I am still learning how to read my graph, but as I was kayaking around, these were very common images I would see. Some taller weed stalks with fish suspended on them toward the tops was also a common occurrence. For the fish on the bottom, I have a finesse jig and a ned rig tied on an no luck. Maybe a drop shot would have been good to try?

Any words of wisdom are appreciated.

I found this a few years when i was helping my dad with his chirp setup, has some good 101 info. https://fishncanada.com/how-to-read-a-fishfinder-traditional-chirp-sonar/

I think it's a Manatee!

huummm......ogpogo maybe?

If you think and say they are, they are.

The ones in the top are probably not, however the ones on the bottom look like it. drop shot them. If there was a tree or vertical structure I would say crappie.
