Intermittent depth readout
I have B&G instrumentation on my 40' sailboat, and I've been struggling with my depth readout. When I turn on my instruments, it can take a long time for a depth readout to appear, and is just dashes in the meantime. It has always shown up eventually, perhaps 10 or 15 minutes max wait time. It will occasionally disappear when in use, but that is uncommon.
Anyone have any ideas on a cause or solution?
