Simulator and Feature Memory  
The LEGEND 3000 SERIES contains a  
SIMULATOR that allows you to use the  
unit as though you are on the water.  
Note: International models include multiple  
languages and measurements in metres, feet  
or fathoms. Temperature includes ¡C.  
The SIMULATOR is an invaluable aid to  
USING THE LEGEND 3000 SERIES  
learning the features and functions of the LEGEND 3000 SERIES. All controls  
are operational and settings can be changed to experiment with various  
features. An indicator appears at the bottom left of the display when

The LEGEND 3000 SERIES represents a new way of thinking about fishing operating in SIMULATOR mode.  
electronics. It combines state-of-the-art electronics with the detail of a  
traditional sonar paper chart recorder to create the fishfinder of the future.  
Minimal, easy-to-understand knob controls provide access to the most  
important features. The LEGEND 3000 SERIES eliminates confusion created by  
too many buttons and menus. High technology, high performance, with “back  
to basics” operation makes the LEGEND 3000 SERIES the ideal choice of the  
serious angler.  
There are two ways to start the SIMULATOR. The method to use depends on  
whether a transducer is connected.  
Power On with No  
Transducer  
If the LEGEND 3000 SERIES is powered  
on with no transducer connected, it  
starts up in SIMULATOR mode. No other  
steps are needed. In this mode, the LEGEND 3000 SERIES does not  
remember any setting changes after power off, but defaults to the factory  
settings.  
The LEGEND 3000 SERIES uses sonar to locate and define underwater objects.  
Sonar technology is based on sound waves sent into the water in a controlled  
“beam” from the transducer. Objects within this beam reflect the sonar signal  
back. The LEGEND 3000 SERIES very accurately measures the distance to these  
objects based on the time it takes for the sonar to return. Each object (bottom,  
fish or structure) reflects the sonar uniquely, providing information about its  
makeup. The LEGEND 3000 SERIES draws this returned information on the  
display.  
Power On with Transducer Connected  
If the LEGEND 3000 SERIES is powered on with the transducer connected,  
the SIMULATOR must be turned on manually. To turn on the SIMULATOR  
manually:  
The LEGEND 3000 SERIES operates in a wide variety of water conditions, from 2'  
to 600' (2000' for the Legend 3000 Deep and 3005 Deep Models).Actual depth  
capability depends on many factors such as bottom hardness, water conditions,  
and transducer installation. All sonar units typically read to deeper depths in  
fresh water than in salt water.  
1. Press the Control Panel knob to display the list of  
options.  
2. Rotate the Control Panel knob to scroll through the list  
until Simulator is visible and is highlighted on the  
display.  
Deep Models Additional Performance  
If you purchased a Legend 3000 Deep or a Legend 3005 Deep Model, your  
Legend product is equipped with a 50kHz/200kHz dual beam transducer  
capable of performing to a depth of 2000 feet. In addition, your unit contains  
several extra features that will enhance its sonar performance in deep water.  
SONAR VIEW allows you to display the sonar information from either beam or  
both beams simultaneously. FILTER control allows the filtering algorithms to be  
turned off to show the greatest amount of sonar information. FISH ALARM, FISH  
SENSITIVITY, and FISH ID provide advanced signal processing to identify fish  
and show their depth and relative size from either beam.  
3. Turn the Range knob to turn Simulator from Off to  
On.  
4. Press the Control Panel knob to clear the screen.  
When operating with the Simulator on and the transducer connected,  
changes made to the following Control Panel choices are permanently  
remembered: Chart Speed, RTS Window, Surface Clutter, Contrast,  
White Line, Units, and in International Models, Language.

