B&G Zeus2 Glass Helm CPU - Manual (Page 69)

Zooming an Echosounder image
You zoom an Echosounder image by:
• Touch operation: pinching or spreading on the screen, or by using the panel zoom icons
• ZC1 operation: using the IN/OUT keys or the rotary knob
• Keyboard operation: using the +/- keys
Zoom level is shown on the upper left side of the panel.
When zooming in, the sea floor will be kept near the bottom of the screen, irrespective of
whether it is in auto-range or manual range.
If the range is set considerably less than the actual depth, the unit will not be able to find the
bottom when zooming.
If the cursor is active, the unit will zoom in where the cursor is pointed.
Zoom bar
The zoom bar will be displayed when you zoom the echosounder image.
Drag the zoom bar vertically to view different parts of the water column.
Using the cursor on the echosounder panel
The cursor can be used to measure a distance to a target, to mark a position, and to select
targets.
The cursor is by default not shown on the echosounder image.
When you tap the screen the depth at the cursor position will be shown, the information
window and the history bar will be activated.
To remove the cursor and cursor elements from the panel, select Clear cursor menu option.
GoTo cursor
You start navigating to a selected position on the image by positioning the cursor on the
panel, then using the go to cursor option in the menu.
The Cursor assist function
When using a touch screen, the cursor assist function allows for fine tuning and precision
placement of the cursor without covering details with your finger.
Press and hold your finger on the screen to switch the cursor symbol to a selection circle,
appearing above your finger.
Without removing your finger from the screen, drag the selection circle over the desired item
to display item information.
When you remove your finger from the screen the cursor reverts to normal cursor operation.
Measuring distance
The cursor can be used to measure the distance between the position of two observations
on the image.
It is easier to use the measuring function when the image is paused.
1. Position the cursor on the point from where you want to measure the distance
2. Start the measuring function from the menu
3. Position the cursor on the second measuring point
- A line will be drawn between the measuring points, and the distance will be listed in
the Information window
4. Continue selecting new measuring points if required
You can use the menu to re-position the start point and the end point as long as the
measuring function is active.
When you select Finish measuring the image will resume to normal scrolling.
