[CA] [CA11] Help with odd sonar readings

[Chuck - Raymarine - Moderator]

Wade,

The performance shown is indeed quite atypical. It is recommended that a Sonar Reset be commanded for each of the supported fishfinder channels. Should the problem persist, then it would be recommended that a Factory Reset be commanded. Thereafter should the problem persist, and given that the problem persists with either the 200kHz or low power / high frequency CHIRP conical sonar pinging, I believe that there may be an issue with the sonar processing circuity of the Axiom MFD which the transducers have been interfaced to. It would accordingly be recommended that the MFD along with the Y-Cable used to link the two transducers be sent to Raymarine’s Product Repair Center to be bench checked / serviced.
