    • The retrieval device for tethered articles is a portable, compact device well suited for use by solo players practicing various aspects of sports. For example, the device may be used by a football kicker to retrieve a tethered ball after each kick, thereby saving the player considerable time in retrieval efforts and precluding the need for a second person to return the ball. The device may also be used by baseball or softball players for pitching, batting, and/or throwing practice, soccer players, etc. as desired. The device may also be used to retrieve articles other than sports balls. The device includes an electrically powered reel which allows the tether line to pay out with virtually no restriction when the electrical circuit is inactive, but which engages a retrieval reel when activated. Automatic and emergency stop switches are also provided. The device is preferably powered by one or more rechargeable batteries.
