A-Scope

Displays a vertical flasher along the right side of the screen that shows instantaneously the range to targets along a scale.

Depth Line

Shows a quick-reference depth line.

Edge

Highlights the strongest signal from the bottom to help define the hardness or softness of the signal.

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.
