With its auto-shot measure function, this device will accurately determine the distance of your tee shot, your putts and your other shots, and save them for post-round analysis on the Garmin golf App.

In addition to automatic shot measuring, the X40 is also a beast at measuring yardages. The moment you set it up at your local golf course, it will give you the yardage to the front, the middle, and the back of the green on your first hole. It will also automatically indicate the par number. With this kind of information, you can tweak your game and get better scores for every round of golf you play.

Obviously, like many other Garmin watches, this device will automatically record your scores. It will also automatically advance to the next hole and show the new distances and the par number. This means there is no need for you to extensively tinker with the X40 on the course to get it to tell you the right stats and course information. Simply move around the course as you normally do and you will get all the information you need in just one or two clicks of the navigational button.

Speaking of clicks, the design of the Garmin X40 is such that it is very easy to use since it has just a single navigational button and a touchscreen. The screen is very sensitive and has a high contrast display that makes it easy to view even under the midday sun. Although previous X40 screens cracked after several months of use, the company seems to have improved on this aspect of the device and they now last much longer.

The Garmin Approach X40 also provides game-changing information that you can use to get good scores on dogleg holes or holes with challenging hazards.

In addition to being a very good rangefinder and game tracker, the Approach X40 is also a pretty good fitness tracker. It is packed with multiple sensors to monitor various aspects of your fitness on and off the course.
