The Tour Striker PlaneMate is a great training aid to help simplify your swing. Hitting pure short shots starts with being able to feel and understand the radius of your swing.
Start to develop these feelings by closing your eyes while you set up to the ball. You’ve found your radius when you feel light pressure on the band. Sustain this amount of pressure throughout your entire swing. Once you’ve established your radius, all that’s left to do is determine the speed of your club and collect the golf ball.
