A fingerprint provides evidence to find a suspected criminal. Similarly, the On-Mark can help you identify flaws in your golf swing.

It's easy enough to understand that distance, shot shape, and direction will all be adversely affected by erratic contact with the ball. But where on the face do you strike the ball? Are your shots going short right because you hit the ball on the toe, or are you hitting a thin heel'd shot & blocking the finish? On-Mark spray can give you the clues necessary to make a swing flaw arrest and conviction.

With approximately 100 applications of a light chalk spray, On-Mark provides a quick, clean solution to accurately locating your pattern of impact. In October, Golf Digest did extensive robotic testing of the latest drivers. What did they use to identify the driver's 'hot spots' and weak points? On-Mark of course.

On-Mark contains no CFC's and may be safely used indoors or out. And it's not limited to use with your driver. You'll find it just as helpful and just as important to use with your long irons, your 'scoring irons' (great for chipping & particularly your 1/2 & 3/4 wedge shots) and of course to improve pin-point sweet-spot contact when putting.

Use On-Mark to improve ball position, alignment, setup and swingpath by spraying lines in the grass. Designate landing spots or target rings on the green. On-Mark is game improvement in a can!
