If you've ever spoken to a pro or had golf lessons, you'll know just how crucial it is that your golf swing is "on plane".
By simply placing another golf club, an alignment rod or drawing a chalk line on the ground or driving-range mat, the Laser Plane Trainer will instantly show you whether your swing is over or under plane.
Simply attach to the bottom of your golf club and switch on. The Laser Plane Trainer will give you 3 reference points during a full swing to see if your on plane. The backswing, the downswing and the follow through.
