There is a very specific reason why, if you walk down the range at any Tour event, every single professional uses a launch monitor when practicing and warming up. They don't rely on guesswork, they demand precise data to measure their carry yardages for the day and ensure their swings are completely dialed in before they ever step onto the first tee.
I usually like to keep my core setup for my practice consistent, laying down some alignment sticks to keep things fairly neutral, but after a particularly frustrating few weeks not being able to translate my swing on the range to the course, I decided to fundamentally change how I practice by integrating the Foresight GC3 Launch Monitor, and I’m already noticing the difference.
