Shows suspended targets as symbols with target depth information.
Pic. Advance: Allows the sonar picture to advance faster by drawing more than one column of data on
the screen for each column of sounder data received. This is especially helpful when you are using the
sounder in deep water, because the sonar signal takes longer to travel to the water bottom and back to the
transducer.
The 1/1 setting draws one column of information on the screen per sounder return. The 2/1 setting draws
two columns of information on the screen per sounder return, and so on for the 4/1 and 8/1 settings.
