Using the Cursor on the Echosounder Panel

The cursor is by default not shown on the sounder image.

When you press one of the arrow keys the cursor will be

visible, the depth at the cursor position will be shown, the

information window and the history bar will be activated.

You use the arrow keys to move the cursor in any direction

on the display.

To remove the cursor and cursor elements from the panel, press the ‘X’ key.

Using the cursor to position a waypoint

You can position a waypoint at the cursor position by

pressing the ‘PLOT’ key as described in the Waypoints,

routes and tracks section.

When the key is pressed the waypoint symbol and ID are

positioned at the cursor position.

Viewing sounder history

Whenever the cursor is shown on a sounder panel, the green scroll bar is also shown.

The scroll bar shows the image you are currently viewing in relation to the total

echosounder image history stored.

When the scroll bar is on the far right side it indicates that you are viewing the latest

soundings. If you move the cursor to the left side of the screen the history bar will start

scrolling towards left, and the automatic scrolling as new soundings are received will be

turned off.

To resume echosounder scrolling, move the cursor to the right until the green history bar

reaches the right side of the image, or press the ‘X’ key.

Measuring distance

The cursor can be used to measure the distance between the position of two

observations on the sounder image. It is easier to use the measure function when the

sounder image is paused.

Use the following process to measure a distance:

Move the cursor to the ﬁ rst 1

measuring point

Start the Measure function2

Move the cursor towards the second 3

measuring point

A line will be drawn from the first -

point to the cursor, and the distance

will be listed in the Information

window

You can reset the measurement by pressing the Tick key.

When you press the ‘X’ key the echosounder will resume to normal scrolling.