USER INTERFACE / KNOBS / LCD DISPLAY  
small increments, while turning it quickly  
makes large changes to the adjustment.  
USER INTERFACE  
The LEGEND 3000 User Interface is made up of the  
following components: knobs and the LCD Display,  
which in turn is made up of the RTS and the Chart  
Windows.  
The LCD Display  
The LEGEND 3000 SERIES uses a high-  
resolution LCD display to show sonar  
information, digital depth, temperature,  
speed and other readouts.  
Knobs  
Four knobs on the LEGEND 3000 SERIES control all  
user settings: MODE, GAIN, CONTROL PANEL and RANGE.  
A digital depth readout is always displayed  
in the upper left corner of the LCD. When  
the speed/temp accessory is connected,  
additional digital readouts (such as MPH)  
are shown below the depth. A voltage  
readout appears in the bottom left when  
the input voltage to the LEGEND 3000  
SERIES is less than 11 volts or greater than  
15 volts.  
Mode Knob  
The MODE knob selects how the LEGEND 3000 SERIES  
locates the bottom and graphs the information on  
the display. Turn the knob until the pointer aligns  
with the desired mode of operation. See Modes of  
Operation for more information.  
Gain Knob  
The GAIN knob controls the gain  
(sometimes called sensitivity) of the  
sonar receiver. Gain also powers the  
unit on or off. When the LEGEND 3000  
SERIES is off, press Gain to turn the  
unit on. Press and hold Gain to turn  
the unit off. Turn the Gain knob  
clockwise to increase the gain; turn  
counterclockwise to decrease the  
gain. As you turn the knob, only new  
sonar information being graphed  
shows the effect of the gain change.  
A depth range scale appears close to the  
right side of the LCD display. This scale  
indicates the distance from the surface of  
the water to a depth range sufficient to  
show the bottom. For example, in 18 feet of water, a 20 foot depth range  
is selected. The depth range scale can be controlled automatically or  
manually depending on the mode of operation. In AUTOMATIC and Bottom  
Lock modes, the LEGEND 3000 SERIES selects the depth range. In MANUAL  
mode, the depth range is selected by the user.  
The sonar returns received by the LEGEND 3000 SERIES are displayed along  
the depth range scale in a REAL

Increased gain is also beneficial at deeper depths to maintain a good  
bottom image and show adequate sonar returns from deep objects.  
Decreasing the gain eliminates the clutter from the display; however, if  
adjusted too low, the display may not show many faint sonar returns that  
could be fish.  
Control Panel Knob  
The CONTROL PANEL knob accesses features used to adjust some LEGEND  
3000 SERIES settings. Push the knob to display the CONTROL PANEL list, then  
rotate the knob to select a feature for adjustment. A light colored  
background indicates the selected feature. Turn the RANGE knob to adjust  
the selected feature. Remove the CONTROL PANEL list from the display by  
pushing the CONTROL PANEL knob again. If no adjustments are made after a  
few seconds, the CONTROL PANEL list is removed automatically.

USING THE LEGEND 3000 SERIES  
REAL TIME SONAR™ / CHART WINDOW  
drifting very slowly, the RTS WINDOW can show the movement of the fish  
through the transducer beam. Moving fish appear as smaller groups of lines  
that become progressively larger lines, or vice versa. A grouping of lines  
moving vertically indicates a fish changing depth.  
The sonar returns received by the LEGEND 3000 SERIES are  
displayed along the depth range scale in a REAL TIME  
SONAR™ (RTS) WINDOW and CHART WINDOW. The RTS WINDOW  
displays new sonar information within the transducer  
cone in an expanded, easy-to-see format; the CHART  
WINDOW logs old RTS WINDOW information to show a contour  
view of the bottom and structure.  
The Chart Window  
The CHART WINDOW creates a historical log of sonar returns from stored RTS  
information. As the boat moves, variations in the depth and sonar return changes are  
charted to form an image of the bottom contour. 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.  
Real Time Sonar™ (RTS)  
Window  
RTS Wide “A” scope mode  
Real Time Sonar (RTS)  
Window  
The CHART WINDOW also indicates the composition of the bottom. A hard bottom,  
such as compacted sediment or flat rock, appears as a dark, thin line across the  
display. A soft bottom, such as mud or sand, appears as a thicker line that  
contains a transition from darker to lighter grays. Bottoms made up of many rocks  
have a broken, random appearance.  
The REAL TIME SONAR (RTS)  
WINDOW shows instantaneous  
sonar returns from the bottom,  
structure and fish that are within  
the transducer beam. The RTS  
WINDOW updates with new sonar  
information up to 30 times per  
second in shallow water (deeper  
water will slow the refresh rates).  
The RTS WINDOW responds to  
quickly-changing depths in a  
way similar to a flasher type  
sonar display. Interpreting  
the RTS information requires  
some skill; comparing the  
RTS data with the data in  
the CHART WINDOW, however,  
makes the RTS information  
easy to understand.  
Sloped Bottoms  
Bottoms having a large degree of slope also present a unique picture. These  
generally have a thicker black band representing the bottom directly under the boat.  
Equal areas of gray above and below the black band represent sonar returns from  
around the boat.

