## Abstract

The present disclosure relates to a golf putter fitting device and method of use thereof. Particularly, the golf putter fitting device includes a thin pad having a mirrored surface disposed on a top side portion of the thin pad and two slots disposed along a lengthwise section of the thin pad, a sliding bar disposed on the mirrored surface and coupled to the two slots, and a plurality of reference markers disposed on the mirrored surface for determining a putter selection zone from a plurality of putter zones.

## Claims

### Claim 1

A golf putter fitting device for selecting a golf putter type for a golfer comprising:
a thin pad having a mirrored surface disposed on a top side portion of the thin pad and two slots disposed along a lengthwise section of the thin pad;
a sliding bar disposed on the mirrored surface and slidably coupled to the two slots; and
a plurality of reference markers disposed on the mirrored surface for determining a putter selection zone from a plurality of putter zones by sliding the sliding bar to a reference point disposed on the mirrored surface corresponding to a visual alignment of a reflection of a dominant eye of the golfer to the reference point when the golf putter fitting device is placed on a ground surface with the mirrored surface facing the golfer at an address position and directly viewed from above by the golfer and a face portion of the golfer is reflected on the mirrored surface, wherein the golf putter type is selected based upon the putter selection zone and the dominant eye of the golfer.

### Claim 2 (depends on 1)

The golf putter fitting device of claim 1, wherein a ball slot is disposed along an edge portion of the thin pad.

### Claim 3 (depends on 2)

The golf putter fitting device of claim 2, wherein the plurality of reference markers a horizontal target line centrally disposed along the lengthwise section of the thin pad, two vertical putter lines disposed proximate to the golf ball slot, a first array of dots disposed on one side of the horizontal putter line, and a second array of dots matching the first array of dots, wherein the horizontal target line separates the first array of dots from the second array of dots, a first horizontal row of dots adjacent to the first array of dots, and a second horizontal row of dots adjacent to the second array of dots.

### Claim 4 (depends on 3)

The golf putter fitting device of claim 3, wherein the first array of dots, second array of dots, first horizontal row of dots, and second horizontal row of dots are separated into groups of three equally divided columns representing the plurality of putter zones.

### Claim 5 (depends on 1)

The golf putter fitting device of claim 1, wherein a slip resistance surface is applied to a bottom side of the thin pad.

### Claim 6 (depends on 1)

The golf putter fitting device of claim 1, wherein the dominant eye of the golfer is a left eye or a right eye of the golfer.

### Claim 7 (depends on 1)

The golf putter fitting device of claim 1, wherein the golf putter type includes a face balanced putter, a slight toe hang putter, a moderate toe hang putter, or a high toe hang putter.

### Claim 8 (depends on 1)

The golf putter fitting device of claim 1, wherein an alignment pad is magnetically coupled to the golf putter fitting device via magnetic members disposed along an edge portion of the alignment pad and an edge portion of the golf putter fitting device.

### Claim 9 (depends on 8)

The golf putter fitting device of claim 8, wherein the alignment pad includes a reflecting surface disposed on a top portion of the alignment pad and a horizontal reference line disposed on the reflecting surface.

### Claim 10 (depends on 8)

The golf putter fitting device of claim 8, wherein the golf putter fitting device and the alignment pad act as visual alignment training aids, allowing the golfer to view and align a reflected image of shoulders and arms of the golfer to a horizontal target line disposed on the golf putter fitting device and a horizontal reference line disposed on the alignment pad.

### Claim 11

A method of selecting a putter type for a golfer via a golf putter fitting device having a thin pad, a mirrored surface disposed on a top side portion of the thin pad, two slots disposed along a lengthwise section of the thin pad, a sliding bar disposed on the mirrored surface and slidably coupled to the two slots, and a plurality of reference markers disposed on the mirrored surface, the method comprising:
placing the golf putter fitting device in front of the feet of the golfer with the mirrored surface facing up, wherein a reflection of a dominant eye of the golfer appears on the mirrored surface and visible to the golfer at an address position;
positioning the sliding bar to a reference point disposed on the mirrored surface corresponding to a visual alignment of the reflection of the dominant eye of the golfer to the reference point;
determining a putter selection zone from a plurality of putter zones based on a position of the sliding bar to the reference point; and
selecting a putter type based upon the putter selection zone.

### Claim 12 (depends on 11)

The method of claim 11, wherein a ball slot is disposed along an edge portion of the thin pad.

### Claim 13 (depends on 12)

The method of claim 12, wherein the plurality of reference markers a horizontal target line centrally disposed along the lengthwise section of the thin pad, two vertical putter lines disposed proximate to the golf ball slot, a first array of dots disposed on one side of the horizontal putter line, and a second array of dots matching the first array of dots, wherein the horizontal target line separates the first array of dots from the second array of dots, a first horizontal row of dots adjacent to the first array of dots, and a second horizontal row of dots adjacent to the second array of dots.

### Claim 14 (depends on 13)

The method of claim 13, wherein the first array of dots, second array of dots, first horizontal row of dots, and second horizontal row of dots are separated into groups of three equally divided columns representing the plurality of putter zones.

### Claim 15 (depends on 11)

The method of claim 11, wherein a slip resistance surface is applied to a bottom side of the thin pad.

### Claim 16 (depends on 11)

The method of claim 11, wherein the dominant eye of the golfer is a left eye or a right eye of the golfer.

### Claim 17 (depends on 11)

The method of claim 11, wherein the golf putter type includes a face balanced putter, a slight toe hang putter, a moderate toe hang putter, or a high toe hang putter.

### Claim 18 (depends on 11)

The method of claim 11, wherein an alignment pad is magnetically coupled to the golf putter fitting device via magnetic members disposed along an edge portion of the alignment pad and an edge portion of the golf putter fitting device.

### Claim 19 (depends on 18)

The method of claim 18, wherein the alignment pad includes a reflecting surface disposed on a top portion of the alignment pad and a horizontal reference line disposed on the reflecting surface.

### Claim 20 (depends on 18)

The method of claim 18, wherein the golf putter fitting device and the alignment pad act as visual alignment training aids, allowing the golfer to view and align a reflected image of shoulders and arms of the golfer to a horizontal target line disposed on the golf putter fitting device and a horizontal reference line disposed on the alignment pad.
