Small enough to fit in your pocket. Smart enough to change the way you practice.
The Stack Radar gives you instant club speed feedback on every swing. Use it during speed training sessions, on the range, or even when you're hitting balls on the course.
When you can measure speed instantly, every swing becomes more intentional.
Pair it with TheStack App in Wedge Mode and it gets even smarter.
The app calls out target distances and scores your shots in real time, turning wedge practice into a data-driven, gamified training session designed to sharpen distance control from inside 150 yards.
