A-scope display (display only)
The A-scope display, available in all modes, shows echoes at each transmission
with amplitudes and tone proportional to their intensities, on the right 1/10 of the
screen. It is useful for estimating fish species and bottom composition. To turn on
the A-scope display, press the DISPLAY MODE soft key, select display mode
desired, then press the A-SCPE soft key to show "ON" on its label. For modes
other than SINGLE FREQ the screen must be split horizontally to show the
A-scope display.
