How Sonar Works  
Sonar technology is based on sound waves. The Humminbird® FishFinder uses sonar to  
locate and define structure, bottom contour and composition, as well as depth directly  
below the transducer.

Finding the Cause of Noise .................................................................................................................. 40  
Your FishFinder sends a sound wave signal and determines distance by measuring the  
time between the transmission of the sound wave and when the sound wave is  
reflected off of an object; it then uses the reflected signal to interpret location, size, and  
composition of an object.  
Humminbird® FishFinder Accessories  
Specifications

Sonar is very fast. A sound wave can travel from the surface to a depth of 240 ft  
(70 m) and back again in less than ¹⁄₄ of a second. It is unlikely that your boat can  
"outrun" this sonar signal.  
Contact Humminbird®  
42  
Single Beam Sonar  
Your Humminbird® FishFinder 585c uses a 200 kHz single beam sonar system with a  
20° area of coverage. Depth capability is affected by such factors as boat speed, wave  
action, bottom hardness, water conditions and transducer installation.

What’s On the Display  
The Humminbird® FishFinder can display a variety of useful information about the area  
under and adjacent to your boat, including the following items:  
High Sonar Intensity Return  
Depth - water depth; can be set to alarm when  
the water becomes too shallow.  
Bait Ball  
Thermoclines - layers of water with different  
temperatures that appear at different depths  
and different times of the year. A thermocline  
typically appears as a continuous band of many  
gray levels moving across the display at the  
same depth.  
Temperature - water surface temperature.  
Timer - Elapsed time with Temp/Speed Accessory.  
Distance - Distance traveled with Temp/Speed  
Accessory.  
Fish - the FishFinder displays fish as arches  
and/or fish icons, and can be set to alarm when  
a fish of a certain size is detected. When a  
target is detected, a Fish ID+TM symbol appears  
on the display with the depth displayed above  
it. The size of the symbol indicates the intensity  
of the sonar return. The unit will clearly show  
schools of Bait Fish as "clouds" of different  
shapes and sizes, depending on the number of  
fish and boat speed.  
Average Speed - Average speed reading with  
Temp/Speed Accessory.  
Second Sonar Return - when the sonar signal  
bounces between the bottom and the surface of  
the water and back again. Use the appearance  
of the second return to determine bottom  
hardness. Hard bottoms will show a strong  
second return, while soft bottoms will show a  
very weak one or none at all.  
200 kHz, Orange Fish Symbol  
Structure - where fish may be hiding.  
RTS® (Real Time Sonar) Window  
Speed - if a Temp/Speed accessory is attached,  
the FishFinder can display the speed of the boat,  
and can keep a Triplog of nautical or statute  
miles traveled.  
Battery Voltage - the voltage of the boat’s  
battery; can be set to alarm if the voltage falls  
below a certain point.  
Low Sonar Intensity Return

the bottom. Depth Range is automatically selected to keep the bottom visible on the  
display, although you can adjust it manually as well (see Sonar X-Press™ Menu). Five  
additional Digital Readouts display information from optional-purchase accessories.  
These information boxes can be customized to show only the information desired (see  
Setup Menu Tab, Select Readouts).  
Views  
The views available on your FishFinder are:  
• Sonar View  
• Zoom View  
NOTE: If the Depth number is flashing, it means that the unit is having trouble locating the  
bottom. This usually happens if the water is too deep, the transducer is out of the water, the boat  
is moving too fast, or for any other reason that the unit can’t accurately receive continuous data.  
• Big Digits View.  
Sonar View is the default view. When the VIEW key is pressed, the display cycles through  
the available views. When the EXIT key is pressed, the display cycles through the  
available views in reverse order. Any view can be hidden or displayed as part of the view  
rotation using Select View from the Advanced Setup Menu.  
Understanding Sonar History  
It is important to understand the significance of the Humminbird® display. The display  
does NOT show a literal 3-dimensional representation of what is under the water. Each  
vertical band of data received by the control head and plotted on the display represents  
something that was detected by a sonar return at a particular time. As both the boat and  
the targets (fish) may be moving, the returns are only showing a particular segment of  
time when objects were detected, not exactly where those objects are in relation to  
other objects shown on the display.  
NOTE: When you change any menu settings that affect the sonar, the view will update  
immediately (i.e. you don’t have to exit the menu to apply the change to the screen).  
Sonar View  
Sonar View presents a historical log of sonar returns. Depth is always displayed.  
Readouts for temperature and speed are automatically displayed if the appropriate  
accessory is connected. The most recent sonar returns are charted on the right side of  
the window; as new information is received, the older information is moved  
across the display to the left.  
Real Time Sonar (RTS®) Window  
A Real Time Sonar (RTS®) window appears on the right side of the display in the Sonar  
View only. The RTS® Window always updates at the fastest rate possible for depth  
conditions and shows only the returns from the bottom, structure and fish that are  
within the transducer beam. The RTS® Window plots the depth and intensity of a sonar  
return (see Sonar Menu - RTS® Window).  
Upper Range

