This is why my first one is a laser.

Even with a GPS watch, you can narrow the gap by looking at the front and back numbers and estimating the pin position by eye. But an estimate is an estimate. It doesn't match a number from light hitting the flag.

A laser loses in 3 situations. Nikon has removed 1 of them

Lasers have weaknesses, too. I'll lay them out without hiding any.

It can't measure what it can't see

On an uphill shot you can see only the tip of the flag. The green is on the other side of the trees. On holes like these, a laser can do nothing. A GPS watch gives you the distance from the map even when you can't see the target.

Distances to the front and back of ponds and bunkers are another thing a GPS watch does well. With a laser you can measure them by aiming at something on the edge, but it takes more effort.

It takes effort to aim

Take it out of your pocket, look through it, press the button. With a GPS watch you just look at your wrist. The GPS watch wins this one.

When your hand shakes, it measures what's behind the flag

If you aim at a target 150 yards away and your hand moves 0.5°, the point the light hits shifts about 1.3 yards sideways (my calculation: 150 yards × tan 0.5°). A flag is thin. Light that misses it carries on to the trees behind.

Nikon has removed this weakness inside the body.
The official explanation is that it "reduces the shaking of the view in the viewfinder caused by hand movement and, at the same time, also corrects the shake of the emitted laser beam." In other words, it steadies not just the view you see but also the direction of the light going out.

This part is really well done.
The moment it measures the flag, a mark lights up in the viewfinder and the body vibrates, and the number appears in 0.1 seconds. The time spent wondering "Did I just measure the flag, or a tree?" goes away. ±0.75-yard accuracy only means something once the light hits where you aimed. This is a unit that builds in that precondition on the machine's side.

I'll write about the weak points, too. About 205g is noticeably heavy in a pocket. The battery is a CR2, not rechargeable. If you want something lighter, Bushnell's Pinseeker Pro XM Jolt is 192g and rechargeable (published error within ±1 yard). If you want lighter still, the FineCaddie J2000 is 113g.

Who a GPS watch is enough for, and who should buy one first

I'm not looking down on GPS watches. For the right person, one is more useful than a laser.

• People who are happy to land anywhere on the green.What you need is the distance to the center. A look at your wrist and it's there.
• People who often play courses with many holes where you can't see the flag.
• People who want to decide whether to lay up from the distance to a pond or bunker.
• People whose pre-shot rhythm is thrown off by taking a device out and putting it away.

The S50 is 29g. Light. It runs about 15 hours using GPS, so at 5 hours a round, that works out to 3 rounds without charging (my calculation).

The GPS watch's old weakness, "it doesn't know the pin," has started to change, too. Since Oct 9, Voice Caddie has been running a service that sends the day's pin positions, as set by the golf course, to the watch. At launch, about 504 golf courses are supported and it's free to use (confirmed with the official source on Oct 9). If the courses you play are supported, that changes things. I've put the compatible models and conditions in the Auto Pin article.

If you're choosing a GPS watch, the Garmin Approach S72, with a large screen that even shows swing numbers, is also a candidate. It's 48g in 47mm, with about 20 hours in golf mode.

If you can't decide, count 3 things at your usual course

Before you buy, you can check for ¥0. Think back over the 18 holes of a course you play often.

1. From where you hit your second shot, on how many holes can't you see the flag?If it's 6 or more, a laser is unusable 1 time in 3. The GPS watch comes first.
2. Do you change clubs depending on whether the pin is front or back?If you do, a laser's number feeds straight into your club choice.
3. Borrow a playing partner's rangefinder for just 1 hole.If looking through it to measure doesn't bother you, a laser; if it's a hassle, a GPS watch.

I think No. 3, borrowing, is the quickest. More than specs, measuring once with your own hands tells you a lot.

One thing to say up front. Changing your rangefinder won't improve your ball striking.
Someone whose 7-iron varies from 145 yards to 175 yards doesn't need ±0.75 yards. If your distance for each club isn't settled yet, that comes first. At a range with ball-flight data, write down your distance with each club, 10 balls apiece. The rangefinder can wait until after that.

If you play in competitions, get a model that can turn elevation off

Rule 4.3 of the Rules of Golf allows you to get distance with a rangefinder. What it doesn't allow is measuring elevation changes. If you display a distance adjusted up or down for an uphill or downhill shot, it's a breach.

So for competition, a model has to be able to turn the elevation display off. Bushnell's Pro XM has a slide switch on the left side of the body, so you can see from the outside that it's off. The Garmin S50 lists Tournament Mode in its official spec table.

One more thing. The Committee can ban rangefinders themselves by Local Rule. Read the terms of the competition you're entering first. Choosing a model comes after that.

Buy the second one once the gaps in the first start to bother you

Some people carry both. The laser for the pin, the GPS watch for ponds and the depth of the green. That does fill the gaps.

But together that's over ¥130,000. It's not a matter of getting both from the start; I think it's enough to use the first one for half a year and think again once you can clearly see where it falls short.

In order from the least money. Count the holes at your usual course where you can't see the flag (¥0). Borrow a playing partner's rangefinder (¥0). Buy rangefinder No. 1. If the gaps bother you, add the other type.

Three things to take away.
A GPS watch gives you the front, center and back of the green, not today's pin.
The gap between the center and the pin can be 10 yards = one club.
A laser can't measure what it can't see. If your courses hide the flag, the GPS watch comes first.

If it were me, I'd buy the Nikon first, to aim at pins. ¥64,900. Not cheap. Even so, only a laser lets you choose a club from a number taken by light hitting the flag.

On your next round, try counting the holes where you can't see the flag from your second shot. How many were there?
