This application discloses a novel protective case for Golf Documents. Golfers typically use protective cases for yardage books or green guides and consult these documents frequently during a round of golf. The claimed invention uses a means for securing one of the covers to the Golf Documents and locks it into place within a sleeve built into the case. This allows the other cover for the Golf Documents to rest unsecured within a separate sleeve. When a golfer consults their Golf Documents, one cover is secured in place and the other moves freely within a protective sleeve. This allows the golfer to repeatedly open and close the book without damaging the Golf Documents.

Systems and methods providing statistical analytics of golf performance for coaching including text, tabular, graphic, and image-based outputs that include trends information for the golfer, all based upon actual golf play on course situations, wherein the golfer inputs shot data during play, without interrupting the flow of the game, and uploads the shot data for analytics and review online, and wherein all information related to a given user are reviewable by an authorized coach user through a web-based coach access account. The system is further operable to provide the coach user rights for providing corrective or instructive feedback to the user, including visual recommendations such as modified target areas.

In a first aspect, a system for monitoring a swing is provided that includes (1) a swing measurement device adapted to couple to a swinging object and to output a signal indicative of a characteristic of the swinging object; (2) a wireless transmitter coupled to the swing measurement device and adapted to wirelessly transmit the signal output by the swing measurement device; and (3) a wireless device adapted to receive the wirelessly transmitted signal and to provide information regarding the swinging object based on the received signal. The wireless device is a cellular telephone or personal digital assistant (PDA). Numerous other aspects are provided.

Distance measuring devices and methods are included which may be used to measure and simultaneously display an accurate range of multiple targets such as the flags of a golf practice driving range.

Systems, apparatus, and methods for capturing data related to athletic performances. Some methods comprise displaying a site map for the performance and accepting a selection of a target for the performance. Various methods comprise estimating, based on the user location, the initial location of the object and recording data regarding the performance. Moreover, some methods also comprise using a satellite-based map as the site map. If desired, the estimating comprises sensing a pause in the changing user location. Some methods further comprise estimating a trajectory of the object using the initial location of the object and a portion of the trajectory. In some scenarios, methods comprise capturing a location of the object at the ending of the performance. The recording can further comprise capturing a video of the performance. Furthermore, these methods can comprise capturing subjective information regarding the performance.

The present invention relates to an electronic caddie-type golf assistance system and, more particularly, to an electronic caddie-type golf assistance system based on weather information calculated by inputting weather measurements into high-precision weather modeling. The golf assistance system according to the present invention comprises: a weather information acquisition device for acquiring weather information of a golf course; a wind information restoration device which models the weather information acquired by the weather information acquisition device to restore wind information; and an electronic caddie device for providing caddie information on the basis of the restored wind information. The golf assistance system according to the present invention may improve golfing performance by providing local-scale 3D wind information of a golf course.
