Check the Owner's Manual.* See what the*discrimination is.* This is the distance between two objects.* If it's six inches, you'll see objects that are six inches apart or more.* Also fish that are six inches off the bottom.* You should be able to see fish on the bottom, if they're off the bottom more than the discrinination figure.* I use to have the Lowrance X-16 paper graph.* The discrimination was down to one inch!*
