Monitoring the numerical information in a depth layer
The Numerical information field is the best tool for controlling your depth layers. All layers are listed, even those that may be located outside your current echogram presentation. The different layers can easily be activated by clicking the list of numerical data.
Context

Once you create your own layer, all calculated values from this layer are displayed in the Numerical information field. When the layer is selected (“activated”) in the Numerical information field (layer data shown with red text) or in echogram, all data shown by the relevant information fields are calculated values from the echo data within the selected layer.
When a layer is established, it is drawn with two horizontal lines in the echograms. The lines identify the upper and lower depth settings. If you have only one layer, it will always be "active", and shown with red lines. If you have more than two layers, the "active" layer is shown with red lines, while the others are shown with black lines.
By default, a background layer collects all the data from the range chosen on the Main menu. Unless you specify your own layer(s), all data presented by the numerical information field are calculated based on the background layer. This information can be more specific and accurate if you choose to specify layers in the water column.
Procedure
1 Click in any echogram view to make it active.
The information provided will only be valid for the selected channel.The active echogram view is identified with a thicker border.
2 Open the Numerical information field. Click on the grey border and drag I to the left/right to open or minimize/maximize the field. Configure Window on the shortcut menu can also be used to open the information field.
The information from the current "active" layer is shown with red text. The information in the Numerical information field is organized in collapsible lists. Each list can be opened or closed using the small triangle on the left side.
3 Select a different layer.
This is not relevant if you have only one layer, because it will always be "active". If you have two or more layers, there are two ways to do this:
a Click between the two layer indicator lines in the echogram.
The line colours change to red.
b Select the relevant layer in the Numerical information field.
The colour of the layer data changes to red.
4 Investigate the information provided in the Numerical information field.
