Saving waypoints
Enter a short description of your concept here (optional).
You can save a waypoint at a selected position by tapping the panel, then selecting the new
waypoint option in the menu.
• If your unit has a
MARK
key, you can press this key to immediately save a waypoint. If the
cursor is active the waypoint will be saved at cursor position. If the cursor is not active the
waypoint will be saved at your vessel's position.
Viewing sounder history
You can view echosounder history by tapping the panel, and then panning the echosounder
image.
Whenever the cursor is shown on a sounder panel, the scroll bar is shown at the bottom of
the panel. The scroll bar shows the image you are currently viewing in relation to the total
echosounder image history stored.
If the scroll bar is on the far right side, it indicates that you are viewing the latest soundings. If
you position 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 normal scrolling, select
Clear cursor
or press the
X
key.
Setting up the Echosounder image
Enter a short description of your concept here (optional).
The range
The range setting determines the water depth that is visible on the screen.
Auto range
If you select Auto, the system will automatically display the whole range from the water
surface to the bottom.
Preset range levels
You can select between several preset range levels.
Custom range
This option allows you to manually set both upper and lower range limits.
The echosounder panel can be setup as a single view, or with split view where the left and
the right side presents different images.
Echo frequency
The NSS evo2 unit supports several transducer frequencies. Available frequencies depend on
sounder module and which transducer model is connected.
You can view two frequencies at the same time by setting up a dual echosounder.
Color and gain settings
Gain and Color control images are located in the left side of the echosounder panel. You
select between the control images by tapping the image or by pressing the rotary knob.
Active control will expand and display its name in full. You can then adjust the value by
turning the rotary knob or by using the slide bar.
You can also adjust the image settings from the echosounder menu.
Gain
The gain controls the sensitivity of the echosounder.
The more you increase the gain, the more details will be shown on the image. However, a
higher gain setting may introduce more background clutter on the image. Conversely, if the
gain is set too low weak echoes may not be displayed.
