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.
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.

Adjusting the Level of Detail

You can control the level of detail and noise shown on the sonar
screen either by adjusting the gain for traditional transducers, or
by adjusting the brightness for DownVü and SideVü/DownVü
transducers.
If you want to see the highest intensity signal returns on the
screen, you can lower the gain or brightness to remove lower
intensity returns and noise. If you want to see all return
information, you can increase the gain or brightness to see
more information on the screen. This also increases noise, and
can make it more difficult to recognize actual returns.

Select an option:
• To increase or decrease the gain or brightness manually,
