Patent ID: 8376365

Claim:
A target member comprising: a housing having an outer surface which forms a section of a target surface during use, and a three dimensional degradable component having a plurality of surface sections suitable for use as a target, the degradable component arranged to be releasably retained within said housing relative to said outer surface for use so as to expose a first surface section of the degradable component for degradation through use of the target, wherein the housing comprises opposing housing portions, either or both of said housing portions having an interior recess within which the degradable component can be received such that, when the opposing housing portions are brought together, they define an enclosure shaped to closely surround the degradable component, and wherein the degradable component is selectively rotatable about a plurality of axes within said enclosure such that upon degradation of the exposed section of the degradable component of the target through use, the degradable component is repeatedly repositionable by rotation about one of its axes of rotation so as to present further, previously unexposed portions for subsequent use; and wherein the degradable component is spherical in shape and the plurality of surface sections suitable for use as a target adjoin one another on the surface of the sphere.
