The Precision Sonar Ninja Grass Blade is a small aluminum attachment for your trolling motor that provides a cutting surface. Every time the trolling motor prop picks up any grass it will run the grass across the cutting surface and chop it into small shreds to make sure your prop keeps spinning even in the thicket grass.Note: 2.0 fits most popular trolling motors EXCEPT the Lowrance Ghost.FeaturesAluminum trolling motor attachmentCuts through the thickest grassKeeps your prop spinning
