Conguring Advanced Data Fields
The top-left corner of the screen contains congurable data elds
for the Sonar Pages. You can view basic or advanced data for these
data elds. By default, the Basic conguration shows the depth,
water temperature, and speed (depending on the Graph tab settings
and the type of transducer or sensors attached). The Advanced
conguration shows a larger, congurable data eld with a white
background. The Advanced Data Setup Menu allows you to specify
the type of data shown and either a (small) or Wide
(larger) size format for each data eld.
