7. FISH FINDER (SOUNDER)
7-4
Bottom zoom display
The bottom zoom display expands the bottom and the fish near the bottom according
to the zoom range selected on [Zoom Range Span] in the [Settings] - [Sounder] menu.
This display helps you find the density of the bottom. A short echo tail normally indi-
cates a soft bottom (sand bottom, etc.). A long echo tail indicates a hard bottom.
