This item is user friendly for various installation options – * Trolling Motor * Side of the Jack Plate * Hole Shot Plate or * Set Back Additional components are required. It is important for us to know this please. This Transducer Shield DOES NOT fit the Garmin GT 36 or GT 56 transducer. NOTE: When the transducer is attached to a Set Back, Hole Shot Plate or the side of a Jack Plate, it will not track the bottom when up on plane because the transducer is out of the water. For bottom reading on plane, a transducer inside the hull will be required.
