The telephone method works best in moving current with rock bottoms. most ponds the bottoms have too much mud in it to get a good charge. best in rivers{but like mentition in eariler post its not legal on public waters, i.e. confiscate boat, gear, truck, an mainly you. } This method also really only works on skined fish like catfish an such so not really good for a LMB/BG pond. It will sure get them big old cats to flopping to the surface \:\) {ya know from what ive heard that is ;\) }
