Shock awareness systems

A floating water shock awareness system for a body of water comprising:

• a buoyant housing having a waterproof compartment therein;
• an audio alarm;
• a visual alarm;
• a visual display screen;
• a processor containing information on water conditions located within the buoyant housing;
• at least two electrodes located on said housing with said electrodes contactable with the body of water proximate the buoyant housing;
• a voltage detector responsive to the at least two electrodes for determining a voltage gradient in the body of water proximate the buoyant housing;
• a GPS locater on said housing;
• a visual display on said buoyant housing with said visual display including a bar graph displaying a level of danger in the body through a water voltage gradient in relation to at least two zones where a water voltage gradient in a first zone is non harmful to humans who enters the body of water, and a water voltage gradient in a second zone can injure or kill a person who enters the body of water;
• a memory unit connected to said processor for storing a measured voltage gradient as a function of time and location;
• a remote processor physically spaced from said buoyant housing with said remote processor comprising a laptop computer or a smart phone;
• and a transmitter/receiver for communication between the processor located on the housing and the remote processor where the frequency selected is from the group consisting of a Wi-Fi frequency (2.4 gigahertz or 5 gigahertz), a Bluetooth™ short range wireless frequency (2400 megahertz to 2483.5 megahertz), or a radio frequency (9 kilohertz to 300 gigahertz) wherein information in the processor on the buoyant housing can be accessed through the remote processor or the processor located within the buoyant housing.
