A swim paddle has a body portion and at least a strap member mounted on the body portion. Each socket includes a fitting end for an end piece and a nesting end. An air inlet connector with a hollow water channel is provided in the front part of the cavity of the shower head handle, and on the air inlet connector, air inlet holes are provided. This is particularly advantageous in the case where the item to which the tag is attached is very small, such that it is practically difficult to write information on the item itself or on the item casing. Time lapse indicating means substantially formed of a non-metal is arranged in the case between the dial and the receiving antenna for indicating the time lapse within the range of the opening. The control system additionally includes a knob rotatably attached to the housing’s exterior.
