Sonar display. By default, the Basic display shows Depth , Water
Temperature , and Speed (depending on the Graph tab settings and
type of transducer/sensors attached). The
Configure Advanced

data fields that appear. The data field setup screen shows a larger,
configurable data field with a white background. The setup screen
allows you to select the type of data displayed and either a Narrow

Wide
(large) size format for each data field.
