A device including a golf ball that is configured to be operable for golf hitting practice. A cable assembly retains the golf ball during the golf hitting practice. A golf ball attachment eye segment engages the golf ball. A first compression sleeve is configured to join a portion of said cable assembly that is forming the golf ball attachment eye engaged with the golf ball. A cable eye segment is configured to be operable for engaging a stationary object. And a second compression sleeve is configured to join a portion of said cable assembly that is forming said cable eye.

The present disclosure provides a wireless signal transmitting ball to be used in practice or gameplay of a sport and/or other entertainment activities. The ball of the disclosure comprises a microprocessor unit configured to record, process, and transmit data to a paired device. Further disclosed is a method of actuating the ball between different modes. The ball could be used by players during practice to record data about their performance. The ball could also be used by players or game officials or referees to keep score, adjudicate and decide the gameplay. For example, the information about location of the ball could be used to track balls that could potentially be lost. Additionally, data about spin, trajectory, speed, force applied and the like could be used by players or broadcasters for gaining insights to add to viewing pleasure.

A 3-axis magnetometer inside a golf ball to detect the impact location on golf club heads that contain ferrous materials is disclosed herein. Key aspects of a golf shot are determined from within the golf ball itself. A magnetometer, preferably running at 85 Hz, inside a golf ball is able to measure spins of 5000 RPM. An integrated circuit comprises a gyroscope, a magnetometer, and a BLUETOOTH low energy (BTLE) radio, and at least one battery. A body is composed of an epoxy material, and the body encompasses the integrated circuit.

A golf swing training device for training a user to aim a golf swing in the desired direction includes a resiliently deformable body having a top surface, a bottom surface, and a perimeter surface extending between the top surface and the bottom surface. The bottom surface is configured to support the body on a support surface, and the body is elongated along a horizontal central longitudinal axis from a first end to a second end. The body is symmetrical about a vertical central plane. There is a divot penetrating the top surface adjacent the first end coupled to a compactable, resiliently deformable ball. The body is constructed of a low-density material and is configured to abruptly decelerate when moving through a quantity of air due to an air resistance force.

According to an exemplary embodiment, a distance measuring apparatus includes: a display unit and a sound output unit; a location acquiring sensor configured to acquire a current location; a slope sensor configured to measure a tilt angle; a distance measuring sensor configured to measure the straight line distance to a target; and a control unit configured to calculate a height of the target by using the tilt angle and the straight line distance, to calculate an attack distance by using a relationship between the height of the target, a landing angle, and the attack distance, and to output the attack distance to at least one of the display unit and the sound output unit.
