While this device may be useful in alerting marinas and boat owners to faults, it should not be used as a "it's safe to swim here" monitor. As I noted in the article, electrical faults occur in the blink of an eye, rather than gradually. If you are in the current path when the fault occurs, the monitor will do you no good. Don't swim in marinas.
Some marinas are installing GFI's on pedestals, and while the effort has good intentions, they have been the source of much frustration as these devices can trip at anywhere between 5 and 30 mA depending upon what's installed. At the lower end of the scale nuisance trips are very common. The ELCI is set at 30 mA, if it's tripping, you know you have a problem.
