Used by Professional Shingo Katayama BioMech arm lock putters are designed specifically for those struggling with the yips or golfers who find it difficult to keep their putts straight. Features Adopts an open stance and recommends using the core to stroke while keeping the arms, shoulders, and hands fixed. This eliminates fine muscle movements, achieving stable putting. The putter head is designed with a 12.5-degree forward lean, and when the hands are positioned forward when addressing the ball, the face becomes neutral. Alignment assistance features are also abundant; for example, the BioMech Max putter has a function that allows for accurate aiming by aligning the dominant eye with the hole in the putter. The AccuLock putter uses a unique optical alignment system to firmly position the dominant eye above the ball, allowing for a straight line of sight to the ball, putter, and path to the hole. Milled from aerospace-grade aluminum, providing a comfortable feel and excellent feedback. Effects Suppresses hand manipulation and integrates with the arms, enabling a stable stroke. The BioMech Golf Max putter, when used properly, is one of the most forgiving putters on the market and helps improve inconsistent putting. The BioMech AccuLock putter stabilizes the hands, arms, and shoulders, using core muscles and reducing the movement of the hands, arms, and shoulders, leading to more accurate putting. - Brand: BioMECH Golf - Color: Blue - Design: Novel - Material: Aluminum - Length: 39 inches - Accessories: Dedicated cover - Grip: winn - Condition: The grip surface is peeling (immediate replacement) Cover is starting to deteriorate The head is in good condition without major scratches Rust on the shaft has been removed.
