In YouTube there is a presentation on how to make an electric worm getter for fishing. Electrical current will force worms out of the ground and to the surface. The makeshift device seems to work very well in getting worm to the surface. There is a question, however, on its safe use. The device cannot be used with an GFCI. Is this device a safe arrangement? Is the user safe from shock/electrocution? Any words of wisdom would be appreciated. Name of the YouTube presentation is: HOW TO MAKE THE ULTIMATE ELECTRIC WORM GETTER
