Using the A-Scope

The scrolling bottom display provides a historical record of sonar echoes. A-Scope displays a real-time image of the bottom structure and fish directly below the transducer, alongside the scrolling bottom display. At the lower end of the window, A-Scope also displays the patented Bottom Coverage width indication.

To display the A-Scope image:

1.From the top-level Functionbar menu, click A-Scope.

2.Click A-Scope Mode. A drop-down menu appears.

3.From the drop-down menu, select one of the three modes for A-Scope:

ØMode 1 – the A-Scope image is angled outward as the signal width (indicated with dotted lines) increases with depth.

ØMode 2 – the image expands to take up the entire A-Scope window, providing greater resolution.

ØMode 3 – the left-hand side of the image displayed in Mode 2 expands to the entire A-Scope window.

This mode provides the greatest resolution.

4.Click the A-Scope: ON/OFF to toggle the A-Scope on. The display is split vertically, with the A-Scope image in the right hand window and the scrolling bottom image in the left hand window.

Note: If the Bottom Lock or Zoom image is displayed, selecting A-Scope automatically switches off Bottom Lock or Zoom. If you have split frequency selected, the A-Scope image is displayed in both frequency windows.

To remove the A-Scope image:

1.Click A-Scope.

2.Click A-Scope: ON/OFF to toggle A-Scope off.

3.Click ENTER, CLEAR, or BACK to return to the top-level Functionbar menu.
