The Erupt Fishing RTD Rod Threading Device features patented technology that threads line through every single guide on your fishing rod in mere seconds! Every fisherman has experienced the frustration of threading their line through the first several guides, only to drop the line and have it fall through every guide and having to start over. Some anglers experience difficulty seeing and handling thin monofilament or braid, making threading their rods a frustrating task. The RTD Rod Threading Device eliminates these issues by threading line through every guide in one easy motion. Simply attach your line to the bobbin with a simple tug into the line catch, and then run the RTD up the length of the rod. The RTD self-centers along the fishing rod to feed the line through each guide, as it is drawn up the rod from reel to tip. This device works perfectly with all rods that have standard sized guides.
