Garmin Approach S10 Vs. Garmin Approach S20 Comparison Review

The Garmin S10 and S20 golf GPS watches certainly aren’t the new kids on the block but if you are looking for a solid and affordable golf GPS watch then you need to check both of these watches out.

We’re honestly pretty surprised that the Garmin S20 is still as affordable as it is. Perhaps it’s because subsequent models have come out to replace it. Still, it’s a steal at just around $200 with all the features it has.

But how does the Garmin Approach S10 golf GPS watch stack up in comparison? Find out in the following article.

Garmin Approach S10 Overview

The Garmin Approach S10 is certainly more bare-bones when compared to the Approach S20 but it still provides you with the essential information you need on the golf course.

What we appreciated the most when we tested the Garmin Approach S10 out was how simple the interface is. It doesn’t have a touchscreen. Instead it’s operated by a quarter of side-mounted buttons.

The watch face itself is only 11 millimeters which so it rests flat and comfortable on your wrist which is very important to us because we hate when a golf GPS watch actually encumbers your swing.

It’s simple to use and it looks pretty sleek too. In fact, it looks a lot like the Approach S20 except for the band.

The Garmin Approach S10 is also a steal at just around $150. We really liked the clear display and simple interface.

Garmin Approach S20 Overview

The Garmin Approach S20 is a bit more than just your normal golf GPS watch.

The S20 comes loaded with sports and healthy activity features which we will get into with more detail a bit later. However, right off the bat you should know that you will be paying about $50 more for the S20 mainly because of the fitness tracking features.

The S20 also has an improved battery over the S10. It lasts about 3 hours longer in GPS mode. Other than that though, the S10 and the S20 are similar in most respects. They both feature a comfortable silicone strap and have almost the same dimensions.

Even the resolution quality (128 x 128 pixels) is the same on these watches. Both the S10 and S20 have a clean, easy to read black and white display.

Anyone who wants a more modern smartwatch will do well with the Garmin Approach S20.

Garmin Approach S10 First Impressions

We really liked how clean and sleek the display looked as soon as we turned it on.

In fact, when we were using the Garmin Approach S10, we wondered how anyone uses a color display. There is just something about the classic black and white display that gives it a more sophisticated and certainly less busy appeal.

Key Features

The Garmin Approach S10 keeps it’s features golf-related which we fully support.

The Garmin Approach S10 keeps things simple and standard for the most part. It features a green view that shows you the distance to the front, back and center of the green, it’s preloaded with 42,000+ course maps, gives you distances to hazards, has a digital scorecard and an odometer.

You can also use it to calculate the distance of each of your shots but this is a manual feature. You basically have to walk to drive to your ball and input the distance traveled.

The Garmin Approach S10 is ready to go right out of the box and is intuitive even for non-tech savvy players.

Garmin Approach S20 First Impressions

The Garmin Approach S20 was a little harder to set up and switch from mode to mode than the S10.

Which makes sense, honestly. When you add to something you gotta lose something somewhere else, right? While the S20 has considerably more features than the S10 it is also less intuitive.

Key Features

 The S20 has more standard watch features and additional fitness tracking features.

For instance, we thought it was pretty surprising that the S10 didn’t have an alarm clock function. Oh well though, the S20 does.

It has all the same golf features as the S10 with additional fitness tracking features like a pedometer, swim timer, movement alerts, daily step goal alerts and it tells you how many calories you’ve burned during different activities.

The S20 aims to have use outside of the game of golf.
