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.

Abstract
A shock detector having an electrical detector having a set of water immersible electrodes for detecting hazardous water conditions through the 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 and then providing an alert to the existence of hazardous electrical conditions in the body of water which in some cases may transmitted to a power source to shut off a power source thereby removing the hazardous water condition.

6. The method of determining the presence of an electrical field in a body of water where the electrical field is sufficient so as to injure or kill a person entering the body of water comprising:
inserting a pair of water electrodes into a body of water before a person enters the body of water and measuring either a voltage differential between the water electrodes or a current flow between the pair of water electrodes and sounding an alarm if either the voltage differential or the current flow is sufficient to cause injure or electric shock drowning. - View Dependent Claims (7, 8, 9, 10)

11. A shock detector comprising:
-
a housing; an electrical detector located in said housing; a first water electrode for at least partially immersing in a body of water, said first water electrode in electrical communication with said electrical detector while being electrically isolated from said housing; a second water electrode for at least partially immersing in a body of water, said second water electrode in electrical communication with said electrical detector while being electrically isolated from said housing; an indictor comprising an AC ammeter for alerting a person of the presence of an electric field in response to a signal from the electrical detector; and a current rod wherein the first water electrode connects to a first end of the current rod and the second water electrode connects to an opposite end of the current rod with the electrical detector responsive to the presence of a current in the current rod when the current rod is immersed in a body of water having the electrical field. - View Dependent Claims (12, 13, 14, 15, 16, 17, 18)
