The Tracker Bar has quickly become the most productive spreader bar in the Northeast. We have added a transparent plexiglass keel under the lead bar bird that causes the bar to track up to 30' feet outwards from its normal tracking line (depending on distance from boat, speed, wind and sea conditions). This allows this bar to run in clean water and attract more bites! As with all Sterling products, it is built with high quality components, is TESTED and PROVEN to catch all pelagic fish. "Sterling Tackle builds the most productive spreader bars on the planet", Mark DeBlasio- Blue Runner Sportfishing The Tracker Bar can be pulled straight from rod tip or outriggers. Whether you fish it from your outriggers or rod tips, this innovative bar allows you to increase your overall spread width by as much as 60'. Available in Port and Starboard versions, or you can buy a pair, which will have one of each. ​Tip: You can double rig your long rigger with two clips to maximize the effect.
