Fish finder help
 

When the fish show up on your fish finder (right side), at this point are fish in front of the kayak?

In my experience, and anybody correct me if I’m wrong, the first image on the right is the most recent image received by the first sonar contact with ground/objects/fish in between in the cone shape. (I’m sure there is easier way of explaining it)
I think, It’s basically first image of the entire cone shape sound that is bounced back and interpreted.

That’s correct

To answer the OPs question the sonar on your fish finder shoots its signal down into the water is a cone shape, usually straight down( wherever the transducer is pointing). Therefore any returns you are seeing on the fishfinder is the signal bouncing back from any object the signal strikes within that cone below the kayak. It is not really possible to tell the direction. The area farthest to the right on your screen is the most recent returned signal.


In my opinion the "fish finder" is not the right name for it. I don't really use it to find the fish. It's more of tool to provide you with additional information, water temperature, structure location, knowing if you are on hard bottom or soft bottom an knowing if there are fish somewhere below in the water column. Fish swim, and they swim fast. By the time you're marking them on your sonar and get a bait down in the water they can be 100 feet away.

1 hour and 55 minutes! Oh my.

This calls for sandwiches and some refreshments.

I need to understand fish finders much better than I do, so I'm going to plow through this. Thanks.
