Abstract

The invention is a putter training device which comprises a laser, housing for the laser, with to connect the laser to a battery source, a battery source, and a trigger. The housing, incorporating the laser is affixed to the putter face, the wire is wound around the shaft of the putter and the battery source/trigger is affixed to the grip of the putter. The invention is designed to be removed and reattached easily and without need for frequent adjustment or calibration. Proper use of the invention simultaneously addresses three common problems for golfers: aim, effective loft, and inconsistent and off-center impact points. The device can be used indoors or out and with or without a ball. The Trigger and the laser can communicate using RF transmissions in an alternative embodiment.

Claims

1. A putting training device comprising:

a base unit;

a switch unit; and

a laser projector, where said base unit has two legs which form an upside down U shape where said laser projector is located at top center between the two legs, where said base Unit is connected to said switch unit through a connection that runs through one of said legs.

2. A putting training device as in claim 1 where said base unit and switch unit are connected by an RF means.

3. A putting training device as in claim 1 where said laser projector is a laser diode.

4. A putting training device as in claim 1 where said switch unit has a trigger.

5. A putting training device as in claim 1 where said base has a viewing port through which the ball can be seen.

6. A putting training device as in claim 1 where said laser projector projects a beam of light perpendicular from the putter face, which the base unit is attached to, at a target.

7. A putting training device as in claim 1 where said base unit has a loft adjustment.

8. A Putting training device as in claim 1 where said switch unit has a power Source.