the second return will be more faint,  
except in areas with a hard  
bottom.The LEGEND 3000 SERIES has a unique depth range  
feature which permits the second return to be visible  
in any depth range up to one-half the maximum depth  
of the unit. See MODES OF OPERATION for details.  
When the RTS WINDOW is wide enough, it plots the depth and intensity  
(amplitude) of a sonar return using horizontal black lines, where line length  
indicates return strength, and the vertical placement of the lines next to the  
depth range scale indicates the depth.  
Structure  
When the RTS WINDOW is narrow enough, it plots the depth and intensity of a  
The LEGEND 3000 SERIES displays structure, such as  
submerged grass, brush, trees and wrecks on the  
bottom. Structure can be distinguished by comparing  
the area just above and below the main bottom return.  
Usually structure shows as areas of dark to light gray  
on top of a dark bottom contour. The appearance of  
structure is greatly affected by boat speed and  
direction; to repeat the same image it is often  
necessary to travel the same speed and direction over  
the location where the structure was originally  
located.  
sonar return using grayscale lines, where the intensity of the sonar return is  
divided into 16 levels of grayscale, with the most intense returns shown in  
black, and less intense sonar returns shown as progressively lighter shades  
of gray. When the view is narrow enough, the combination of the grouping of  
the lines and the grayscale level helps to identify the bottom composition and  
structure. The bottom displays as the largest grouping of black horizontal  
lines, and typically has gray lines underneath. A harder bottom shows less  
gray below; a soft bottom shows more gray below. Structure appears above  
the bottom as a cluster of lines with varying lengths and gray shades.  
In any view, fish appear as smaller groupings of sonar returns between the  
bottom and surface. Often, large fish within a structure will show as a strong  
return within a grouping of smaller returns. When the boat is stationary or

important to remember that sonar cannot distinguish between  
a fish and some other object suspended in the water.  
Regardless of the object the sonar detects, it has the  
possibility of being drawn as an arch.  
The LEGEND 3000 SERIES is also capable of showing layers  
of water having different temperatures. These  
temperature differences, called thermoclines, appear  
at different depths, depending on current conditions.  
A thermocline typically appears as a continuous band  
of many gray levels moving across the display at the  
same depth. Thermoclines always appear above the  
bottom.  
Sonar Views (Deep Models Only)  
The dual beam (50/200kHz) sonar information can be  
displayed in several different views in the CHART WINDOW. In the  
200kHz view, only the sonar returns and FISH ID from the  
200kHz beam are displayed. Typically, the 200kHz  
Fish Appearance  
Schools of bait fish as well as individual fish are clearly  
visible on the LEGEND 3000 SERIES display. Bait fish appear  
as “clouds” having different shapes and sizes  
depending on the number of fish and boat speed.  
Individual fish appear as smaller black and gray lines,  
often appearing as a “fish arch.” A fish arch may form  
as the fish moves through the sonar beam. Due to the  
transducer beam angle, the distance to the fish  
decreases as the fish moves into the beam, and then  
increases as it moves out again. When the CHART  
WINDOW graphs this distance change, an arch  
appears. Boat speed, the CHART SPEED setting and  
movement of the fish greatly affect the shape of the  
arch. When the boat and the fish are moving slowly  
relative to each other, the fish creates an elongated  
arch. When the boat and the fish are moving quickly  
relative to each other, the fish creates a shorter arch.  
A partial arch forms when the fish does not move  
through the entire cone angle.  
information provides greater bottom detail up to 800' and  
works well while the boat is in motion. The 50kHz view only  
shows the sonar returns and FISH ID from the 50kHz beam.  
The 50kHz information provides depth accuracy up to 2000'  
and shows more targets in its wider beam. The Split Screen  
view shows the 50kHz and 200kHz sonar information in  
side-by-side windows on the display. The 200kHz/50kHz  
view is a composite of the 200kHz sonar information and  
the target information from the 50kHz sonar. See CONTROL  
PANELS for details on selecting the sonar views.

