Question:
How do fish show up in down imaging? Well it be an arc like 2d? Or do they not show up that way or at all?

Also... when I get to 20 fow the 2d lights up at the bottom. Is that due to thermalcline or no oxygen zone? I see weeds then I see the drop with no weeds then it lights up again but there are no weeds there. Why is that?

Thanks

The water below the thermocline may or may not contain oxygen. In deep clear lakes there is usually moRe than enough foe which the trout are thankful. Sometimes you can see the thermocline on 2d but I doubt you'll see it on DI. I'm notat all sure what you mean when you say it lights up.
