The Cannon Downrigger TS Spare Spool, or replacement downrigger cable spool, is capable of supporting either monofilament or any of the popular ”super lines.” The only stainless steel spool in the industry (made of 316 grade stainless steel), the Downrigger TS Spare Spool eliminates the noise vibration and harmonics created when trolling with a steel cable. Compatible with Cannon TS (Tournament Series) models.
