Dan Landman is the founder of Spoiler Golf and the inventor of the Spoiler OG Putter.

The idea for Spoiler Golf came from putting with a wedge and, by extension, learning how pure the ball rolled from the leading edge of a Wedge vs the traditional “flat face” of a putter. Dan and Spoiler Golf believe a better roll of the golf ball unlocks a better putting experience, and so they set out to change the face of putting for everybody.

Dan's suspicion of a purer roll of the ball coming off the leading edge of a club vs the face of a putter was confirmed with research measuring the skid and roll of golf ball.  He and his engineer/designer doubled down on their efforts and built a number of "Leading Edge" putters.  Eventually after much trial and error they settled on the Spoiler OG - a putter where form truly met function.

Dan explains the Leading Edge technology as he introduces the Spoiler Putter.  He also addresses:

• The importance of putting and the role it plays in lowering scores
• How the Leading Edge technology works
• How Leading Edge technology enhances focus and concentration on the process of excecution on the greens
• Impact location for success in distance control and accuracy 
• Mitigating the yips with Leading Edge technology, and
• How the Spoiler gives instant feedback for quicker, more purpose-driven learning.

He also elaborates on the following game improvement topics:

• The big picture golf swing idea for better ballstriking
• Efficient power production
• The "Goat" delivery position
• Learning good clubface control with the trail-hand
