Performance

The Garmin Approach S12 performs admirably in a range of conditions and use cases. Its GPS accuracy is precise, with yardages to the front, back, and middle of the green, as well as to hazards and doglegs, all available at a glance. This is essential for golfers who want to ensure they’re hitting the right distance for each shot.

GPS Accuracy

One of the most crucial aspects of a golf GPS watch is its accuracy. The Garmin Approach S12 excels in this area, providing yardages that are accurate to within a yard of traditional yardage books. This level of accuracy can be crucial when determining the distance to the green or avoiding hazards.

Scorekeeping and Data Sync

The scorekeeping functionality is simple to use and eliminates the need for pen and paper. You can input your scores directly onto the watch and then upload them to the Garmin Golf app. This makes it easy to track your progress over time, and the app also allows you to compete with other golfers globally through leaderboards.

Display and Usability

The 0.9-inch high-resolution display is not just sunlight-readable but also provides clear, crisp data in a straightforward layout. This means you won’t have to struggle with reading the screen on bright days. The watch is designed to be user-friendly, with intuitive button operations that don’t overwhelm users with unnecessary complexity.
