The Stack System & The Stack Radar Combo

The Full Training Package The Stack Combo combines personalized speed training with the precision of the Stack Radar. This is the most efficient way to improve your golf game.
How It Works: The Stack Radar sends your swing speed data directly to TheStack App via Bluetooth while you train. No manual entry required. Small enough to fit in your bag, the radar also measures ball speed and estimated carry distance for use on the driving range.
The Stack Hardware:
Custom Dynamic Inertia: 5 CNC milled weights allow for 30 unique combinations to overload and underload your swing safely.
Engineered Shaft: Designed to mimic the feel of a driver for better transfer to the course.
The Stack App (1-Year Included):
Formulated by Dr. Sasho MacKenzie: The world's leading golf biomechanist.
Adaptive AI: Programs adjust automatically based on your "Stack Speed," "Distance Potential," and "Grit Score."
3-in-1 Training: Includes Speed Training, Gamified Wedge Sessions, and Guided Putting Practice.
Family Friendly: Train up to 20 local users under one login.
