Understanding the Graph
It is important to understand that the unit does not display a 3-D representation of the underwater
environment. The unit can display multiple things at the same time, but cannot determine where the return
originated – only when it was received.
Examples 1 and 2 provide a look at the underwater world from a top view, and illustrate how these
views would be displayed on the graph. On both graphs it appears the fi sh and tree are side by side as
shown in Example 1. However, when we look at Example 2, we see that the fi sh can be several feet from the
tree. It is important to remember that the Fishfi nder cannot determine where in the coverage area the tree or
fi sh are, only that the returns were received at the indicated depths in the same time frame.

Understanding the Graph
Remember that the Fishfi nder displays a 2-D picture of
the underwater environment. The fi sh and tree could be
located anywhere in the coverage area at that time.
