This product helps players monitor ball position, swing path, and angle of attack. The premise is simple - hit the ball without hitting the board.
A common swing pattern for beginning and mid-level players is to swing outside-in where the hands move away from the body and the clubface arrives at the ball prior to the hands. With the compression board the player will be able to see his or her swing path and works on pinpointing the bottom of the swing arc. If the player shallows out too early and tries to scoop the ball then they will hit the board.
Aside from being portable, the Compression Board is very unobtrusive when using it on the range and is not visually distracting. It is made of unbreakable polycarbonate Lexan and is even quite useful for putting where the setup and strokepath can be monitored. It also makes visualizing and committing to the aimline on breaking putts easier.
