Features

The Garmin S40 golf watch is a mid-range model that sits between the S60 and S20. It misses some of the S60’s capabilities but is far more complex than the S20. For those who have never used a GPS in golf before, you may be unsure what it does.

A GPS will show you the route from above and aid you in dialing in and controlling your distances. You will be able to see the distances between key locations on the course, which will aid with club selection.

Hopefully, by selecting the proper club, you will be able to lower your scores. One important difference between the S20 and S40 is that the S40 incorporates non-golf-specific tracking features.

It has a range of timekeeping functions such as a stopwatch and alarm, as well as certain health-related features including sleep and hydration levels.

Additionally, it features a selection of running and cycling accessories. These features make the watch more versatile for use of the course, which may be a selling point for those who want a more all-around product over one that does a specific thing.


But not we have to focus on the golf side. The first benefit of this device is that it has over 42,000 courses from all around the world.

Garmin has the most comprehensive variety of courses, including practically all of the main courses in well-populated areas. If you are a bit worried about buying this product without knowing if your local course is on the device, then you can easily check this on the Garmin website.

Garmin is constantly adding new courses to their lineup, so even if yours is not currently on there, there is a high chance that it will be eventually. On this device, you will see the distances to the front, centre, and back of the green. If you are someone who struggles with direction, then this will help you to not end up onthe wrong side of the green. Additionally, it will display the distance between doglegs and layup locations.

If you miss the proper distance into a dogleg, you will almost certainly have a tough or blind shot into the green. This is not great for your scores, so the device helping you to avoid this is very useful. It will tell your location relative to the 100 and 150-yard marks. These are two important distances to know when playing golf. One of the most critical qualities is that it will display the ball’s distance travelled.

Knowing the distance travelled by each club is crucial if you wish to enhance your consistency. This is one of the few ways to access the data.

What the S20 does not include is the capability to compute distances to custom targets. The model up, the S40, enables you to select any location on the course and stores the distance for future reference.

Unfortunately, this must be done manually, and the distance to any point cannot be determined (unlike with the S60).Another complex feature is statistic tracking. Following your round, you will be able to evaluate your performance and discover areas for improvement.

It will track the number of putts made every round, the proportion of greens in regulation, and the percentage of fairways hit. The Autoshot feature maintains track of your club distances, providing you with an average of the lengths travelled by each of your clubs.

This will aid you in deciding which club to attack from a variety of different distances. Also, you may inspect the green shape and operate the pin to get a desired distance. This is another improvement on the S20, where this is not possible. At times, the pin may not be in the centre of the green, in which case this feature is useful.

Finally, the S40 has a digital scorecard, maintains track of your handicap, and can be used in connection with the Garmin CT10 to measure club stats automatically.

Design

What everyone wants in a watch’s design is its comfort and ease of use. Both are crucial, even more so if you are not a watch wearer and so will notice more if a heavy device is on your wrist. Despite the fact that the watch is filled with features, the S40 is significantly more comfortable to wear than the vast majority of its competitors. It is somewhat larger than the S20 but substantially better. There is a distinct difference in comfort between the less expensive watches and the S40, which is good given the range of materials available.

It comes with removable straps that allow you to experiment with different colors and materials. This is an option that the majority of golf watches do not provide.

It is designed similarly to the Forerunner 645 and boasts a 1.2-inch color touchscreen display.

The screen appears to be quite durable and should not be as easily scratched or broken as the screens on some other smartphones.

That said, the watch’s user interface was first a little hard to get used to, which you may notice even more if you have never used a smartwatch before. But once you get the hang of it it should be smooth sailing from there. There are several features, and it may take some time to grasp them all. Something like the S20 has a limited number of features, making it relatively simple to operate, but you should pick it up after an hour or two of playing with it.

Performance

When it comes to performance, people are most concerned with the battery’s life and the watch’s accuracy on greens and hazards. These are the major factor to consider while shopping for a golf GPS.

Battery life usually is slightly under three complete rounds, or just 3 rounds if you play quickly. You can be sure that it will last at least two rounds though, which is the standard for many golf watches.

Your location was quite precise in relation to the greens and hazards (as is the case with the majority of Garmin GPS systems), and it always appeared to be within 4-5 yards of the course markers. This is a very common occurrence with all Garmin watches.

  • No heart rate monitor – it is odd that a watch that contains so many health and fitness features does not have a heart rate monitor built-in
  • Quite expensive – this watch is not cheap, though with so many features built into it that is to be expected

Is The Garmin S40 Worth It?

In summary, if you are in the market for a new golf watch and plan to use it regularly, then we definitely suggest the Garmin S40. It is a very good “mid-range” golf watch and the one a lot of both casual and pro golfers go for.

Garmin Approach S40 GPS Golf Watch

This watch loses a few of the capabilities featured in the Garmin S60 but costs around $130 less.

In comparison to the Garmin S20, the investment is certainly worthwhile if you want to use it regularly. In any event, all three of these watches are excellent golf watches, and you could go wrong with any of them.

Garmin Approach S40 GPS Golf Watch – FAQ’s

What Is The Difference Between The Garmin S10 And The S40?

The Garmin S40 is a huge step up from the S10 model, which looks practically useless in comparison.

The S40 has improved on everything from the S10. The S10 does not have a touchscreen, the screen is smaller and has less resolution, and also does not have quick release bands.

What Is The Difference Between The Garmin S40 And S60?

The Garmin S60 packs load more features into the small watch, though it does not have quick-release bands like the S40. The S60 though has many more golf features including touch targeting, pinpointer, and playslike. 

It is also able to control the music on your phone so you can listen to your favorite playlist while you are out on the course.

Does The Garmin S40 Monitor Heart Rate?

For a device that is able to monitor many health and fitness levels in your body, including your hydration levels and quality of sleep, it is not able to monitor your heart rate.

While this may seem a bit odd, if you are not using this device primarily as a health and fitness tracker, you may not even notice that it is not there.

Is The Garmin S40 Waterproof?

Yes the Garmin S40 is waterproof. Garmin themselves say that the watch is rated at 5 ATMs, which means that it is waterproof to a depth of up to 50 meters.

This makes this watch very durable to use on the course as you won’t have to worry about protecting it in the rain, and if you drop it in a puddle then it will still work perfectly. This also makes the S40 a suitable watch to wear swimming to keep track of your health and fitness levels.
