Fishfi nder 80
The Fishfinder 80 is able to display a variety of useful
information about the underwater environment. Below
are a few things the unit will help you see.
Water Depth
The unit displays water depth and can provide a warn-
ing when a specific depth is encountered. The Depth
Scale is displayed from top to bottom along the right
side of the display. Messages and Alarm Icons are
displayed along the bottom.
Water Temperature
The unit will display the water temperature at the
transducer.
Fish
The unit displays fish as arches or fish symbols in 3 sizes
and can alert you when a fish is detected.
Thermocline and Structure
GARMIN’s See-Thru
®
technology can display more than
just the thermocline and structure, the unit displays fish
in and below the thermocline, trees, brush and deadfall.
Bottom Shape and Type
Garmin’s unique DCG
®
(Depth Control Gain) system
provides a clear graphic representation of the bottom
type and its shape.
ARROW KEYS
The UP and DOWN ARROW keys are used to
select items on the Adjustment Bar and Setup
menu.
ENTER Key
The ENTER key is used to activate/deactivate
Adjustment Bar and Setup Menu data fields for
review or changes.
MENU Key
The MENU key is used to activate/deactivate
Adjustment and Setup Menus.
POWER Key
The POWER Key is used to turn the unit on/off
and to activate the display backlight. Press and
hold to turn the unit on/off. Press briefly and
release to activate the backlight. To change the
backlight level, press the POWER key repeat-
edly to cycle between Off, Low and High.
ENTER
MENU
Range
‘Range’ is used to set the display depth range. The unit can
be set to automatically track the bottom or set to a user-specified
range. Available settings are: ‘Auto’ (default) and 15-600 ft.
Gain
‘Gain’ allows the user to control the sensitivity of the unit’s
sonar receiver. This provides some flexibility in what is seen on
the display. To see more detail, increase the receiver sensitivity
by selecting a higher gain (+). If there is too much detail or if the
screen is cluttered, lowering the sensitivity (-) may increase the clarity of
the display. Available settings are: ‘NRML’ (Normal, default) and +5 to -5.
Zoom
‘Zoom’ is used to quickly select a display zoom scale. Available settings
are: ‘OFF’ (default), ‘2X’ and ‘4X’ zoom.
View
‘View’ is available only when a Zoom scale other than ‘OFF’ is selected.
This setting allows you to select a specific zoom area to view on the display
or allow the unit to automatically select a zoomed viewing area based on
the bottom. When adjusting this setting, the top and bottom numbers will
reflect the zoomed view depth range.
Setup Menu — Depth Alarm
‘Depth Alarm’ can be set to sound a shallow water warning at a
depth determined by the user. (If the ‘Depth Alarm’ is set when ‘Units’
are changed, the ‘Depth Alarm’ will be defaulted to ‘Off’.) This alarm
may be set to ‘Off’
(default) or from 1-600 ft.
Fish Alarm
‘Fish Alarm’ can be confi gured to sound when the unit detects what it determines to
be a fi sh. The alarm selections are: ‘Off’
(default) or ‘On’.
Fish ID
‘Fish ID’ allows the user to determine how the chart will display underwater
targets and background information. If ‘Fish ID’ is set to ‘OFF’, the unit will display
all of the available information about the underwater environment. If a fish symbol
is selected, the chart will display only the information related to that symbol (large,
medium and small sizes).
— All available information will be displayed.
— Suspended targets displayed as symbols. No background information will be
displayed in this mode.
— Same as above with target depth displayed.
— Suspended targets will display as symbols. In this mode background
information will still be displayed making fi sh identifi cation easier.
— Same as above with target depth displayed.
(default)
Using the Adjustment Bar
The Adjustment Bar allows direct access to the settings most
commonly changed while using the unit. These include the depth
Range, Gain, Zoom and the View settings. Current Adjustment Bar
settings may be viewed by pressing the MENU key. Press MENU
again to hide the window or to exit any window. The current
adjustment option will always display in the upper left of the
display.
To immediately change the current adjustment option,
press the UP or DOWN ARROW key. If you wish to review
the available settings before making a change, press the ENTER key to activate the
adjustment window.