The Wide RTS® Window  
indicates the sonar intensity

plotted return provides an  
indication of whether the  
return is weak or strong. The  
depth of the sonar return is  
indicated by the vertical  
placement of the return on  
the display depth scale.

Sonar Zoom View  
Big Digits View  
Sonar Zoom View increases the displayed resolution to separate sonar returns that are  
very close together, such as those caused by fish suspended close to the bottom or within  
structure. In Zoom View, the display is split to show a narrow slice of the full range view  
on the right and the zoomed view on the left. The full range view on the right also  
contains the Zoom Preview Box that shows what part of the full range view is shown in  
zoom view on the left; the Zoom Preview Box tracks the bottom in the full range view.  
Big Digits View provides digital data in a large, easy-to-see format. Depth is always  
displayed. Readouts for temperature, speed and Triplog information are displayed  
automatically if the appropriate accessory is connected to the system. The Triplog shows  
distance traveled, average speed, and time elapsed since the Triplog was last reset. The  
digital readouts in the Big Digits View cannot be customized.  
Big Digits View  
As the depth changes, the zoomed view updates automatically to display a magnified  
image of the bottom. The Zoom Preview Box shows where the zoomed view is in  
relation to the full range view. The Zoom Level, or magnification, is displayed in the  
lower left corner and can be changed to suit conditions (see Sonar X-Press™ Menu: Zoom  
Level). Upper and Lower Zoom Depth Range numbers indicate the depth of the water  
which is being viewed.  
Digital Depth

Bottom Presentation  
Key Functions  
As the boat moves, the unit charts the changes in depth on the display to create a profile  
of the Bottom Contour. The type of bottom can be determined from the return charted  
on the display. A Hard Bottom such as compacted sediment or flat rock appears as a  
thinner line across the display. A Soft Bottom such as mud or sand appears as a thicker  
line across the display. Rocky Bottoms have a broken, random appearance.  
Your Humminbird® user interface consists of a set of easy-to-use keys that work with  
various on-screen views and menus to give you flexibility and control over your fishing  
experience.  
POWER/LIGHT Key  
NOTE: A sloping bottom will be represented as a thicker line across the display. Also, harder bottoms  
will be typically displayed with red and softer bottoms will be typically displayed with blue.  
The POWER/LIGHT key is used to turn the FishFinder on and off, and also  
to adjust the backlight and background color of the display. Press the  
POWER/LIGHT key to turn the unit on. The Title screen is then displayed until the  
FishFinder begins sonar operation.  
The sonar returns from the bottom, structure and fish can be represented as either  
Structure ID®, or WhiteLine®. See Sonar X-Press™ Menu: Bottom View for details on how  
to set the bottom view.  
To adjust the backlight, or to adjust the display background  
color, press the POWER/LIGHT key to access the Light and  
Background menu. Use the 4-WAY Cursor key to select Light or  
Structure ID® represents weak returns in blue and strong  
returns in red.  
Background and then use the LEFT or RIGHT Cursor key to  
change the settings. Press EXIT to exit the Light and Background menu.  
Press and hold the POWER/LIGHT key for 3 seconds to turn the unit off. A message will  
appear telling you how many seconds there are until shutdown occurs. Your FishFinder  
should always be turned off using the POWER/LIGHT key. This will ensure that  
shutdown occurs properly and any menu settings will be saved.  
VIEW Key  
The VIEW key is used to cycle through all available views. Press the VIEW  
key to advance to the next view. Repeatedly pressing VIEW cycles  
through all views available. Views can be hidden to optimize the system to your fishing  
requirements (see Setup Menu Tab: Select Views, Advanced).  
WhiteLine® highlights the strongest sonar returns in  
white resulting in a distinctive outline. This has the  
benefit of clearly defining the bottom on the display.

