The Ultimate Yamaha PWC lanyard has 4 keys to fit ALL brands. A stainless steel key ring is also included for hooking up to Sea Doo D.E.S.S. devices or a car key. We call it “Ultimate Lanyard” because it has a comfortable floating detachable wrist band, floating vest lanyard and high pitch pea-less whistle for emergencies. A swivel snap hook keeps the cord from tangling. No accessories to buy for this lanyard!
