So are these arches fish? Are all the arches/lines fish? How many fish would you estimate is in this photo?

Thanks

Yes chart speed was on 8, so ill slow it down. The boat was stopped, moving slightly with the current.

look at the bottom d,imaging shot,,,,,,,,,,,,,,,,the arches mach up perfectly with the typical D,I white streaks that a fish would look like,,,,,,,,,,,,,,must a been drifting pretty fast id say,,or the fish were moving quickly,,,,,,,,The di will typically be a bit ahead of the regular sonar chart when on split screen also