Simulator  
System Status  
Use the Simulator to learn how to use your FishFinder before taking your boat on the  
water. The Simulator is a very powerful tool that simulates on the water operation,  
providing a randomly-updated display. We recommend going through this manual  
while using the Simulator, since all of the menus function and affect the display the way  
they actually do when in Normal operating state.  
Use System Status to view system connections and  
to conduct a unit self-test.  
The following screens are displayed in turn when  
you press the VIEW button when using System  
Status:  
NOTE: To get the full benefit of the Simulator, it is important to select Simulator manually from  
the Start-Up Options menu as opposed to letting the FishFinder enter Simulator automatically (as  
it will if a transducer is not connected and you do nothing during power up). Manually selecting  
Simulator from the Start-Up Options menu allows you to pre-configure your FishFinder for on the  
water operation. Any menu changes you make will be saved for later use.

Sonar X-Press™ Menu  
Sensitivity  
The Sonar X-Press™ menu provides access to the settings  
most frequently-used. Press the MENU key once while in  
any of the Sonar Views to access the Sonar X-Press™ menu.  
Sensitivity controls how much detail is shown on the  
display. Increasing the sensitivity shows more sonar returns from small baitfish and  
suspended debris in the water; however, the display may become too cluttered. When  
operating in very clear water or greater depths, increased sensitivity shows weaker  
returns that may be of interest. Decreasing the sensitivity eliminates the clutter from  
the display that is sometimes present in murky or muddy water. If Sensitivity is adjusted  
too low, the display may not show many sonar returns that could be fish.  
NOTE: Upper Range only appears in Advanced User Mode when  
in Sonar or Big Digits View.  
NOTE: Zoom Level only appears in Sonar Zoom View.

Upper Range  
(Advanced: Sonar and Big Digits Views Only)  
Chart Speed  
Chart Speed determines the speed at which the sonar  
information moves across the display, and consequently the amount of detail shown. A  
faster speed shows more information in the Sonar View and is preferred by most  
anglers; however, the sonar information moves across the display quickly. A slower  
speed keeps the information on the display longer, but the bottom and fish details  
become compressed and may be difficult to interpret. Regardless of the Chart Speed  
setting, the RTS® Window will update at the maximum rate possible for the depth  
conditions. Adjust Chart Speed to your personal preference.  
Upper Range sets the shallowest depth range that will be displayed on the Sonar and Big  
Digits Views. The Upper Range menu choice is available when User Mode is set to  
Advanced (see Setup Menu Tab: User Mode). Upper Range is often used with Lower Range.  
For example, if you are only interested in the area between 20 and 50 feet deep, you should set  
the Upper Depth Range to 20 and the Lower Depth Range to 50. The Sonar View will then show  
the 30 foot area between 20 and 50, and will not show the surface or the bottom (assuming the  
bottom is deeper than 50 feet), and will show greater detail for that area between 20 and 50 feet.  
To adjust the Chart Speed:  
To adjust the Upper Range:  
1. Highlight Chart Speed on the Sonar X-Press™ menu.  
1. Make sure you are in Advanced Mode, then highlight Upper Range on the Sonar  
X-Press™ menu.  
2. Use the LEFT or RIGHT 4-Way Cursor Control keys to increase or decrease the Chart  
Speed setting. (1-9, Ultra, where 1 = Slow, 9 = Fast, Ultra = Fastest, Default = 4)  
2. Use the LEFT or RIGHT 4-Way Cursor Control keys to increase or decrease the  
Upper Range setting. (0 to 990 feet or 0 to 327 meters [International Models  
Only], Default = 0)  
Bottom View  
Bottom View selects the method used to represent  
bottom and structure on the display. Structure ID® represents weak returns in blue and  
strong returns in red. WhiteLine® highlights the strongest sonar returns in white  
resulting in a distinctive outline. This has the benefit of clearly defining the bottom on  
the display. (See Bottom Presentation for more information.)  
Lower Range  
Lower Range sets the deepest depth range that will be  
displayed. Automatic is the default setting. When in automatic mode, the lower range  
will be adjusted by the unit to follow the bottom. Selecting a specific setting locks the  
depth range into Manual mode. Use both Upper and Lower Range together to view a  
specific depth range manually when looking for fish or bottom structure.

