A-Scope

The PI54 provides an A-Scope function. This presentation

provides the echo from the latest ping only. The strength of the

returned signal from various depths in the water column are

indicated by the horizontal deflections from the Y-axis. T his

presentation is very useful if you wish to search for single fish,

as those echoes are hard to see on the regular echogram. Also,

various echoes are.

To enable this function, press the ENT button to open the Echo

quick menu, and select Activat e A-Scope. To disable it, select

Hide A-Scope on the same menu.
