TCK73 - I don't know what kind of fishfinder that is but WOW great screen shots. Not a lowrance or Hummingbird unit. What type is it.
I have a Lowrance and gets pretty good pictures.
For advice, look for the long noodles. Whites, Stripers and Hybrids look like noodles on the screen. The noodles which connect to the bottom are more likely to stay in one place when jigging then suspended ones.
Well, it is a Humminbird Onix.
As for the noodles you speak of, that all depends on frequency, chart speed and boat speed. I can make it look like noodles, but I prefer having target separation. My kid and I stayed on that school for nearly three hours, caught over 90 whites and 40-50 small Stripers. There were also some legal Stripers right on bottom we caught, but it was hard to set the jig past all the other fish before it reached bottom.