Fish Sensitivity  
Fish ID+™  
Fish Sensitivity adjusts the threshold of the Fish ID+™  
detection algorithms. Selecting a higher setting allows weaker returns to be displayed as  
fish. This is useful for identifying smaller fish species or baitfish. Selecting a lower setting  
displays fewer fish from weak sonar returns. This is helpful when seeking larger species  
of fish. Fish Sensitivity is used in conjunction with Fish ID+™. Fish ID+™ must be On for  
Fish Sensitivity to affect the ability of the FishFinder to identify sonar returns as fish.  
Fish ID+™ uses advanced signal processing to interpret  
sonar returns, and will display a Fish Symbol when very selective requirements are met.  
When a fish is detected, a fish icon and its depth are displayed above the return that has  
been classified as being a fish. Three different fish size icons represent the intensity of  
the sonar return, and provide an indicator of relative fish size. Single beam sonar  
FishFinders represent targets as orange Fish Symbols.  
To change the Fish Sensitivity setting:  
1. Highlight Fish Sensitivity on the Sonar main menu.  
200 kHz Fish Symbols  
2. Use the LEFT or RIGHT 4-Way Cursor Control keys to change the Fish Sensitivity  
setting. (Low = 1, High = 10, Default = 5)  
When Fish ID+™ is turned off, the FishFinder shows only the raw sonar returns on the  
display. These returns will often result in "arches" forming on the display, indicating  
potential targets. Due to the transducer beam angle, the distance to a fish decreases as  
the fish moves into the beam, and then increases as it moves out again, creating a Fish  
Arch when this distance change is shown on the display. Boat speed, chart speed, and  
the position of the fish within the sonar beam greatly affect the shape of the arch.  
Real Time Sonar (RTS®) Window  
(Sonar View Only)  
RTS® Window sets the RTS® window to either Wide or Narrow, or turns it off in the  
Sonar View. The RTS® window always updates at the fastest rate possible and only  
displays returns that are within the transducer beam. (See Real Time Sonar (RTS®)  
Window for additional detail).

Water Type  
(Advanced)  
Noise Filter  
(Advanced)  
Water Type configures your unit for operation in fresh or salt water. The Water Type  
menu choice is available when User Mode is set to Advanced (see Setup Menu Tab: User  
Mode).  
Noise Filter adjusts the sonar Noise Filter to limit interference on the display from  
sources such as your boat engine, turbulence, or other sonar devices. The Noise Filter  
menu choice is available when User Mode is set to Advanced (see Setup Menu Tab: User  
Mode).  
NOTE: In salt water, what would be considered a large fish might be 2 to 10 times bigger than a  
large fish in fresh water (depending on the type of fish you are seeking). The salt water setting  
allows for a greater range in fish size adjustment to account for this. Also, make sure that the  
Water Type is set accurately, especially in salt water, as this affects the accuracy of deep water  
depth readings.  
NOTE: The Off setting removes all filtering; Low, Medium and High settings add progressive  
filtering of the sonar returns. In some deep water situations, the High setting may actually  
hinder your FishFinder’s ability to find the bottom.  
To change the Noise Filter setting:  
To change the Water Type setting:  
1. Make sure you are in Advanced User Mode, then highlight Noise Filter on the

Max Depth  
(Advanced)  
Max Depth adjusts the maximum depth of operation. The performance of your  
FishFinder can be tuned to the maximum depth you will be fishing in by setting the  
Max Depth. When a maximum depth is set, your FishFinder will not attempt to acquire  
sonar data below that depth, thus increasing overall performance. When Max Depth is  
set to Auto, the FishFinder will acquire bottom readings as needed (within the capacity  
of the unit). If the bottom is deeper than the Max Depth setting, the digital depth  
readout will flash, indicating that the FishFinder cannot locate the bottom. The Max  
Depth menu choice is available when User Mode is set to Advanced (see Setup Menu  
Tab: User Mode).  
To change the Max Depth setting:  
1. Make sure you are in Advanced User Mode, then highlight Max Depth on the  
Sonar main menu.

