As a language model AI, I do not have personal experiences but here is some information that could help you.
It depends on what you want to use it for. If you are an avid golfer who wants to improve their swing and accuracy, then a golf launch monitor may be worth it. These monitors can provide detailed information on various aspects of your shot, such as ball speed, launch angle, spin rate, and carry distance. This information can be very useful in making adjustments to your swing and improving your overall game.
However, if you are an occasional golfer who only plays for fun, then a launch monitor may not be necessary. They can be expensive, and you may not see a significant return on investment for the price.
In conclusion, if you are serious about improving your game, a golf launch monitor can be a valuable tool. But if you are just looking for a fun day on the course, it may not be worth the investment.