Fish Alarm  
FISH ALARM (Deep Models only)  
will sound when a fish (or  
other target not connected to  
the bottom) that meets the selected size criteria is  
detected by the sonar. The FISH ALARM has four different  
settings, OFF plus the three different fish symbols  
shown onscreen (see FISH ID). The 3000 Deep/3005 Deep can  
be set to alarm only large fish, (displayed as a large  
fish symbol), only large and medium fish (displayed as  
one large and one medium fish symbol), or all sizes of  
fish (displayed as one large, one medium, and one  
small fish symbol).  
The TEMP ALARM setting returns to factory default after the  
LEGEND 3000 SERIES is turned off. The factory setting is OFF.  
Note: You must select a Temp Alarm mode (INSIDE, OUTSIDE, or  
BOTH), then set the UPPER TEMP and the LOWER TEMP in order for  
this feature to work.  
The FISH ALARM setting is retained in memory after the

fish detection more sensitive (+5 = greatest  
sensitivity). Selecting a negative offset makes the fish  
detection less sensitive (-5 = least sensitivity).  
UPPER TEMP is the upper  
temperature boundary for  
the temperature alarm. The  
inside temp alarm will sound when the water  
temperature was initially above the upper temp  
boundary and then falls below it. The outside temp  
alarm will sound when the water temperature was

Before You Call Customer Support  
Many requests for repair received by Techsonic  
involve units that do not actually need repair. These  
units are returned “no problem found.” If you have a  
problem with your LEGEND 3000 SERIES, use the following  
troubleshooting guide before calling Customer  
Support or sending your unit in for repair. The LEGEND  
3000 SERIES contains several tools that can aid in  
determining if there is a problem, as well as how to  
isolate and repair a problem in many cases.  
3. There is no bottom reading visible on the display.  
There are several possible causes for this condition. If  
the loss of bottom information occurs only at high  
boat speeds, the transducer needs to be adjusted. If  
the digital depth readout is working but there is no  
bottom visible on-screen, it is possible that the depth  
range has been adjusted manually to a range lower  
than that needed to display the bottom. Also, in very  
deep water, it may be necessary to increase the GAIN  
setting manually in order to maintain a graphic  
depiction of the bottom.  
1. Nothing happens when I turn the unit on.  
Check the power cable connection at both ends. Be  
sure the cable is connected correctly to a reliable  
power source—red lead to positive, black lead to  
negative or ground. Ensure the power available at the  
mount is between 10 and 20 VDC. If the unit is wired  
through a fuse panel, ensure the panel is powered;  
accessory fuse panels often are controlled by a  
separate switch or by the boat’s ignition switch. A  
fuse also can appear to be good when in fact it is not.  
Check the fuse with a tester or replace it with a fuse  
known to be good.  
If you are using a transducer switch to connect two  
transducers to the LEGEND 3000 SERIES, make sure that the  
switch is in the correct position to connect a  
transducer, and that the transducer is submerged in  
water. (If a trolling motor transducer is selected and  
the trolling motor is out of the water, no sonar  
information will appear.)  
If none of the above solves the problem, inspect the  
transducer cable from end to end for breaks, kinks, or  
cuts in the outer casing of the cable, and repair after  
disconnecting the cable from both the unit and the  
transducer. If the transducer is connected to the unit  
through a switch, temporarily connect it directly to the  
unit and try again. If none of these items identifies an  
obvious problem, the transducer itself may be at fault.  
Be sure to include the transducer if returning the unit  
for repair.  
Check the power connection to the LEGEND 3000 SERIES. It  
is possible to force the power cable connector into  
the collector plug incorrectly. If the connector is  
reversed, the unit will not work. Examine the contacts  
on the back of the unit to ensure there is no corrosion.  
Ensure the cables are properly installed into the  
collector plug and the collector plug is properly  
seated into the LEGEND 3000 SERIES.

