What is tsi golf?

TSi (Titleist Speed Project) golf is a line of drivers and fairway woods from the Titleist brand that is designed to provide maximum distance and speed for golfers. The TSi line includes four different models: TSi1, TSi2, TSi3, and TSi4. Each model is engineered for specific player profiles, swing types, and preferred shot shapes. The TSi drivers feature an aerodynamic shape, adjustable weighting, and a precision-milled face for optimal launch and spin control.

The TSi line is used by professional golfers on the PGA Tour and has received high praise from golfers of all skill levels.
