The banana-shaped design of the NO-SNAGG Slip Sinker was developed by legendary angler Ron Lindner. It allows the sinker to glide over heavy cover while giving the fisherman a better feel of the bottom—without tumbling, twisting, or impeding bait action. Extensive field-testing of the NO-SNAGG Slip Sinker in 'unfishable' areas of lakes, rivers, and reservoirs has yielded 95-percent snag-free results! Lindy's sinker innovation enables anglers to fish rocks, brush, weeds, and stump fields like never before. And it works equally well whether Lindy Rigging, Carolina-Rigging, drifting, or trolling.
