What is bunker sand made of? What is the best bunker sand?
January 13, 2022
The USGA has recommendations and guidelines for selecting the best bunker sand. These guidelines outline important characteristics of bunker sand including: Particle size; Particle shape and penetrometer value; Crusting potential; Chemical reaction (pH) and hardness; Infiltration rate; Color; and Overall playing quality. Overall, a bunker sand should have most of the particles between 0.25 and 1 mm, a high penetrometer value, good infiltration rate, angular or sub-angular shape, and low tendency to crust. This type of sand makes the ball remain in the bunker while not burying in the sand but also allows the bunkers to drain rainfall and remain playable.
