Which is Better? S10 VS S20

Since we have talked about mostly all the parameters about the S10 and S20 entries by Garmin. The Garmin S20 features an Auto shot round analyser that helps you to track your shots (viewing shot locations after the round is over).

Even the fitness tracking features of S20 have an upper edge over the S10. If you are worried about battery life then again the S20 takes the first position. Slope compensation is something both these miss out. The S10 is certainly an affordable device than the S20.

Clear Cut Winner

But overall, with all its qualities and features, the trophy for the best golf watch goes to Garmin S20, if you can play slightly higher.
