• I was zapped by something, possibly one of these, while wading in knee deep water on a sand bar in shell cove, Sydney Harbour one summer. It was a good jolt! Having grown up on the land I know what the thump of a few thou volts in an electric fence feels like. While searching for this info I also found a sailboarding blog which described receiving an electric shock from stepping on something in the water in rose bay.
