When you hear a second "click" above your head, you have made a precise follow-throw and finish. Control Scale This product uses international patented technology (USA, China, Korea, Japan) to improve flight distance and head speed. This product is designed to allow you to practice your swing while adjusting the speed. Adjustable control scale allows golfers to adjust and practice club head speed from 11 to 110 MPH. You can also adjust the distance from 25 to 280 yards. With control scales, the ACK uses a dual-click system to provide instant feed to help you develop the perfect rhythm and tempo for wedges, irons, woods, and drivers.  How to use Adjust the control scale to desired swing speed (11-110 MPH) or yards (25-280 yards). Start of back swap and down swap Complete swing with follow-through When practicing with a swing trainer, adjust the scale to the required flight distance, then practice repeatedly while adjusting the swing speed until you hear a sound or the point light flashes on the LED on the head in the impact zone, or until it becomes stable.  On the other hand, for distances of 90m or more, you need to maintain a certain swing speed and select a club according to the distance. I will do the following. Similarly, when practicing on a swing trainer, choose the club head speed that suits you and practice repeatedly to master it. Do not forcefully increase the head speed and make drastic changes.   Note: If the first "click" is too quick, the swing is too fast. If the first "click" occurs after the ideal ball position, the swing is too slow.  Specs & Features Length 28 inches Adjustable control scale accommodates clubhead speed and yards Measuring swing speed: 11 - 110 MPH Desired distance: 25 - 280  Yards Dual clicks for quick feedback Improves the rhythm and tempo of your desired swing speed Great for warming up & stretching
