AI-DUAL JAILBIRD MINI 1/2-BALL DB 推桿

This Ai-DUAL mini putter features a half-ball alignment design intended to improve setup accuracy by making it easier to notice misalignment between the clubface and ball. It uses two types of resin in the insert, with a soft surface and hard inner layer, designed to stabilize ball speed and generate more forward spin.

• The description claims that the half-ball design improves station alignment and stability.
• The description claims that a study involving 52 participants and 1,060 putts showed improved face alignment and stability at distances around 2 meters.
• The description claims that the Ai-DUAL insert is designed to produce consistent forward spin regardless of impact location.
