Compression
Compression is a measurement of how much a golf ball deforms (compresses) when a load is applied to it. It is an indication of how a golf ball feels at impact. The lower the rating the more the ball deforms and feels softer, the higher the rating the less the ball deforms and feels firmer.
Manufacturers often address the golf ball’s core compression when talking about its construction and design. The core is typically referred to as the inner most part of the golf ball in a two- or three- piece construction.
