Acme K.O. Wobbler Spoons excite fish by sight and sound! Gamefish are sensitive to the vibrations created by baitfish on the move. K.O. Wobblers mimic this sound with their precision engineered "Sonic Flipper Tail". Once they are drawn by the sound, gamefish are excited into striking by the K.O.'s flashing tail and seductive side-to-side wobble. It's an offer they can't refuse.
