Whether or not the GCQuad is worth it depends on your individual needs and budget. If you are a serious golfer who is looking to improve your game, then the GCQuad can be a valuable tool. It provides accurate data on a variety of metrics, including clubhead speed, ball speed, launch angle, spin rate, and carry distance. This data can help you identify areas of your swing that need improvement and track your progress over time.
However, the GCQuad is a significant investment. It costs $11,000 for the base unit, and you may need to purchase additional software or accessories depending on your needs. If you are not a serious golfer or are on a tight budget, then the GCQuad may not be worth the investment.