Display Problems  
Troubleshooting  
There are several main conditions or sources of possible interference that may cause  
problems with the quality of the information displayed on the control head. Look in the  
following table for some symptoms of display problems and possible solutions:  
Before contacting the Humminbird® Customer Resource Center, please read the  
following section. Taking the time to review these troubleshooting guidelines may  
allow you to solve a performance problem yourself, and therefore avoid sending your  
unit back for repair.  
Problem  
Possible Cause  
The control head loses power at  
high speeds.  
If the power output of your boat’s engine is  
unregulated, the control head may be protecting  
itself using its over-voltage protection feature. Make  
sure the input voltage does not exceed 20 Volts.  
FishFinder Doesn’t Power Up  
If your FishFinder doesn’t power up, use the Installation Guide that also comes with it  
for specific confirmation details, making sure that:  
• the power cable is properly connected to the FishFinder control head,  
• the power cable is wired correctly, with red to positive battery terminal and  
black to negative terminal or ground  
• the fuse is operational  
• the battery voltage of the power connector is at least 10 Volts.  
When the boat moves at higher  
speeds, the bottom disappears  
or suddenly weakens, or the  
display contains gaps.  
The transducer position may need to be adjusted. A  
mix of air and water flowing around the transducer  
(cavitation) may be interfering with the inter-  
pretation of sonar data. See your Installation Guide  
for suggestions on adjusting the transducer position.  
Correct any known problems, including removing corrosion from the battery terminals  
or wiring, or actually replacing the battery if necessary.  
Electrical noise from the boat’s engine may be  
interfering with sonar reception. See Finding the  
Cause of Noise for more information.  
FishFinder Defaults to Simulator with a Transducer Attached  
There are no fish detected,  
even when you know they are  
in the water under the boat,  
or sonar readings seem weak  
or faulty.  
Sonar readings may be affected if the transducer is  
not positioned correctly (i.e. mounted at an angle, not  
straight down), or there is some kind of mechanical  
interference, either because it is mounted inside a  
hull that is too thick for proper sonar transmission,  
the bond between the transducer and the hull is not  
airtight, or because the transducer is dirty. Check with  
your Installation Guide for guidance on re-positioning  
the transducer, and make sure the transducer is clean.  
A connected and functioning transducer will cause the newly-started FishFinder to go  
into Normal operating mode automatically. If, when you power up the FishFinder, it  
goes into Simulator mode automatically, even though a transducer is already  
connected, this means that the control head is not detecting the transducer. Perform  
the following troubleshooting tasks:  
• Using the Installation Guide that also comes with your FishFinder, check to  
make sure that the transducer cable is securely connected to the FishFinder.  
Reconnect if necessary, and power up the FishFinder again to see if this fixes  
the problem.  
Low battery voltage may be affecting the power of  
signal transmission.  
• Replace the transducer with a known good transducer if available and power  
up the control head again.  
• Check the transducer cable and connector. Replace the transducer if the cable is  
damaged or corroded.  
Electrical noise from the boat’s engine may be  
interfering with sonar reception. See Finding the  
Cause of Noise for more information.

Finding the Cause of Noise  
Specifications  
Electrical noise usually affects the display with many black dots at high speeds, and high  
sensitivity readings. One or more of the following sources can cause noise or interference:  
Depth Capability ................................................................................ 1000 ft (330 m)  
Possible Source of Noise  
Other electronic devices  
How to Isolate It  
Power Output .................................................................................. 300 Watts (RMS)  
Turn off any nearby electronic devices to see if the  
problem goes away, then turn them on one at a time to  
see if the noise re-appears.

Operating Frequency.............................................................. 200 kHz Single Beam  
Area of Coverage ................................................................ 20° @ -10 dB in 200 kHz  
The boat’s engine  
To determine whether the boat’s engine is the source of  
the noise, increase the RPMs while the boat is in neutral  
and stationary to see if the noise increases  
proportionately; if noise appears when you rev the  
engine, the problem could be the spark plugs,  
alternator, or tachometer wiring. Replace the spark  
plugs with resistor plugs, install an alternator filter, or  
route the control head power and transducer cables  
away from the engine wiring.

AND a transducer with temperature built in is connected at the same time, the TS-W or TG-W  
accessory will override the temperature built in to the transducer.
