Launched my new (2000) boat today. Key West 2220 Cc. I'm in heaven. But I spent four hours trying to get the chart plotter/sounder to register depth. Just won't do it. Went through the manual (Japanese to English translation) 8 times! Tried everything.<br />Can anyone familiar with this unit give me a hand. I just want to know how may feet are under my boat. Tried everything from auto to manual to more gain less gain, blah blah blah. very frustrating.
