This invention relates to the golf industry, it is comprised of 2 tees connected with a line that tethers the 2 tees together which minimizes the possibility of loss. The invention is used for teeing up, or elevating the golf ball from the ground when the rules allow so. The invention is designed to eliminate waste, save time, increase safety, and soften the environmental impact of traditional golf ball tee manufacture.

Systems, devices, and methods for an exercise mat that may include: a mat made of a cushioning material comprising a set of tick marks positioned along the longitudinal edges of the mat; and a set of horizontal lines defining a column of grids, and a set of numerical labels, where each numerical label is positioned near opposing ends of a corresponding horizontal line, and where the set of numerical labels do not indicate whole number measurements.

Systems for detecting a successful field goal are described herein. More specifically, the systems are directed at automated detection for a field goal attempt. The systems evaluate whether the football was kicked within the designated area (e.g., above the cross bar and between the two upright poles). The detection is performed through the use of cameras, lasers and detectors associated with the field goal post. In this way, the systems assist referees in determining the success of the field goal attempt.

An illustrative example embodiment of an ice hockey puck rebounder includes a rigid base with ends and side faces. At least one resilient member has a first surface secured to at least one of the side faces. A first surface of the resilient member is received against and supported by the side face of the base along its entire length. The resilient member comprises a rubber material having a durometer between 50 and 60. A second, outwardly facing surface of the resilient member presents a rebound surface for being contacted by an ice hockey puck. The resilient member consistently, resiliently deflects an ice hockey puck away from the resilient member.

A disc golf game system comprises two or more elongated poles adapted to be positionable upright on a surface. Each pole comprises two or more selectively connectable pole segments. At least one pole segment of each pole has circumferential indicia along at least a portion of a length of the at least one pole segment of each pole. The indicia forms a target area.

A golf swing training device comprising has a support base for contacting a support surface, such as the ground. There is a vertical support element extending upward from the support base having a lateral support arm transverse on the vertical support element with a relatively left side and a relatively right side. The lateral support arm has two directional arms extending in a forward direction away from the lateral support arms. The lateral support arm has a rotation-enabling connection to the vertical support element so that the relatively left side can be elevated above the relatively right side, and alternatively the relatively right side may be elevated above the relatively left side to alter the individual respective heights of the two arms.

A pin mount system for releasably mounting a sports net to a ground surface, for example a hockey net to an ice surface. The sports net includes at least one post having an end. The pin mount system includes: a pin having a proximal end and a distal end, the proximal end for positioning within the post, a resilient member such as a spring coil in compression to normally exert an extensive force to the pin to extend the distal end of the pin past the end of the post, and a handle operably connected to the pin to retract the pin against the resilient member. The pin is releasable from the ground surface in response to an amount of force applied to the sports net, and the sports net stays in place when minor force is applied, for example.

A sport combat training machine including a base assembly; a post; a shaft assembly having a spring adaptor; a mounting frame that mounts onto the post; a lower striking assembly having a first motor with a respective first adaptor having a first spring attached to a respective first lower striking arm; an intermediate striking assembly; an upper striking assembly including a second motor, with a second adaptor having a second spring attached to a respective first upper striking arm; and an electrical system having at least one computer configured with software to operate the first and second motors and a pedal for controlling the at least one computer. The intermediate striking assembly includes a body having a target area and at least one sensor. The sport combat training machine further includes a top plate assembly having at least one sensor.

A sporting device providing a rotating footplate and optional foot extension for a user to employ to practice a swing motion using a bat or club commonly used in sports.

A method of stabilizing a cornhole board on a support surface, comprising providing a cornhole board including an inclined board have a front, a rear, and a top with a target hole, one or more rear supports that support the rear of the inclined board at a height above the front of the board, and one or front supports that support the front of the inclined board; providing one or more stabilizing units for the one or more front supports that support the front of the inclined board and the one or more rear supports that support the rear of the inclined board, wherein the one or more one or more stabilizing units include one or more adhesion members that adhere to and stabilize the cornhole board relative to the support surface.
