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 period

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.

A parachute including a main canopy and a reserve canopy and having secured to the main riser of said main canopy a homing device having means for providing an audible signal, comprising in combination, a piezocrystal, a power source for said piezocrystal, switch means to selectively provide electrical connection between said piezocrystal and said power source, activator means, said activator means being placed in proximity to said switch means, wherein the presence of said activator means prevents said switch means from completing said connection and the removal of said activator means allows said switch means to complete said connection, means to periodically interrupt the flow of current from the power source to said piezocrystal thereby producing a signal ON period of at least about two seconds and a signal OFF period of at least about two seconds, wherein said switch means is held in the open position by a break away cable portion of a release mechanism which causes said main canopy to break away.
