This article was written by Capt. Billy Thomas and discusses the problems with blowback caused by friction when using a lead ball. The Zwing, as a hydrodynamic depressors eliminates these issues. The article reads, “The Zwing (www.zwingdownrigger.com) attaches to the downrigger line and replaces the heavy ball. Its design allows it to “dig” and maintain a constant depth with no blowback, at a wide range of speeds. You can figure on deploying 52 feet of downrigger line to keep a Zwing riding 50 feet deep because the line will hold a 16-degree angle.”
