Garmin's Approach CT10 automatic golf club monitors employ the latest GPS technology to help you stay on top of your game. Each compact monitor screws into the top of your club's handle and automatically turns on when you take your club out of your bag. Pair your compatible Garmin GPS golf watch with the monitors and it'll automatically show you the average distance you hit for each club right on the watch's face. With each swing, you'll develop a deeper understanding of how your clubs might be more useful within certain situations.
To install, simply screw the Approach CT10 monitor into the pinhole at the top of the grip. Each monitor measures 9/16" tall, weighs 0.3 ounces, and includes a user-replaceable, coin-style 3-volt battery. Garmin's design ensures the monitors won't activate until you take your club out of the bag, so you can expect an average life expectancy of 4 years per battery. And the monitors are waterproof so you can play without fear in inclement conditions (or if you're the type who throws their clubs into the nearest water hazard when frustrated).
Once you've installed the Approach CT10 monitors on your clubs, pair them with your compatible Garmin golf watch to register the type of club (putter, 9-iron, pitching wedge, etc.) before you start taking shots. Your Garmin golf watch can pair with up to three monitors at one time if you need to compare clubs before making your selection. The monitors will automatically record the distance shot, locations, and club types to the watch as you progress through the game, so you can concentrate on the next move. Gimme putts, missed shots, and penalty strokes are not recorded, so you'll need to manually enter them. Don't worry: the monitors even know when you're taking practice shots, so they won't get recorded either.
For an even more thorough statistical analysis, the Garmin Golf smartphone app keeps track of your performance over time in a number of ways, so you can pull up past games on your phone and see where you need more work and where you're improving. It covers accuracy to the fairway or green and for drives, approach shots, chip shots and putting, and allows you to set baselines to see how you're faring relative to other players in your group.
