Echogram views
The ME70 supports several different echogram types. Each echogram is shown in a separate view in the ME70 presentation. The tabs at the bottom of the ME70 presentation allows you to choose which channels to open.
Supported echogram types
•  Surface: A Surface echogram is mainly used when you wish to look at the entire water column starting from the sea surface and down to the sea bottom.
•  Bottom: A Bottom echogram is mainly used when you want to examine the echoes from fish close to the sea bottom.
Bottom bar
The bottom bar is located at the bottom of the display presentation and stretches from the left side to the right side. A dedicated tab provides a special view for you to see the screen captures you have made. The product name tab brings you back to normal view. The bottom bar also shows the current colour scale, the transceiver status button and the date and time.

Click once in the view that you wish to change. The view is activated. It is identified with a thick border. Open the Active menu, click Echogram to open the dialog box, and select Echogram Type on the Echogram page.
In each echogram view, you can also select from a number of markers, lines and annotations to enhance the echogram, or to provide additional information. These can be selected on the Lines page in the Echogram dialog box.
