Laser vs GPS Rangefinder: Which Should You Buy?

Laser or GPS: The Short Answer

Both give you accurate yardages, but they work differently. A laser rangefinder measures the exact distance to whatever you point it at, usually the flag, so it is the precision tool. A GPS device or watch uses preloaded course maps to show distances to the front, middle, and back of the green at a glance, so it is the fast, hands-free option. Choose a laser for pinpoint accuracy, a GPS for speed and simplicity, and pick based on how you actually play.

Below we compare the two on accuracy, speed, cost, and convenience so you can buy with confidence. When you are ready, our golf accessories range includes rangefinders and GPS devices chosen by our pros.

How Does a Laser Rangefinder Work?

You look through the device, aim at the flag, and press a button. It fires a laser, measures how long the light takes to bounce back, and displays the exact distance, usually accurate to within a yard. Most modern units have a flag-lock feature that vibrates when it has locked onto the pin rather than the trees behind it.

• Strengths: pinpoint accuracy to the flag, distances to hazards, trees, and layup points, and no reliance on preloaded maps.
• Trade-offs: you have to hold it steady and point it, which takes a moment, and a shaky hand or poor light can make locking on trickier.
• Best for: golfers who want the most precise number for every shot and do not mind taking a second to aim.

How Does a Golf GPS Work?

A GPS device, whether a watch, a handheld unit, or a phone app, uses satellite positioning and preloaded course maps to tell you how far you are from key points, typically the front, middle, and back of the green. You glance at it and go. There is nothing to aim and nothing to lock onto.

• Strengths: instant, hands-free distances, no pointing required, and extra course information like hazard carries and hole layouts on better models.
• Trade-offs: it gives you green distances, not the exact flag position, so you are working to the middle unless the model shows pin position. Courses must be mapped, though the major providers cover almost every UK course.
• Best for: golfers who want speed, simplicity, and to keep the round moving.

Which Is More Accurate?

For the exact distance to the flag, a laser wins every time, because it measures the real pin, wherever it is cut that day. A GPS gives you the middle of the green, which can be several yards different from the flag on a deep green or a tucked pin. If you are a precise iron player chasing tight numbers, that difference matters.

That said, GPS accuracy to the green itself is excellent, usually within a couple of yards, and for most club golfers knowing you have 150 to the middle is plenty to pick a club. The accuracy question really comes down to whether you need the flag or the green.

Which Is Faster to Use?

GPS is quicker in the moment. A glance at your wrist gives you a number with no fuss, which helps pace of play and suits golfers who find aiming a laser fiddly. A laser takes a few seconds to raise, steady, and lock on, though experienced users do it quickly. If speed and ease are your priority, especially in a fourball trying to keep up, GPS has the edge.

What About Cost and Batteries?

Both categories offer strong options from around £80, with plenty of capable lasers and GPS units between £100 and £130. As a rough guide:

• Lasers: run on a single battery that lasts a long time, so there is little to think about beyond an occasional replacement.
• GPS watches and handhelds: need charging, typically lasting one to three rounds per charge, so you have to remember to plug them in.
• Ongoing costs: most reputable GPS providers include free course updates. Avoid any that charge an annual subscription unless you genuinely need the premium features.

Can You Use Both?

Plenty of better players do. A GPS watch gives them a quick number as they walk to the ball, then a laser confirms the exact flag distance before they commit to a club. It is the belt-and-braces approach, and it works. For most golfers, though, one device is enough, and carrying two is more than the game requires.

A Note on Competition Rules

Distance-measuring devices are allowed in most club competitions, but slope-adjusted readings, which factor in uphill and downhill, are not permitted under standard rules. If you play competitions, choose a laser with a slope toggle you can switch off, or a GPS that shows raw distances, so you stay compliant. Always check your club's local rules before teeing off.

The Fayrway Take

If you want the exact flag distance and enjoy dialling in every shot, buy a laser. If you want quick, hands-free numbers and a faster round, buy a GPS. Neither is wrong, and both will help you pick the right club far more often than guessing off a sprinkler head. Our pros use both depending on the day, so browse our accessories range and choose the one that fits how you like to play.
