Detecting Harmful Electricity

Looking for a better way to detect stray electrical currents, and therefore prevent injuring swimmers or damaging underwater metals? Have a look at ESC’s DockTester, a winner of the the 2003 NMMA Innovation Award.
“Before DockTester, onboard electrical problems could only be detected by an impractical, time-consuming visual inspection of every wire and connection. DockTester easily identifies the existence and magnitude of stray electrical currents on vessels and in the surrounding water. The portable in-line tester connects between a boat’s shore power cord and the dock’s AC receptacle.”
