A device operable as an electronic shark deterrent has a high-voltage pulse signal waveform generator for pulses to be applied to electrodes when immersed in water to deter sharks and other aquatic creatures. A preferred output waveform has a train of pulse bursts of alternating-polarity pulses in a series. Preferably, the timing intervals between pulses are of irregular duration, the amplitudes of pulses are varied to be irregular, and the interval between pulse bursts is kept to less than about 5 seconds, in order to be more effective as a shark deterrent signal. The device has the signal waveform generator enclosed in a thin, planar case mounted to a belt connector and a fastener strap for attachment to a part of a user's body. |
