A friend of mine purchased an A90 to use on his ocean boat, is there a video showing the best settings for all around use? He said that his C80 picks up suspended bait fish and fish much better than his newer A90. im sure the settings are wrong but can't find any videos that explain how to best set it up. any help would be great.
Any idea what ducer was on the C80? Are they installed in roughly the same place? I'm trying to determine if we are comparing apples to apples or apples to oranges.
Regardless, I'd suggest the software update, Sonar reset and run them in "auto" to start.
