Installation close to echo sounder transducer(s)
It is common for vessels to have both echo sounders and sonars on board. The respective transducers are then installed close to each other under the hull.

For most installations we recommend that the echo sounder transducers are placed in front of the sonar installation trunk. When the sonar transducer is lowered, the transducer shaft and the transducer itself cause disturbances in the water flow. These disturbances may significantly reduce the echo sounder performance if the echo sounder transducers are placed aft of the sonar.
