Anytime electricity is near a body of water like a pool, spa, marina, dock or flooded basement, there is the potential for a tragedy in the form of electrocution. A device that detects electricity in water can prevent such tragedies. Our Shock-Guard™ 24/7 system monitors the water and detects electricity in the water and then sounds an alarm warning of the lurking danger and trips the GFI shutting off power to the system.
