Abstract: A collar for a bat. The bat includes a barrel, a taper extending from the barrel, and a handle extending from the taper opposite the barrel. The handle includes a knob and a grip. The collar is slideably positioned on the grip between the knob and the taper to secure the grip to the handle. The collar includes a circumferential wall, a plurality of securing members positioned on the circumferential wall to engage the grip, and the collar is slideably preferably positioned on the handle between the grip and the taper. The securing members removably secure the collar to the grip and in turn removably secure the grip to the handle.

Abstract: An apparatus for practicing a method of determining the effective putter loft of a golf putter as swung by a particular golfer in which the putter has a curved face unit placed on the hitting surface and the putter is then swung by such particular golfer against a hitting cylinder. The location of impact between the curved face and hitting cylinder provides data from which the effective loft can be determined.
