Note:
Setting a custom range puts the sonar in manual mode. If the bottom is well beyond
the lower range set, you may lose digital depth.
Echosounder frequency
The Zeus
2
unit supports several transducer frequencies. Available frequencies depend on the
transducer model that is connected.
You can view two frequencies at the same time by selecting dual Echosounder panels from
the
Home
page.
Color and gain settings
Gain and Color control images are located in the left side of the Echosounder panel. You
activate the control by tapping the image. Active control expands and displays its name in
full. You can then adjust the value 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 are shown on the image. However, a higher
gain setting may introduce more background clutter on the image. If the gain is set too low,
weak echoes might not be displayed.
Auto gain
The Auto gain option keeps the sensitivity at a level that works well under most conditions.
With the gain in auto mode, you can set a positive or negative offset that gets applied to the
auto gain.
Color
Strong and weak echo signals have different colors to indicate the different signal strengths.
The colors used depend on which palette you select.
The more you increase the Color setting, the more echoes is displayed in the color at the
strong return end of the scale.
Pausing the Echosounder
You can pause the Echosounder, allowing you to examine the Echosounder echoes.
This function is useful when you need to position a waypoint exactly on the Echosounder
panel, and if you are using the cursor to measure a distance between 2 elements on the
image.
Advanced Echosounder options
The Advanced option is only available when the cursor is not active.
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.
TVG
The TVG (Time Variable Gain) option compensates for distance to the object, making echoes
from equal sized objects appear with the same size on the echosounder image.
Scroll speed
You can select the scrolling speed of the Echosounder image on the screen. A high scroll
speed updates the image fast, while a low scroll speed presents a longer history.
Ú
Note:
In certain conditions it may be necessary to adjust the scroll speed to get a more
useful image. Such as adjusting the image to a faster speed when vertically fishing without
moving.
