A putting training device includes a fixing hub including a shaft retainer combined with a putter shaft; a first rotary support and a second rotary support coupled to the block part at both sides of the putter shaft, respectively; a first support bar having an upper end supposed to be held in an underarm of a user and the other end rotatably coupled to the first rotary support; a second support bar having an upper end supposed to be held in the underarm of the user and the other end rotatably coupled to the second rotary support; and an angle adjuster coupled to the first support bar and the second support bar over the first rotary support and the second rotary support to be able to adjust an angle between the first support bar and the second support bar.

A golf club fitting apparatus and a method for fitting using the apparatus are provided. The golf club fitting apparatus may be attached to a golf club and provide fitting information including effective lie angle, effective loft angle, stroke plane, and aiming verification information. That golf club fitting apparatus includes a first opening for receiving a shaft, second openings for receiving a collimated light source, third openings for receiving angle indicators, and a recess for securing the collimated light source in an alternate configuration.

Systems and methods for motion capture and analysis are described. The system may include a motion sensor unit configured to capture data associated with movement of an object. The motion sensor unit is configured to be directly or indirectly coupled to the movement object at a first location. The system also includes a processor to process the captured data to determine one or more values and to translate the data and/or values to correspond to a second location on the movement object located away from the first location. The data and/or values, including translated data and/or values, may be transmitted by wireless transmitter and displayed by a display unit.

A golf club head has a body defining a ball striking face. The body further has a rear portion comprising a plurality of side walls and a planar lower portion. The plurality of side walls extend downward from a top of the golf club head towards the planar lower portion. The body further comprises a cover extending over the rear. The body further defines a gap between the cover and the planar portion.

A golf club head is provided having a club body having a front portion, a rear portion, a toe portion, and a heel portion. The club head also having a central portion connected with the front portion. A frame is connected with the central portion configured to provide a lightweight crown portion being located above an offset plane.

The present invention provides a putting guide capable of correcting a posture when putting, checking a contact angle between a putter and a golf ball, correcting a posture of an exerciser during a putting practice, and checking a focusing point that the exerciser watches. The putting guide for putting practice includes a hitting part, a rod part connected to the hitting part, and a front part formed on an end of the rod part.

An equipment fitting system that measures swings by a user of different pieces of equipment with inertial sensors, and analyzes sensor data to recommend which piece of equipment is optimal for the user from among those tested. Illustrative applications include fitting of baseball bats and golf clubs. Swing metrics calculated from sensor data may include an acceleration metric, a speed metric, and a momentum metric; these metrics may be combined into a metrics score for each piece of equipment. Other factors may be included in an overall score, such as the user's subjective score for each piece of equipment, and ratings from experts or other consumers. Users may assign the relative importance for the different factors to calculate an overall equipment score.

Proposed is a digital direction-guiding apparatus for golf putting, which is a full body management system using cryogenic circulating cooling by the grafting of IT technology, the digital direction-guiding apparatus including a tri-axial MEMS sensor (100), a digital left and right inclination angle indication pointer (200), a digital up and down inclination angle indication pointer (300), a digital display unit (400), and a microprocessor (500). Thus, the digital direction-guiding apparatus including the tri-axial MEMS sensor, the digital left and right inclination angle indication pointer configured to indicate a putting direction, and the digital display unit configured to display the angle of a left and right inclination of the green may easily display a putting direction indication pointer and the angle of up and down inclination in a sophisticated digitized shape and may provide a thin apparatus.

A golf club fitting apparatus and a method for fitting using the apparatus are provided. The golf club fitting apparatus may be attached to a golf club and provide fitting information including effective lie angle and effective loft angle. The golf club fitting apparatus includes a lower surface that contacts a butt end of a grip, an upper surface opposite the lower surface, and a side surface connecting the upper and lower surfaces. An angle indicator is disposed at a predetermined angle relative to a shaft axis of the golf club so as to rest in a neutral position when the golf club is in a normal address position.
