The PING Serene putters for women feature variable-depth groove technology.
PING reports its studies show a significant increase in ball-speed consistency when measured at nine points across the face insert.
The grooves are deepest in the centre and get gradually shallower out to the perimeter of the insert for predictable distances and accuracy, even when the ball is struck toward the heel or toe.
The insert is made of 6061-T6 aluminum for crisp feel and sound similar to a traditional steel face. Perimeter weighting in the 17-4 stainless steel heads and a balanced geometry add to forgiveness.
The Serene is available in Anser 2 (Slight Arc), B60 (Slight Arc), Shea (Slight Arc) and Craz-E Too (Straight) models.
