I've had an Eagle FishMark 500c up front in my boat but added a Lowrance X510C to the rear. It has much better pixel resolution and I'm able to see a lot more with it. I'm still trying to make sure that I know what I'm looking at so help me out if you can.

Are these two pics a ball of baitfish?





Is this a ball of baitfish just above the weed line?



What exactly am I looking at here? I was trolling crankbaits when I took the pic, it's not my lure or anything like that.



Ball of baitfish to the right of some structure and fish?
