RKW68,

Given the actions taken, the reported issue would then indicate either a fault within the MFD's internal sonar circuitry or within the transducer itself. It is recommended that a Certified Raymarine Installer be contacted to test the transducer with an EDI or Gemeco transducer tester and to test the MFD with another compatible transducers. Alternatively, the MFD may be sent to Raymarine’s Product Repair Center to be bench checked / serviced.
