Using the Sonar Page
GPSMAP 585 has an built-in sonar module which allows you to
simply plug in the optional transducer to make GPSMAP 585 a
powerful shnder/asher. “Sonar Turned Off Please Check the
Transducer Connection” message appears on the Sonar page if the
transducer is not properly attached..
The middle of the page contains a right-to-left scrolling sonar image
of the water beneath your boat. Items appear as they pass under the
transducer. The adjustable scale displays the depth of the water. The
information in the upper-left corner allows you to adjust the scale
and displays the water temperature.
