Sonar Alarm Settings
NOTE: Some settings require external accessories.
Select Settings > Alarms > Sonar.
Shallow Water: Sets an alarm to sound when the depth is less
than the specified value.
Deep Water: Sets an alarm to sound when the depth is greater
than the specified value.
Water Temp.: Sets an alarm to sound when the transducer
reports a temperature that is 2°F (1.1°C) above or below the
specified temperature.
Contour: Sets an alarm to sound when the transducer detects a
suspended target within the specified depth from the surface
of the water and from the bottom.
Fish Alarm: Sets an alarm to sound when the transducer
detects a suspended target within the specified depth range
and the specified color range.
Advanced Sonar Settings
From a sonar view, select Menu > Sonar Setup > Advanced.
Transmit: Stops the transducer from transmitting.
Shift: Allows you to set the depth range on which the sonar is
focused. This allows you to zoom in a higher resolution in the
focused depth.
When using shift, bottom tracking may not work effectively,
because the sonar looks for data within the depth range of
the focused area, which may not include the bottom. Using
shift also can impact the scroll speed, because data outside
the depth range of the focused area is not processed, which
reduces the time required to receive and display the data.
You can zoom in to the focused area, which enables you to
evaluate target returns more closely at a higher resolution
than just zooming alone.
Echo Stretch: Adjusts the size of the echoes on the screen to
make it easier to see separate returns on the screen.
When targets are difficult to see, echo stretch makes the
target returns more pronounced and easier to see on the
screen. If the echo stretch value is too high, the targets blend
together, and if the value is too low, the targets might be
small and difficult to see.
You can use echo stretch and filter width together to obtain
the preferable resolution and noise reduction. With echo
stretch and filter width set to low, the display has the highest
resolution, but is the most susceptible to noise. With echo
stretch set to high and filter width set to low, the display has a
lower resolution, but has wider targets. With echo stretch and
filter width set to high, the display has the lowest resolution,
but is the least susceptible to noise. It is not recommended to
set echo stretch to low and filter width to high.
Bottom Track: Sets the frequency used for determining depth.
The bottom tracking control allows you to select the specific
channel that is used to track the bottom. For example, you
can set the bottom tracking for the low frequency for deep
water operation.
Temp. Source: Sets the channel for the water temperature log
when more than one water-temperature sensor or
temperature-capable transducer is connected.
Transducer Installation Settings
From a sonar view, select Menu > Sonar Setup > Installation.
Transmit Rate: Sets the length of time between sonar pings.
Increasing the transmit rate increases the scroll speed, but it
may also increase self-interference.
Reducing the transmit rate increases the spacing between
transmit pulses and can resolve self-interference.
20
Transmit Power: Reduces transducer ringing near the surface.
A lower transmit power value reduces transducer ringing, but
can also reduce the strength of the returns.
reductions in power will reduce target
return strength
Filter Width: Defines the edges of the target. A shorter filter
defines the edges of the targets but may allow more noise. A
longer filter creates softer target edges and may also reduce
noise.
Transducer Diagnostics: Shows details about the transducer.
Flip Left/Right: Changes the SideVü view orientation from left
to right.
Install Depth: Sets the depth below the water line where the
Panoptix transducer is mounted. Entering the actual depth
the transducer is mounted will result in a more accurate
visual presentation of what is in the water.
Flipped: Sets the orientation of the Panoptix sonar view when
the down view transducer is installed with the cables pointing
toward the port side of the boat.
Beam Width: Sets the width of the Panoptix transducer beam.
Narrow beam widths are better for high-speed operation and
rough sea conditions. They also can improve bottom
definition and thermocline definition.
Wider beam widths generate larger arches for fish target
returns, making them ideal for locating fish. Wider beam
widths perform better in deep water. They can generate more
surface noise and reduce bottom signal continuity during
rough sea conditions.
Use AHRS: Enables the internal attitude heading and reference
system (AHRS) sensors to detect the installation angle of the
Panoptix transducer automatically. When this setting is
turned off, you can enter the specific installation angle for the
transducer using the Pitch Angle setting. Many forward view
transducers are installed at a 45-degree angle and down
view transducers are installed at a zero-degree angle.
Sonar Recordings
Recording the Sonar Display
NOTE: Not all models support sonar recording.
1
Insert a memory card into the card slot.
2
From a sonar view, select Menu > Sonar Setup > Sonar
Recording > Record Sonar.
15 minutes of sonar recording uses approximately 200 MB of
space of the inserted memory card. You can record sonar
until the card reaches capacity.
Stopping the Sonar Recording
Before you can stop recording sonar, you must begin
recording it (Recording the Sonar Display).
From a sonar view, select Menu > Sonar Setup > Sonar
Recording > Stop Recording.
Deleting a Sonar Recording
1
Insert a memory card into the card slot.
2
From a sonar view, select Menu > Sonar Setup > Sonar
Recordings > View Recordings.
3
Select a recording.
4
Select Delete.
Playing Sonar Recordings
Before you can play back the sonar recordings, you must
download and install the HomePort
sonar data onto a memory card.
1
Remove the memory card from the device.
