This high-frequency sonar gives you a clearer picture of what's below your boat, by producing a more detailed representation of objects, structure and fish. DownVü with CHIRP technology takes it one step further, producing an ultra-clear page with even more detail. DownVü scanning sonar is built into our echoMAP combos, and DownVü scanning sonar with CHIRP technology is built into our GPSMAP combos. Learn more about DownVü scanning sonar.
SideVü shows you what is happening to the sides of your boat. An excellent way of finding structures and fish. SideVü with CHIRP technology provides an even more detailed and higher resolution image of what is beneath the surface. SideVü scanning sonar is built into our echoMAP sv combos, and SideVü scanning sonar with CHIRP technology is built into our GPSMAP combos. Learn more about SideVü scanning sonar.
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
