Sonar Fishfinder
When properly connected to a compatible transducer, your chartplotter can be used as a fishfinder.
For more information about which transducer is best for your needs, go to garmin.com/transducers.
Different sonar views can help you view the fish in the area. The sonar views available vary depending on
the type of transducer and sounder module connected to the chartplotter. For example, you can view certain
Panoptix sonar screens only if you have a compatible Panoptix 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.
If you do not see an arrangement of sonar views to suit your needs, you can create a custom combination
screen (Creating a New Combination Page with the ECHOMAP UHD 70/90, page6).
Stopping the Transmission of Sonar Signals
• To disable the active sonar, from the sonar screen, select Menu > Sonar Transmit.
• To disable all sonar transmissions, press , and select Disable All Sonar.
Traditional Sonar View
There are several full-screen views available, depending on the transducer that is connected.
The full-screen Traditional sonar view shows 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.

Split-Frequency Sonar View
In the split-frequency sonar view, the two sides of the screen show a full-view graph of sonar data of different
frequencies.
NOTE: The split-frequency sonar view requires the use of a dual-frequency transducer.
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.
