Garmin Approach CT10

The Garmin Approach CT10 is the right shot tracking system for exactly one type of golfer: someone who already owns a compatible Garmin golf watch and wants to add automatic shot tracking without changing any other part of their setup.

For that golfer, it is an excellent choice. The sensors are the lightest in the category at 9 grams, attach cleanly to the grip end without affecting swing feel, and work fully automatically once paired. The user-replaceable CR2032 batteries last up to four years — you will likely replace the battery once in the entire ownership lifetime of the sensors, and you can do it yourself without returning the product. That is a meaningfully different proposition from Arccos, whose sensors have non-replaceable batteries and a 2-year guaranteed lifespan.

The Garmin Golf app integration gives you Strokes Gained analysis, club distance data, and access to tournaments and leaderboards. If you already use the Garmin Golf app for your GPS watch data, adding CT10 data to the same ecosystem is genuinely seamless.

The Starter Pack at £25.99 for 3 sensors is a sensible way to test the system before committing to the full set. Fit them to your driver, a mid-iron, and a wedge for a few rounds to understand whether the data changes how you play before spending £199.99 on the full 14.

The honest limitation is hard: if you do not own a compatible Garmin golf watch, none of this works. The CT10 is not a standalone system and has no path to use without the watch. Golfers starting from scratch with shot tracking should look at the Shot Scope CONNEX at £49.99, Arccos Smart Sensors at £224.99, or the Arccos Air bundle at £374.98, all of which work without a specific manufacturer's watch.
