1. A shock detector for detecting a hazardous water condition comprising:

  • a sensor for determination of the presence of either an electrical current in a body of water, a voltage in the body of water or a voltage gradient in the body of water that is sufficiently great so as to injure or kill a person entering the body of water;

    a ground electrode for engaging with soil proximate a body of water;

    an electrical conductor connecting said ground electrode to said shock detector;

    a first water electrode for immersing in a body of water;

    a second electrical conductor connecting said water electrode to said shock detector;

    an electrical detector comprising a voltmeter located in said shock detector for measuring a voltage between the ground electrode and the first water electrode; and

    an alarm for alerting a person that the measured voltage between the ground electrode and the first water electrode has exceeded a dangerous threshold that would injure or electrocute a person.
