Launch it higher with less spin

I have a pretty simple drill that helps get the most out of your driver. I see people swinging the driver with a downward angle of attack, so they are losing distance. In order to get the most out of your driver, you want to launch it higher with less spin. A simple drill can fix this. I place a head cover 12-18 inches in front of the teed up golf ball. The goal is to swing without hitting the head cover. This will get the golfer to instinctively shallow out the angle of attack.
