Golfer's putting practice device

A practice mirror for improving golf putting skill, said mirror comprising:

• a flat planar mirror member having a generally planar upper reflective surface and a lower planar support surface;
• said upper and lower surfaces being generally parallel and providing a thin gauge structure, said flat planar member defining a substantially open, unrestricted putting surface for addressing and hitting the golf ball in practice putting;
• a target line image on said upper surface, said target line substantially bisecting said upper surface;
• and
• a positioning means for receiving a golf ball to be practice putted also bisected by said target line image;
• said positioning means being a channel extending from approximately the mid-point of one edge of said planar member to a closed end generally toward the center of said planar member, in alignment with said target line image, said channel having parallel edges spaced to define a width dimension wide enough to accept a golf ball while providing a preselected clearance between said golf ball and said edges of said channel such that when said golf ball is putted away from said closed end of said channel at any angle other than substantially parallel to said edges of said channel said golf ball ricochets against said edges of said channel before traveling out of said channel;
• said planar member adapted to be placed on the ground and supported on said support surface whereby said upper reflective surface is generally parallel to the ground, said upper reflective surface with said planar member on the ground adapted to provide a reflected image of the golfer and putter club whereby the golfer by viewing his reflection is able to detect and correct alignment errors that might otherwise go undetected, thereby improving his putting skill.
