Welcome to the Raymarine Forum Rude,

The Transducer Selection feature does not apply to the Sonar and DownVision features associated with the internal CHIRP (conical) sonar / DownVision sonar circuitry of the ax8 MFDs, eSx8 MFDs, and CP100 CHIRP (conical) / DownVision Sonar Module ... hence the Fishfinder application of your system is not providing a Transducer Selection option. When using the Fishfinder application with a system such as yours, Selection of Sonar will display imaging from the CHIRP (conical) element of the interfaced CHIRP/DownVision transducer and Selection of DownVision will display imaging from the Downvision element of the CHIRP/DownVision transducer. Should a plot be generated, then the system would be determined to be operational. Additionally, should the vessel be located in the water and the water's depth below the transducer be at least 3 feet, then the Depth data item should display a value rather than -.-.
