The triangular foil-type design of the Hot Spot Agitator Flasher enables it to glide through the water with far less drag than other styles. That means smooth, stable trolling runs with little chance of tangling on turns, plus maximum flash and vibration at all speeds. The Agitator's patented easy-roll design includes ball bearing swivels with welded rings and brass eyelets, for the strength and performance required for heavy-duty trolling, day in and day out.
