First time with electronics, everything set on DEFAULT, just curious what you guys think I'm looking at...(sorry for the iPhone pics, still working out how to take pics on the unit, etc)

Not too bad. All of those things are fish, the half arch ones look that way because of the angle of your transducer or the amount of trim you had on your boat.


The long lines are fish sitting below you, since you are barely moving they look like long lines because your sonar keeps pinging back their return over & over.
