Humminbird WIDE Paramount 3D - Manual (Page 25)

The Wide 3D Paramount will help you further differentiate
between fish by assigning either solid, gray or hollow fish
symbols. Solid fish pointing to the right are detected in
the right inside beam, solid fish pointing left are detected
in the left inside beam. Gray fish pointing right are
detected in the middle right beam, gray fish pointing left
are detected in the left middle beam. Hollow fish pointing
to the right are detected in the right outside beam, hollow
fish pointing to the left are detected in the left outside
beam. To help accurately locate fish, Fish ID attaches
fish returns to the bottom at a point which precisely
shows the left-right location of the return. ID+ also
assigns a depth to each fish to help locate fish vertically.
By understanding how the Wide 3D Paramount interprets
and graphically depicts sonar information, the user can
confidently and accurately locate fish, relative to the
location of the boat.
Using the 2D View
When operating in the 2D view, the Wide 3D Paramount operates like most depthsounders.
However, there are several exceptions. The six beam 53 degree transducer allows you to search
for fish with a much wider area of coverage than most depthsounders. Only the two center beams
provide information to draw the bottom depiction. Using a narrower beam provides much more
detailed information. Also, you have the ability to quickly switch back to the 3D view for a better
idea of where targets are located.
Figure H shows a typical view you can expect to see on-
water, when using the 2D view. New sonar information
appears on the right side of the graphic area of the
display and moves to the left as new information is
displayed. The Wide 3D Paramount automatically selects
the appropriate depth range to show the depth of water
beneath the transducer. This range is selected so that the
bottom representation is typically shown about 2/3 down
the display.
The graphic depiction of the bottom provides the user
with an effective tool for understanding the composition of the bottom. The FSTN type display
uses 4 discrete levels of gray to indicate the intensity of the returned sonar signal. The Wide 3D
Paramount can display even the smallest sonar returns with light gray pixels. Larger returns are
displayed with darker shades of gray. If the bottom is hard and smooth, the bottom depiction is
narrow and dense. If the bottom is soft mud or sand, the depiction will be thick and less dense.
This indicates that much of the signal is absorbed by the soft bottom. If the bottom is rocky or
rugged in composition, the depiction is of varying density and textured in appearance.
