Remember pure water insulates electricity it the TDS that shocks you!
A GFCI outlet or an extension cord protected by a GFCI device, properly installed, provides the same circuit protection as a GFCI circuit breaker, according to my electrician friends. The GFCI circuit breakers do protect the entire circuit of outlets coming off that breaker, whereas a GFCI outlet only protects that individual outlet and others "downstream" on that branch of the circuit.
The basic electronics that measure and trip when the amount of electricity return becomes "unbalanced" (a simplified explanation of how GFCI works) are identical in the outlet and circuit breaker.
The BEST protection is to simply unplug everything!!!
