KZG, the No. 1 Custom Proline, introduces the OS-III Driver — engineered for golfers seeking to correct a slice and achieve higher, straighter drives with ease.
The OS-III Driver is specifically designed for mid to high handicap players who struggle with a slice or have slower swing speeds and are seeking a higher trajectory on their drives.
This driver provides forgiveness and slice correction, making it easier for golfers to hit straighter and higher shots consistently.
Key Features of the OS-III Driver:
- Offset Design with Closed Face Angle: Helps players square the clubface at impact, reducing the tendency to leave the face open and promoting straighter shots. Ideal for golfers with an outside-in swing path and a late release.
- Low Center of Gravity (CG) Weighting: Promotes an easy, high launch, making it ideal for players with slower swing speeds who need help getting the ball airborne. The higher trajectory helps maximize carry distance and ensures consistency off the tee.
- Heat-Treated Face Insert: Maximizes energy transfer at impact, producing a solid “crack of the bat” sound and offering a responsive feel that gives golfers immediate feedback.
- Gravitational Force (GF) Weight Port: Allows for additional flight correction. Adjusting the weight in the heel creates a draw bias, helping to counteract a slice and promote straighter ball flight. The GF weight system includes 8 weight options from 1.5g to 14g.
- Versatile Loft Options: Available in lofts up to 14°, offering excellent support for players seeking higher launch and greater forgiveness.
Whether you’re a professional fitter helping golfers play their best or a player ready to gain more consistency off the tee, the OS-III Driver delivers confidence-inspiring performance.
Available Models: RH, ML (10.5°), HL (12°), SL (14°)
MSRP starting at $349 USD depending on shaft selection.
