Traditional transducers emit a conical beam. The DownVü
scanning sonar technology emits a narrow beam, similar to the
shape of the beam in a copying machine. This beam provides a
clearer, picture-like image of what is beneath the boat.
SideVü Sonar View
NOTE: Not all models support SideVü sonar and scanning
transducers.
NOTE: To receive SideVü scanning sonar, you need a
compatible chartplotter, a compatible sounder module, and a
compatible transducer.
SideVü scanning sonar technology shows you a picture of what
lies to the sides of the boat. You can use this as a search tool to
find structures and fish.

SideVü/DownVü Scanning Technology
Instead of a more common conical beam, the SideVü/DownVü
transducer uses a flat beam to scan the water and ground to the
sides of your boat.
Split-Zoom Sonar View
The split-zoom sonar view shows a full-view graph of sonar
readings, and a magnified portion of that graph, on the same
screen.
Split-Frequency Sonar View
In the split-frequency sonar view, one side of the screen shows
a full-view graph of high frequency sonar data, and the other
side of the screen shows a full-view graph of lower frequency
sonar data.
NOTE: The split-frequency sonar view requires the use of a
dual-frequency transducer.
Panoptix ™ Sonar Views
NOTE: Not all models support Panoptix transducers.
To receive Panoptix sonar, you need a compatible chartplotter
and a compatible transducer.
ThePanoptix sonar views allow you to see all around the boat in
real time. You can also see your bait being cast into the water
and bait schools in front of or below your boat.
The LiveVü sonar views provide you a view of the live
movement either in front of or below your boat. The screen
updates very quickly, producing sonar views that look more like
live video.
The RealVü 3D sonar views provide three-dimensional views of
either what is in front of or below your boat. The screen updates
with each sweep of the transducer.
To see all five Panoptix sonar views, you need one transducer
to show the down views and a second transducer to show the
forward views.
To access the Panoptix sonar views, select Sonar, and select a
view.
LiveVü Down Sonar View
This sonar view shows a two-dimensional view of what is below
the boat and can be used to see a bait ball and fish.
