The echoes inside the zoomed area will always be shown in the Zoom information pane.

| B | Zoom rectangle used to define the size of the zoomed area |
In this screen capture, the zoomed area rectangle is positioned close to the Zoom information pane. You can however place the pane and the zoomed area independently anywhere you like inside the active view.
Before you open an information pane, you must first click in an echogram view to make it "active". By doing this you select the channel. In most cases, the data in the information pane is only valid for the selected channel. In this context, the term channel is used as a common term to identify the combination of transceiver, transducer and operating frequency.
You can easily change the physical size and shape of each information pane. Click in its lower right corner, and drag to a new size. To reset the information pane to its default size, select the Reset size button in its top right corner.
The Transparency function allows you to adjust how much you are able to see "through" the information panes you have opened. You can adjust the setting from 0% (no transparency) to 90% (almost full transparency) in steps of 10%.
Details
Area Pinned to Vessel
Use Area Pinned To Vessel to control the behaviour of the zoom function. When the rectangular zoomed area is established, it can either follow the echoes while it moves towards the left, or it can
stay put.
| • | When Area Pinned To Vessel is active, the zoomed area will be permanently positioned on the echoes. The echoes shift through the area, and therefore also shift through the Zoom information pane. |
| • | When Area Pinned To Vessel is switched off, the zoomed area will "follow" the echo data from right towards left. |
Close
Select this button to close the information pane. The pane closes immediately. If you wish to reopen it, simply click the button on the top bar one more time.
Reset Size
You may have manually changed the physical size of the information pane. To reset the information pane to its default size, select the Reset size button in its top right corner.
