Manufacturer: Surpass Golf Product Name: MAGIC IMPACT KZ#1 Putter Headcover: None Length: Approx. 33.5 inches Total Weight: 524g Grip: Original round grip This was my trusty companion that earned me quite a bit at the Olympics! This is a putter featuring the KZI insert, praised as a revolution in putters, developed by Hoshitani, the author of "The Law of Putts That Go In!" and a scientist researching the physics of putting. It boasts absolute straight-line performance!! Ball dwell time has increased by over 200%! This number revolutionizes previous rolling! Previously, you might have experienced: - The ball cutting short before the cup - The ball stopping before the cup - Difficulty with distance control → The "KZI insert" will sink your putts. For a short putt of about 1.5m, when you impact the ball with the face of a conventional putter, the contact time is about 0.005 to 0.0007 seconds. In terms of the putter's travel distance, this is 0.7mm. On the other hand, with the KZI insert, the contact time is over 200% of the conventional type, and the putter's travel distance extends to 1.6mm. This action increases the amount of topspin, allowing you to hit the ball with better roll and stable directionality. I'm listing this because I've accumulated too many putters and it's seen less use recently, so I'd like to pass it on to someone who will cherish it. There are minor scratches on the sole and shaft, but they should not affect play. Please only consider if you understand that this is a used item.
