ABSTRACT:
The invention relates to a homing device having means for providing an audible signal. A piezocrystal is powered by a single battery or a plurality of batteries in series, so as to provide a voltage of at least about 12 volts D.C. whereby the piezocrystal produces at least 80 db during the ON periods. The means to selectively provide electrical connection between the piezocrystal and the power source, is a magnetically activated reed switch held in the open position by the proximity of a magnet. Means is provided to periodically interrupt the flow of current from the power source to the piezocrystal thereby producing a signal ON period of at least two seconds and a signal OFF period of at least two seconds. The homing device can be totally enclosed within a weather proof container with a magnet positioned outside of the container proximate the reed switch. The homing device is secured to the riser of a main canopy riser and the magnet is secured to a ripcord. The break away rip cord cable is attached to a canopy release mechanism which separates the main canopy from a harness. The homing device is contained within a housing which is less than one half inch thick by less than two inches wide by less than three inches long.