To change a setting on the unit:
1. Press MENU, then using the UP or DOWN ARROW key, move the selection arrow
to the desired option and press ENTER. Choose ‘Setup’ for the main Setup Menu.
2. Using the UP or DOWN ARROW key move the selection arrow to the desired
setting and press ENTER. (The selection arrow will wrap when you reach the end
of a menu and adjustment window. If holding the ARROW key down, release then
press.) Holding down on an ARROW key will rapidly advance the selection speed.
3. To close a setting or menu window, press MENU.
Setup Menu (cont.) — Whiteline
‘Whiteline’ controls how the unit displays information about
the bottom type (hard or soft). With the Whiteline ‘OFF’, the
bottom return will display as solid black and contain no infor-
mation on bottom hardness. With Whiteline ‘ON’, the bottom
return will become a black & white pattern and can be used to
determine bottom hardness. A hard bottom will return a stronger
signal and display a thicker bottom layer. A weaker (soft) bottom
return will display a thinner bottom layer. The selections are: ‘Off’ or
‘On’
(default).
Noise Reject
‘Noise Reject’ helps fi lter unwanted noise from the chart (espe-
cially when moving at faster speeds) and can be turned ‘OFF’ or set
to a fi xed value from 1-100%. Remember when setting the ‘Noise
Reject’, the higher the noise rejection setting, the more likely the
unit will not show fi sh or structure. The selections are: 1-100%
(default 50%) or ‘Off’.
Units
‘Units’ can be confi gured to display measurements in Feet (ft,
default), Meters (m) or Fathoms (fa). (If the ‘Depth Alarm’ is set when
‘Units’ are changed, the ‘Depth Alarm’ will be defaulted to ‘Off’)
Setup Menu (cont.) — Simulator
The Fishfinder 80 comes with a built-in simulator mode that will allow the user
to practice and learn the operation of the unit at home rather than on the water.
The unit will indicate that it is running the simulator mode by displaying a message
in the lower left of the display. While in the simulator mode, the unit will display a
random bottom scene and the Fishfinder 80 can be controlled (except Noise Reject
and Gain) just as if it were on the water. To exit the Simulator, turn the unit off. If no
keys are pressed for 2 minutes, the unit will automatically reset while in simulator
mode. If the unit does not detect a transducer attached, it will automatically start in
Simulator mode.
Contrast
‘Contrast’ of the display may need to be adjusted to compensate for
light levels or viewing angles.
Defaults
This option allows you to restore the factory default settings for the
unit.
Understanding Sonar
To understand what the unit is displaying, it is important to have a general knowl-
edge of how the unit works and how it determines what to display. The unit operates by
transmitting sound waves toward the bottom of a lake, stream or seabed in a cone shaped
pattern. The area covered by the transmitted sound waves is determined by the cone
angle of the transducer and the water depth. Using
Garmin’s standard 20° transducer, the coverage is
approximately 1/3rd of the water depth. The cover-
age area at a 30 foot depth is approximately a 10
foot diameter circle.
When a transmitted soundwave strikes an
underwater object, sound is reflected back to the
transducer. The transducer collects the reflected
sound waves and sends the data to the unit to be
processed and displayed on the chart. The under-
water data is displayed on the chart in the order
that it is returned: first returned—first on the chart.
Generally speaking, if the only thing between the
transducer and the bottom is water, the first strong
return will come from the bottom directly below
the transducer. The first strong return sets (cont.)
Whiteline ‘ON’
Whiteline ‘OFF’
the bottom level. Weaker secondary
returns provide the detailed data. This
fi sh is currently in a Dead Zone and is
not detected by the sonar. The fi sh is in
the coverage area of the transducer, but
remember the fi rst strong return sets
the bottom level. The fi sh will never
be detected since the bottom level will
never be set below the fi sh. The fi sh
on the right side of the display (shown
in light grey) will be detected and
displayed when the transducer cone
passes over the fi sh.
It is important to understand that
the unit does not display a 3-D repre-
sentation of the underwater environ-
ment. The unit can display multiple
things (such as a fi sh and a tree) at the
same time, but can not determine where the return originated only when it was received.
Remember that the Fishfi nder displays a 2D picture of the underwater environment. The
fi sh and tree could be located anywhere in the coverage area at that slice of time.
