Make sure the correct transducer is selected in the DF settings. Mine was still set for my original transducer and caused inconsistent readings . It has to match the properties of the built in unit.
Don't forget the Fortrex transducer is probably a foot to 2 feet deeper in the water than the transducer on the transom.
