[CA] [CA11] i50 with old tranducer

[Chuck - Raymarine - Moderator]

Larry,

It would have been recommended that the pod be opened and that the test transducer have been connected to the instrument and then suspended over the side of the hull ... that now appears to be water under the bridge. The only other way to test the instrument would be to interface sonar test equipment (ex. EDI DSTS-4A, etc.) to the i50 instrument. Alternatively, the instrument may be sent to Raymarine’s Product Repair Center to be bench checked / serviced.
