The LongLiner is suitable for lines and leaders from 6# test to 60# test (up to 125# test in spectra lines).  A valuable tool for Kayakers as well as trollers in larger watercraft.  LongLiner gives you long leader presentations away from the boat and the control benefits of  landing fish with a short leader!

Some call this "the tackle box downrigger."  

Weight attachment options include two products: Weight Hanger and the Bottom Skipper on this site.
