The Wave Wings provide consistent PEMF on either side of the loop to enhance overall wellness. The Wave Wings are great for livestock or bigger animals because they can address a larger area at once. For Example, use the Wave Wings for a full body pig session or the back end of the horse for improved health! The Wave Wings use a patented design to ensure the entire animals body gets a PEMF signal without creating hot spots. The Wave Wings are available in Large (18 inch diameter) and X-Large (24 inch diameter). Both the Large and X-Large Wave Wings come with a 12 ft lead.
