Blue vertical lines on dragonfly 5 pro

Mark,

The reported marks may be resulting from electronic noise. It is recommended that the problem be duplicated when next out on the water. At that time, it is then recommended that the engine and all other electronics switched OFF to determine whether the problem persists. If so, then it would be recommended that the display be sent to Raymarine’s Product Repair Center to be bench checked / serviced. Should the reported streaking go away, then it is recommended that the transducer's cable routing be examined to ensure that it has not been routed with other cables.
