I posted a similar image up there and the conclusion was its bait fish. Now I took this picture and I'm wondering if it's something wrong with how my transducer is mounted or this just typically how weeds may look on mega down imaging. I am expecting fully fleshed images of weeds but here I am just seeing what looks like a big smear across the screen with less definable bait fish "dots". Is this weeds, or something else?

Ok thanks I'll just go with that.

This is Lake of the Prairies in Manitoba.

I have a helix mega si+ so the bottom image there is mega down imaging+ chirp. I have seen some amazing structure images, rocks and such, but then I came across this which I assumed was weeds just by the hard return in the center of it and the proximity to the bottom, but then the down imaging is supposed to help me nail down what exactly it is but instead it only confused me. It looks to me like a bunch of little bait fish and the sonar says to me it could be either or. Why can't I see detailed weed images on my down imaging if it is in fact weeds?
