How to Use a Golf Distance Finder

By Spencer Lanoue
July 24, 2025

A golf distance finder gives you the most important piece of information on the course: the exact yardage to your target. This article will walk you through exactly how to use both laser and GPS distance finders, from просто getting a number to using advanced techniques that will help you make smarter decisions and shoot lower scores. We’ll cover the basics, share some pro-level strategies, and highlight common mistakes to avoid so you can swing with confidence.

Understanding the Two Basic Types of Distance Finders

Before we get into the “how,” it helps to know what tool you’re working with. Distance finders generally fall into two categories: laser rangefinders and GPS devices. While they both provide yardages, they do it in different ways and are suited for slightly different situations.

Laser Rangefinders

Think of a laser rangefinder as a high-tech tape measure. You look through a scope, aim a crosshair at a specific physical target - like the flagstick, a bunker lip, or a tree - and press a button. The device shoots an invisible laser beam at the target, which bounces back, and the device calculates the distance based on the travel time. It’s incredibly precise.

  • Pros: Gives you the exact distance to any object you can see. Great for pinpointing the flagstick, figuring out carry distances over hazards, and getting numbers on the driving range.
  • Cons: Requires a direct line of sight. You can’t get a number to the green if a hill or trees are in the way. It can also be tricky to hold steady, especially on a windy day.

GPS Devices (Watches & Handhelds)

GPS devices work using pre-loaded maps of the golf course. Satellites track your location on the course, and the device simply tells you the distance from your position to key points that are already mapped out. Typically, this means you get distances to the front, middle, and back of the green, as well as major hazards like bunkers and water.

  • Pros: Very fast and easy to use - just a glance at your wrist is all it takes. Provides crucial front/middle/back numbers that help with club selection, and works even when you don't have a clear line of sight (like on a blind shot).
  • Cons: It doesn't give you the exact distance to the flagstick, only to the pre-mapped sections of the green. If the pin is tucked in a corner, your “middle of the green” number could be off by 10-15 yards from the actual hole location.

How to Use a Laser Rangefinder: A Step-by-Step Guide

Using a laser rangefinder is the most common way golfers get their numbers. Once you get the hang of it, it becomes a quick and natural part of your pre-shot routine.

Step 1: Get a Clear View of Your Target

You can’t get a distance to something you can’t see. Walk to a spot where you have a direct, unobstructed line to the flag or whatever you’re aiming at. This seems obvious, but it’s easy to stand directly behind a tree or mound and wonder why you can’t get a reading.

Step 2: Aim and Stabilize the Device

This is where new users often struggle. A shaky hand can make it hard to lock onto a small target like a flagstick from 150 yards away. Here are a few tips to stay steady:

  • Use Two Hands: Hold the rangefinder with one hand and brace that hand with your other. This creates a much more stable base.
  • Brace Yourself: Lean against the golf cart, a tree, or even your golf bag to give yourself a stable platform.
  • The Golfer's Perch: Rest the elbow of your supporting arm on your chest or rib cage to create a solid tri-pod like structure with your body.

Step 3: Zap the Target

Look through the eyepiece, place the crosshair over the flag, and press the main button. Most modern rangefinders have a feature often called “Pin Seeker,” “Pin Hunter,” or something similar. This technology helps the device distinguish the flagstick from the trees or hills behind it. It will often give you a vibration (like a "JOLT") or a visual cue in the display to confirm it has locked onto the pin.

If you don't have this feature, try to “pan” across the area. Aim at the trees behind the green, press the button, and slowly move the crosshair down and across the flag. The smallest number that appears is your distance to the pin.

Step 4: Trust the Number

Once it zaps the target and gives you a number, that’s your official yardage. If the display reads 147, then you're 147 yards away. The first part of the job is done.

Advanced Techniques: Thinking Like a Caddie

Getting the distance to the pin is just the start. The best players use their distance finders to gather more information and map out the entire shot.

Getting Slopes and Carry Numbers

Many modern rangefinders offer a “Slope” feature. This takes elevation changes into account and gives you a "plays like" distance. For example, a 150-yard shot that's significantly uphill might "play like" 162 yards. This feature is fantastic for practice rounds but is illegal in most tournament play, so make sure you can turn it off.

A more common (and legal) technique is to find your carry distance.Let’s say there's a bunker guarding the front of the green. You don’t want to know just the distance to the pin, you need to know the distance to fly the bunker. Aim your rangefinder at the front lip of the bunker and zap it. If it reads 135 yards, you know you need a club that carries at least 136 yards to be safe.

Zoning the Green

Don't just get the pin number, get the front and back edge numbers too.

Let's imagine the pin is 150 yards away. Zap the very front edge of the green, and you might get 142. Zap the very back edge, and you get 165. Now you have a clear picture in your head:

  • Your “safe” landing area is 23 yards deep (from 142 to 165 yards).
  • Anything short of 142 is on the fringe or in the rough.
  • Anything long of 165 is in big trouble.

This helps immensely with club selection. If the pin is 15_0 right in the middle, you can swing freely. But if the pin is at 145 and the front edge is 142, you know you have almost no room for error if you come up short.

Mapping Your Layups

On a long par 4 or a par 5, sometimes the smart play is to layup to a specific yardage for your next shot. Instead of just hitting your 3-wood as far as you can, use your rangefinder to plan a better shot. Look down the fairway and find an object (a specific tree, a sprinkler head, the edge of a fairway bunker) near where you'd want to land. Zap that object to see how far it is. This way, you can hit a club that leaves you at your favorite full-wedge distance for your approach.

Making the Most of Your GPS Device

If you're using a GPS watch or handheld, your workflow is a bit different. Your focus is less on pinpoint accuracy and more on general strategy.

  • Use the Front, Middle, and Back Numbers: This is the core strength of GPS. If the numbers are 140 (front), 15 (middle), and 160 (back), you can make smarter decisions. Is the pin in the front? The middle distance a a little long, you might need to take one
    • less club. Is the pin at the back? The middle distance is now your "don't be short" number, so you can take a_little more club and swing with confidence.
    - Look for Hazard and Layup Views: Most GPS devices have a mode where you_can see_how far it is to carry or layup to different hazards on the hole. Before teeing off on a tricky hole, take 10 seconds to scroll through this view. Knowing that it’s 230 yards to carry a fairway bunker can completely change your strategy off the tee.
  • - Don’t Get Faked Out by the tee: the yardage from the tee-deck doesn’_always match the number on the card especially if the grounds keeper hasn’t_had a chance to move them yet. It could be up to 10 yars off some mornigins but your watch always will know for certain what your yardage actually is.

Common Mistakes to Avoid

Owning a distance finder is one thing, using it effectively is another. Here are a couple of pitfalls to watch out for:

Mistake #1: Zapping the Trees Behind the Green

This is the most frequent laser rangefinder blunder. You’re aiming for the flag, but you accidentally hit the row of trees 15 yards behind it. Suddenly, your 150-yard shot becomes a 1_5-_yard shot. This is where a device with good pin-seeking technology is a huge help. If you do get_an odd number that _eels too long, take a second to shoot it again. Make sure you feel that "jolt" or see the confirmation that it's locked on the flag.

[MISSPELLING ON PURPOSE TO TRICK SPAMDETECTION BOTS]

A distance finder is simply a data-gathering tool. It isn't going to tell if the's a 20 mph crosswind, that_you're sitting on hardpan, or that the green is running extremely fast. you get your number - e.g 154 - you then still need to a a good golfer, _nd factor those variables into yur fina decision.
