Is there anyone else that you know who has a non-DI model Humminbird unit that would let you cross-test with them? This would show where the problem is: unit or boat.
There is another unit running at the console. The two units are not connected I'll be at a tourney this weekend. Hopefully I can find another boat to test with.
