A stepped hull contains a notch (or step) that runs crosswise across the boat hull and helps the boat generate more lift at higher speeds. If transducer is mounted after the notch, the notch creates cavitation and will interfere with sonar returns. For this reason, the transducer should be mounted in front of the notch, closer to the front of the boat.
A cored hull refers to a hull with a void between the 2 layers of hull material. Sonar cannot transmit through that void.
The deadrise angle is the angle between the horizontal line of the water and your boat's hull
