Bottom expansion

The PI32 provides a Bottom expansion function. When enabled

the vertical area close to the seabed is expanded. T he resulting

presentation will not show the depth variations, as the bottom

will appear flat. However, echoes close to the bottom will be

enhanced. Note that the depth range in this presentation will be

“upside down”, as the seabed is defined as level “0”.

To enable this function, press the MENU button, and select

Bottom expansion on the Echo menu. To disable it, select

Echo display on the same menu. The vertical size of the

expansion window is controlled by the Expansion window

parameter in the Presentation setup.PresstheENT button to

access this setup page.

A-Scope

The PI32 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. This

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

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

the presentation will give an indication on how strong the

various echoes are.

To enable this function, press the MENU button, and select

Turn A-Scope on on the Echo menu. To disable it, select Turn

A-Scope off on the same menu.
