Fishfinder issues with Dragonfly 6

[jlochner]

Took the boat out yesterday, no issues with the GPS however the fishfinder/sonar locks up after short periods of use and display nonsense depths. I checked the transducer to make sure it was in the locked down position which it was. I doesn't make a difference whether I am running on battery or with the engine running.

How do I coordinate shipping the unit back to be tested? What are the chances the failure has to do with the transducer?

Thanks
