Fishnder A-Scope mode
The A-Scope mode enables you to view a live (rather than historical)
image of the seabed and sh directly below your vessel.
The standard shnder display shows a historical record of shnder
echoes. If required, you can display a live image of the bottom
structure and the sh directly below the transducer by using the
A-Scope feature. The width of the bottom covered by the A-Scope
is indicated at the bottom of the window. A-Scope provides a more
precise and easier to interpret indication of the target strength.
There are three A-Scope modes, as illustrated in the diagram below:
Enabling the Fishnder A-Scope Mode

The softkey name changes to ADJUST...
2. Select the ADJUST... softkey.
3. With dual frequency screens select FREQ1 or FREQ2 to select
which frequency display you wish to change.
