Split screen options
Zoom
The Zoom mode presents a magnified view of
the sounder image on the left side of the panel.
By default the zoom level is set to 2x. You can
select up to 8x zoom from the drop-down
menu.
The range zoom bars on the right side of the
display shows the range that is magnified. If you
increase the zooming factor the range will be
reduced. You will see this as reduced distance
between the zoom bars.
Bottom lock
The bottom lock mode is useful when you want
to view echoes close to the bottom.
In this mode the left side of the panel shows
an image where the bottom is flattened. The
range scale is changed to measure from the
seabed (0) and upwards. The bottom and the
zero line will always be shown on the left image,
independent on range scale.
The scaling factor for the image on the left side
of the panel is adjusted as described for the
Zoom option.
Echo frequency
The Zeus Touch 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
Noise rejection
Signal interference from bilge pumps, engine vibration and air bubbles can clutter the image.
The noise rejection option filters the signal interference and reduces the on-screen clutter..
The scroll speed
You can select the scrolling speed of the echosounder image on the screen. A high scroll
speed will update the image fast, while a low scroll speed will present a longer history.
Zooming
You can use the IN / OUT keys to select zooming level on the Echosounder
image.
Zoom level is shown on the upper left side of the echosounder the panel.
When zooming in, the sea floor will be kept near to 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.
