Garmin Approach G10 Review: How Accurate Is It?

If you’re looking to purchase a GPS, you’re going to want to consider cost, accuracy and just exactly how essential an item it actually is.  Today we take a look at the Garmin G10, a clear and concise review for you, to help you understand the device and also the pros (and cons) of having a GPS.

Things To Consider Before Buying a GPS

Distance Measurements

When you are shopping for a new GPS, the first factor to consider is the distance measurement capability. Most GPS devices will provide measurements to the front, middle, and back of the green.

While it is more accurate than using the course’s distance markers, it does not offer precise measurement from your ball to the pin. If you are looking for this level of detail, I suggest looking at a laser rangefinder.

Course Compatability

If you are confident that a GPS is a way to go, the next step is to check if it is compatible with your home course. The number of golf courses varies depending on the manufacturer and the device. For example, a product like the Garmin Approach G10 functions on over 40,000 links around the world.

Shot Measurement

To enhance your GPS experience. Some products offer a feature enabling you to measure the distance of your shot. It is a handy feature to help you analyze your performance post-round and improve your distance control over time.

Green View

Of course, GPS devices do not offer the level of accuracy provided by rangefinders. But, the Green View function helps you to obtain as accurate a measurement as you can. Green views enable you to manually position the pin on your device to receive a more accurate reading.

Hazard and Dogleg Measurements

The most basic of GPS devices only provide measurements to the front, middle, and back of the green. However, I recommend that you acquire a GPS with the functionality to measure the distances to hazards and doglegs.

Scorecard Functionality

While it is not essential to the functionality of a GPS, it is handy when they come with a scorecard installed. There is no need to worry about a pencil or a scorecard anymore. It is hassle-free with your GPS device.

Battery Life

The final factor to think about before buying a golf GPS device is the battery life. Bearing in mind that the average round of 18 holes takes you just over 4 hours, you need to ensure it survives the round.

Features & Benefits

Golf Course Functionality

Golf GPS devices require preloaded course data to function and provide you with distance measurements during your round. Although I recommend checking to see if it works on your home course, it shouldn’t be a problem with the Approach G10.

In a 2019 Golf Monthly article, author Elliot Heath suggested that there are 38,864 golf courses in the world. Based on this number, it means that the 42,000 preloaded courses on the Approach G10 include private tracks that you may have never heard of.

Overall. There are very few courses in the world that won’t be preloaded on Garmin’s Approach G10.

Distance Measurements

The GPS provides yardage to the front, middle, and back of the green providing a clearer picture of what club to hit. However, these distances are not measured to the exact pin location, and players looking for precise details may prefer a laser rangefinder. But, the information provided is ideal for the average golfer.

Furthermore, Approach G10 measures the distances to water hazards, bunkers, and doglegs, helping you plan your hole from tee to green.

Green View

The green view feature on the G10 enables you to manually position the pin on the screen to obtain a more accurate measurement of the flagstick. However, there are limited points that you can set it to. But, it allows you to make a better-informed decision regarding club selection.

Shot Measurement

Not only does the Garmin Approach G10 provide yardage to the green and hazards. It also measures the distance of your shot. After hitting your shot select the feature and make your way to your ball. When you reach your ball, stop the function, and you will see the distance of your shot.

Besides boasting to your friends about your abilities with a driver in hand, this feature helps you improve your distance control and accuracy by having a clearer understanding of how far you hit each club.


Besides the measuring capabilities of this device, it also has a scorecard feature that allows you to record your scores digitally. Leave the pencil in your bag and the club’s scorecard in the pro shop. The feature enables you to keep track of both your Strokeplay and Stableford scores for your round.

Stat Tracking

If the distance measurements and the scoring feature weren’t enough for you. The Approach G10 comes loaded with a stat tracking feature that allows you to monitor your GIR, FIR, and Putts per round.

The feature helps you to identify the strengths and weaknesses of your overall game. So you know what to focus on the next time you hit the driving range.

Tournament Legal

Some distance measurement devices are prohibited in tournament play as a result of the detailed readings provided. These devices include laser rangefinders that factor in the slope angle and the elements.

Fortunately, the Approach G10 falls on the right side of the rules, as it is perfectly legal to use in tournaments.
