Cobra Optica SL-01 Putter: New for 2007, the Cobra Optica putter range offers superior alignment, superior feel, and uses cutting-edge fibre optic technology. Cobra brings the science of putting to a whole new level with the introduction of the new Cobra Optica range, the first putters to use Fibre Optic Technology to help golfers align putts with a new level of confidence and precision. The key to the Cobra Optica's superior alignment lies in the exclusive TRUGLO® Fibre Optic sight line that ensures your putts are always on target. TRUGLO sights are the brightest aiming points in the industry, enabling greater sight contrast for more accurate alignment. The unique tri-metal construction of the Cobra Optica Putter range locates most of the overall putter weight along the rear periphery of the putter head by means of the forged steel weight bar while a forged Aluminium 6061 body and milled face provide soft feel and true roll. An injected Urethane Body Cap further enhances feel for greater accuracy and distance control by dampening unwanted vibrations.
