Sonar Views
The sonar views available vary depending on the type of
transducer and optional sounder module connected to the
chartplotter. For example, you can view the Split Frequency
view only if you have a dual-frequency transducer connected.
There are four basic styles of sonar views available: a full-
screen view, a split-screen view that combines two or more
views, a split-zoom view, and a split-frequency view that
displays two different frequencies. You can customize the
settings for each view in the screen. For example, if you are
viewing the split-frequency view, you can separately adjust the
gain for each frequency.
Traditional Sonar View
There are several full-screen views available, depending on the
equipment connected.
The full-screen Traditional sonar view show a large image of the
sonar readings from a transducer. The range scale along the
right side of the screen shows the depth of detected objects as
the screen scrolls from the right to the left.

DownVü Sonar View
NOTE:
Not all models support DownVü sonar technology and
transducers.
NOTE:
To receive DownVü scanning sonar, you need a
compatible chartplotter or fishfinder and a compatible
transducer.
DownVü high-frequency sonar provides a clearer picture below
the boat, providing a more detailed representation of structures
the boat is passing over.
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.
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.
