Dead Zone Fish... We rarely see fish on drop-offs because the closest “bottom” to the transducer is the drop-off so the fish are not seen. All sonar displays is echo strength of the target and the distance the target is from the transducer. The first example has the fish a farther distance from the transducer than the bottom so the fish echo is added to the “bottom “echo and not seen. The “bottom” under the transducer is 25 ft, fish at 23 ft, and the drop off “bottom” is 20 ft. Now visualize what the sonar will show you. The picture is my rough drawing so it is not to scale; it is just to get you thinking.
The second example shows a fish in the dead zone.
I have only captured one recording like this so the conditions have to be perfect.
