no depth output on my unit
« on: August 09, 2018, 08:13:05 PM »
I just bought a unit of second hand hummingbird 1197c, I tested it with a pail of water indoor, but the unit is not giving any depth readings or sonar image (even erratic signal). I have tried all settings in the unit but no luck, any one can help to advice what else I can check?

Have you tried Restore Defaults under the Setup  ...??

Testing in a bucket may not give definitive results  ... Can you test on the water  ...??
