Catching more fish from shore requires some preparation. Using a castable fish finder is a great way to figure out what the bottom looks like and if you should stay. iBobber is the lightest portable fish finder and can be cast long distances. Map the bottom contours, locate fish or structure, ledges and holes where the lunkers lurk. You can GPS mark spots, laydowns (trees that have fallen), weed beds, drop-offs and other underwater structure where fish might be laying in wait to ambush baitfish.
