The Impact Cube has 4 sides with 4 Impact positions:
The Wedge Lean side is slanted so a forward leaning Wedge matches the angle.
There is a 7 iron lean and a vertical Driver lean side, too.
There is also a round side.
Then the magic happens! Flip the Impact Cube on its top and you have a side (the Wedge Lean) that is slanted toward you. Set the ball "under" the slant and it is the ideal tool for teaching an inside attack angle and preventing the "over the top" move.
The Impact Cube was developed with Ed Bowe, Director of Instruction at Amelia Island. "I use it in every lesson. It helps people see the impact angles and learn the correct impact feel … fast."
