Can the depth reading of the classic sonar of the RV 220 transducer pair be increased by connecting a CP470 module?
Welcome back to the Raymarine Forum ReelAttitudeBDA,

Q. The maximum depth supported by the high CHIRP (conical) sonar cannot increased by adding a CP470 alone to the system. Additionally, the CP470 would need to be mated to one of the compatible CHIRP transducers or transducer pairs found here.
