he m5x bi metal large mallet is precision milled from Carbon Steel with a proprietary multi-layer black gunmetal finish for striking and lasting beauty. It also features a milled aluminum insert with horizontal grooves for enhanced feel and roll. Milled in the USA and features SeeMore’s new RST RifleScope technology alignment system. The 2 white lines are milled perfectly parallel to the face of the putter, creating a perfect "gun sight" effect where the golfer is assured of being square to the intended target line when the white lines are visible and the signature red dot is hidden. If the red dot becomes visible at address, then the putter face is either open or closed, or the loft is not optimal. The golfer knows that when the 2 white lines are visible, and the red dot is hidden, that the putter is not open or closed, and that the putter is fixed in a neutral position where the loft of the putter head will be optimal for perfect roll on every putt. Finally, the golfer also can be confident that by lining up the 2 white lines, and making sure the red is not visible, that his eyes and shoulders and hips will all be square to the intended target line. This means that the golfer will enjoy a much greater probability of making a consistently perfect stroke with each and every putt, leading to more made putts and lower scores due to improved putting.
