The latest driver from Titleist, the TSi4, is designed for players seeking “ultra-low-spin performance,” the company says, with the “advanced speed and distance gains” that have made the TSi2 and TSi3 drivers so popular on tour.
The key with the TSi4 is the center of gravity, which is the lowest in the TSi family and also the most forward. Titleist engineers say that enables the club to deliver less dynamic loft and less spin at impact. The clubhead is just 430 cc in size and boasts a classic, pear-shaped profile. The result, according to those same officials, is exceptional workability.
Adam Scott and Russell Henley are among the PGA Tour professionals who have put the TSi4 in their bags. But this driver is targeted at any golfer looking to reduce spin on tee shots, regardless of club speed.
Among the most interesting technological features of this stick is the ATI 425 titanium employed in the face. Made in a single foundry in Pittsburgh, Pennsylvania, ATI 425 is prized for its superior strength, elasticity and durability. It was developed initially for ballistic armor application and since has been used in the aerospace and commercial aircraft industries, including NASA’s Phoenix Mars lander. In the TSi4, Titleist representatives say, the material helps to launch drives with added speed and more consistent spin.
In addition, the clubhead is fashioned in ways intended to reduce drag, so that it moves faster through the air and generates more power at impact. And the driver is equipped with Titleist’s patented SureFit hosel, which uses 16 independent loft/lie settings along with headweight adjustability to create a more consistent and optimized ball flight through precision fitting.
