Finding the distance to green can be an arduous and time-consuming process. Even carrying a range finder in your bag can consume quite a few minutes.

In this Garmin Approach S20 review, we will look at how wearable GPS watches address the problem by providing you with a variety of information immediately.

This will help you to play with confidence and speed up play.

Garmin Approach S20 Summary

Everyday Watch Combined With Golf GPS 


The Garmin S20 is a compact, lightweight, and wearable entry-level golf GPS watch that offers a variety of tracking and display features.

Feedback of the data collected is via a small screen that is readable even in bright sunlight.

It displays yardages to the front, middle, and back of the green, the hole number, and a rather archaic looking outline of the green.

Navigation through the menus is button driven and there is no touch screen.

In the box, you will get the Garmin S20 golf GPS watch and a USB linked charger clip. The yardages and the par are displayed clearly on the screen.



Is the S20 for me?

This Garmin Approach S20 GPS watch review will provide information on whether this golf watch will suit you.

If you are a golfer that requires only the basic information for the golf hole in play on a monochrome LCD, it will fit your requirements.

However, if you require a colorful experience with advanced functionality that can be controlled via a touch screen, you will find this watch unfit for your purpose.

Garmin S20 Golf GPS Features & Benefits

After the introduction that explains what the golf watch is, it begs the question “What does the Garmin Approach s20 do?”.

I will expand on the features and benefits you can expect.

AutoShot – Rating 4.4/5

AutoShot must be enabled for automatic shot detection in the System Settings menu.

Your Approach device features automatic shot detection and recording for every shot you play from the fairway.

It records your location so it can be viewed later on the Garmin Connect™ Mobile app and the Garmin Golf™ app.

It does not detect putts in standard form.

You can purchase a CT10 sensor separately and attach it to your wedges and putter to track greenside chip shots and putts as well.

Preloaded courses – Rating 5/5

There are more than 41,000 golf courses from across the globe preloaded onto the Garmin S20 golf watch.

CourseView – Rating 4.8/5

CourseView feature automatically updates frequently played courses. If you are wondering how much does it cost to update your Garmin GPS, it’s free. 

How accurate is the Garmin Approach S20? – Rating 4.4/5

A question frequently asked is whether the S20 GPS watch is accurate for golf. 

In short, most golfers will consider a measurement that provides the distance to within 5 yards or less as accurate.

However, there are outside factors that influence accuracy that Garmin cannot control. These factors include weather, satellite, golf course upgrades, and remodeling.

Design – Rating 4.3/5

The Garmin S20 golf watch look slightly dated. Although you can wear it off the golf course for daily use, it does not compare well to most watches.

The square-shaped watch is flat and only a little bigger than a regular watch. It attaches comfortably to your arm with its perforated silicone bands.

You are not specifically buying the Garmin S20 golf watch for an appealing look but rather for its intuitive golf functionality on the golf course.

The 1-inch X 1-inch monochrome LCD screen will display the yardage to the front, middle, and back of the green, location of hazards, layup areas, to guide you through your round.

It does this even in bright sunlight!

Battery – Rating 4.8/5

Constant GPS tracking, use of the backlight, and freezing weather can drain the battery rapidly. Power save mode will increase battery life.

According to Garmin, you can expect 15 hours of battery life in GPS mode and up to eight weeks without GPS usage.

The battery requires approximately 2 hours for a full recharge.

Fitness, health, and activity tracker – Rating 4.7/5

Garmin Approach S20 is compatible with the Garmin Connect fitness-tracker program.

Parameters that are tracked include the odometer, heart rate monitor, timer, and your sleeping patterns.

Portability – Rating 4.8/5

Weighing in at only 1.5 ounces it is extremely lightweight and will not wear you down out on the course.

Is Garmin Approach S20 Waterproof? – Rating 4.9/5

The Garmin Approach S20 is rated 5 ATM for water resistance and can thus withstand submersion in up to 50 meters of water.

Warranty – Rating 4.5 / 5

Garmin’s non‐aviation products offer a 1-year consumer limited warranty against defects in materials or workmanship from the date of purchase.