TECHSONIC INDUSTRIES, INC. ONE YEAR  
LIMITED WARRANTY  
We warrant the original retail purchaser that products made by Techsonic  
Industries have been manufactured free from defects in materials and  
workmanship. This warranty is effective for one year from the date of  
original retail purchase. Techsonic Industries products found to be  
defective and covered by this warranty will be replaced or repaired free of  
charge at Techsonic Industries' option and returned to the customer  
freight prepaid. Techsonic Industries' sole responsibility under this  
warranty is limited to the repair or replacement of a product that has been  
deemed defective by Techsonic Industries. Techsonic Industries is not  
responsible for charges connected with the removal of such product or  
reinstallation of replaced or repaired parts.  
6. I get gaps in the reading at high speeds.  
Your transducer needs to be adjusted. If the transducer is transom-  
mounted, there are two adjustments available to you: height and running  
angle. Make small adjustments and run the boat at high speeds to  
determine the effect. It may take several tries to optimize high speed  
operation. This can also be a result of air or turbulence in the transducer  
location caused by rivets, ribs, etc.  
This warranty does not apply to a product that has been:  
7. My unit loses power at high speeds.  
Improperly installed;  
Your LEGEND 3000 SERIES has over-voltage protection that turns the unit off  
when input voltage exceeds 20 VDC. Some outboard motors do not  
regulate the power output of the engine’s alternator effectively and can  
produce voltage in excess of 20 volts when running at high RPMs. The  
LEGEND 3000 SERIES displays input voltage in the lower left corner of the  
display when it exceeds 15 VDC. Use this readout to determine if the  
voltage exceeds 20 VDC.  
Used in an installation other than that recommended in the product

Damaged or has failed because of an accident or abnormal  
operation;  
Repaired or modified by entities other than Techsonic Industries.  
Please retain your original receipt as a proof of the purchase date. This will  
be required for in-warranty service.  
8. The screen begins to fade out. Images are not as sharp as  
normal.  
Check the input voltage. The LEGEND 3000 SERIES will display the current  
voltage on-screen if it is greater than 16 or less than 10 VDC. The voltage  
readout will appear in the bottom left corner of the screen.  
THIS WARRANTY IS EXPRESSLY IN LIEU OF ANY OTHER WARRANTIES,

INCIDENTAL OR CONSEQUENTIAL DAMAGES FOR BREACH OF ANY EXPRESS  
OR IMPLIED WARRANTY RELATING TO THE PRODUCTS.  
9. The display shows many black dots at high speeds and high  
sensitivity settings.  
You are seeing noise or interference caused by one of several sources.  
Noise can be caused by other electronic devices. Turn off any nearby  
electronics and see if the problem goes away. Noise can also be caused  
by the engine. If engine noise is causing the interference, the problem will  
intensify at higher RPMs. Increase the engine speed with the boat  
stationary to isolate this cause. Propeller cavitation can appear as noise  
on-screen. If the transducer is mounted too close to the propeller, the  
turbulence generated can interfere with the sonar signal. Ensure that the  
transducer is mounted at least 15” (38cm) from the prop.  
Some states do not allow limitations on an implied warranty, or the  
exclusion of incidental or consequential damages, so the above exclusions  
may not apply to you. You may also have other rights, which vary from  
state to state.  
A separate Warranty is provided by international distributors for the  
international models. This warranty is included by your local distributor  
and this distributor maintains local service for your unit.  
10. The screen does not display a full fish arch.  
Check the running angle of the transducer. If the running angle is too  
great, a full fish arch may not appear. Reduce the running angle of the  
transducer. Several incremental adjustments may be necessary.
