Abstract

The present invention provides a floatable golf ball for a driving range having excellent durability and good shot feel. The present invention relates to a floatable golf ball for a driving range comprising a core and a cover covering the core, wherein the cover has a flexural modulus (F) of 80 to 300 MPa, the golf ball has a specific gravity of not less than 0.5 and less than 1.0, and a deformation amount (D) of 3.0 to 6.0 mm when applying from an initial load of 98 N to a final load of 1275 N, and a ratio (F/D) of the flexural modulus of the cover (F) to the deformation amount of the golf ball (D) is within the range of 15 to 50.

Claims (4)
