摘要: A portable tennis scoring device having a flexible strap removably attached to a casing. The casing preferably contains a circuit chip and a battery; and the circuit chip is activated one or more of four activation switches, which cause information to be displayed (“activates”) in one or more of four separate displays. Additionally, two additional activation switches are used to either turn the unit on, turn the unit off, and/or reset one or more of the displays.
