[CA] [CA11] Help with odd sonar readings

[Chuck - Raymarine - Moderator]

Wade,

I thought that you had previously indicated that the B60 (50kHz/200kHz Channels) had previously not functioned correctly. That said, the Axiom MFDs feature two sets of fishfinder processing circuitry (one for processing signal from the RV transducer and the second for processing signal from the 50kHz/200kHz transducer). In single MFD systems, the only way to determine whether the fault is rooted in the transducer or the MFD's RV processing circuitry would be to test it with another RV transducer which known to be operation. However, as you have tested the RV transducer with another Axiom RV MFD and found that the problem persists, I would concur that the RV transducer has suffered a failure and should be accordingly be sent to Raymarine’s Product Repair Center to be bench checked / serviced.
