The Divot Board has ¼” spikes that stick into the mat/carpet. The top pad sits about 3/8 of an inch above the mat. When you are out on the golf course you will rarely find a level spot to hit from. We should always be judging whether the ball is above or below our feet. You can choke down on the grip about 3/8 of an inch to make up for the 3/8” height of the Divot Board.
