This pic appears to have tons of fish suspended throughout the water column, however, the sonar returns and the white specks on the DI all seem to indicate they are tiny. What size and species may they be based on their sonar returns and position in the water column? Also what is causing all of the returns coming from 30-40 fow on the 2D sonar? Thermocline?


This shot I am passing under a bridge which has a total of 4 columns on each side. The SI and DI do a good job of showing that. I passed close by to the columns on my left which I assumed is why the DI caught them too. It looks like there are lots of fish and even a couple of large bait balls or schools of something. Any ideas on what I am looking at? Also same returns at 30 fow and down.


I'm drifting here with my chart speed set on 1 mph I believe. These kind of slow moving shots still dont make much sense to me. Is the returns DI is picking up a piece of structure or what? And again the 30 fow+ readings on 2d sonar.
