The Foot Plate may to be used with the Eagle MicroGen, Guardian, or Wave Master (discontinued). Two stainless steel plates are mounted on an insulated base and have connecting jacks and a cord to connect to the generator. The Foot Plate is an excellent accessory because it is built to last a lifetime and provides the best way to output the frequencies into the lower part of the body. The Foot Plate comes with a Split Cord. NOTE: If the Foot Plate is going to be used with the Guardian, you must request a Custom Split Cord.
