ABSTRACT:
A resiliency and relative hardness of a golf green is tested by the apparatus having a support base mounting a measuring rod orthogonally oriented relative to the support base and coaxially aligned with a support base bore. A golf ball sphere slidably directed through the bore and its resistance effected by contact with an underlying golf green is measured by relative projection of the sphere within the golf green and simultaneous deflection of a dial indicator foot measuring projection of the golf ball sphere into the golf green.
