Life-threatening electricity can enter the water of pools, spas, marinas or around a dock from many different sources without anybody knowing that it’s there… a lurking invisible and silent killer.  Our Shock-Guard™ 24/7 system prevents loss of life from electrocution or electric shock drowning by monitoring the water 24/7 and sounding an alarm, even when a small amount of electricity is detected.  Shock-Guard™ 24/7 also instantly trips a GFI circuit, shutting down the power to the pool system.  The system also protects boats from marine corrosion, especially in salt water marinas and docks.  Shock-Guard™ 24/7 provides a much safer swimming and boating environment and “Peace of Mind” for everyone!
