A-scope
A-scope, display on the right of the screen, shows echoes at
each transmission with amplitudes and tone proportional to their
intensities. It is useful for estimating the kind of fish school and bottom

1. Weak reflection (Fish or noise)
2. Strong reflection (Fish)
3. Strong reflection (bottom)
Note : Go to the sounder options menu and check the A-Scope Peak Hold option to hold the echo return
in the A-Scope for a couple of seconds.
Sounder Mode
The Sounder mode is the time advance display mode, echo displayed at each echo arrival. The X axis

Select operating frequency: When acoustic energy travels through the water, the frequency
determines how deep it will travel and also the level of definition you can expect to see after it has
bounced off an object below.
