Zach Johnson's SeeMore putter.
......If you check out the Tuesday pics, there's also a new putter that just came out yesterday and is first seen anywhere here at GolfWRX. Jason unboxed it as it was flown from the factory to him to show at the Sony. He said the production would be in Carbon and he's waiting to get a black one made for Zach to test out.Zach Johnson w/ SeeMore Putter and Iliac golf shirt
Also..neat bit of info I picked up. The putter Zach Johnson is using currently is not the one he won the Masters with. I guess he wore out the old one so Seemore made a new one for him. Thing is..Zach's putter head is extremely light. They had to shave down the sole to get it to 315grams.
