Swing Catalyst vs. Balance Board
Measuring Ground Reaction Forces (GRF) vs. Training them.
Swing Catalyst 3D Motion Plates
Swing Catalyst is the gold standard for biomechanical golf analysis. Unlike pressure mats which only measure vertical force and COP, 3D plates measure shear (horizontal) force and torque (rotational force). It is a $15,000+ installation used by tour pros.
The GolfBT Board
The balance board cannot measure torque or shear force numerically. However, it trains the ability to apply them efficiently. You cannot keep the board level during transition without applying correct shear forces to counter the momentum of the club.
