Made in the USA! The Ninja Grass Blade is a small aluminum attachment on your trolling motor that has 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! Ninja Grass Blade for Lowrance Ghost has a little bit smaller cutting surface than the 2.0 to fit the Lowrance Ghost.
