HOW SONAR WORKS
HOW SONAR WORKS
Your Pro Craft unit uses sonar to
locate and define underwater objects,
define the bottom terrain, as well as
determine distance.
Sonar technology is based on sound
waves. Your Pro Craft unit sends out
a sound wave signal. With this signal
it determines distance by measuring
the time between the transmission of
the sound wave and when the sound
wave is reflected off an object. Your
Pro Craft uses the reflected signal to
interpret location, size and composi-
tion of an object.
Sonar is very fast. A sound wave can travel from the surface to a depth of
240' (70m) and back again in less than 1/10 of a second. It is unlikely that
your boat can "outrun" this sonar signal.
The Pro Craft unit is a dual frequency, dual beam unit, and generates two
distinct sonar signals - one narrow, one wide. Each signal is optimized for
a particular purpose. First, the center beam transmits at a frequency of 200
kHz in a 20 degree (narrow) symmetrical pattern for greater depth capa-
bility and excellent detail. Information from this center beam is used to
draw the graphic representation of the bottom on the display.
Second, the wide beam transmits at a frequency of 83 kHz in a 53 degree
(wide) symmetrical pattern for greater area of coverage. Information from
the wide beam is used to accurately detect the presence and location of
fish. A wide beam has a large area of coverage but limited resolution of
detail. A narrow beam has excellent detail, but within a limited area
of coverage.
The combination of the two beams and dual frequencies provides the com-
bination of a large area of coverage and a high level of detail.

USING THE PRO CRAFT UNIT
SIMULATOR OPERATION
Actual depth capability depends on factors such as bottom hardness, water
conditions, and transducer installation. Units will typically read to deeper
depths in fresh water than in salt water.
SIMULATOR OPERATION
The Pro Craft unit contains a simulator that
allows you to use the unit as if you are on the
water. The simulator is invaluable for learn-
ing how to operate the Pro Craft unit.
There are two ways to start the simulator. If
the unit is powered off, press and hold the
POWER button for approximately three sec-
onds until you hear a continuous chirp.
The simulator can also be started by selecting the Simulator option on the
start-up screen after you power-up the unit. When this screen is shown,
simply press the DOWN ARROW until “Simulator”is highlighted. When the
screen times out, the unit will be in simulator mode.
When in simulator operation, the Pro Craft unit responds to control inputs
as if it is in actual operation, so feel free to experiment, or to customize the
unit for your particular operation.
To exit Simulator mode, power the unit off.
When in simulator mode, the word “simulator” appears on the
display, blinking on and off, indicating the information on-screen
is not real sonar data.
FEATURE MEMORY
If your Pro Craft unit is installed with a transducer connected, any changes
you make to the set-up or User Options (see Control Functions) while in
Simulator are retained in the unit’s memory. This allows you to use simula-
tor to experiment with the various set-up options, and retain your selected
settings for normal operation.

4
If you are using the Pro Craft unit in Simulator when no transducer is con-
nected, any selected options are lost when the unit is powered off. The Pro
Craft unit will return to Factory Settings, or options selected when last used
with a transducer, if no transducer is connected.
IMPORTANT: A transducer must be connected to the Pro Craft unit
in order to retain user settings selected when in simulator mode.
If no transducer is detected, the unit defaults to pre-selected
options when powered off.
What You See On-Screen
Your Pro Craft unit uses a 128 V x 64 H
matrix FSTN LCD display. This display
provides outstanding viewability in all
light conditions over a wide range of
temperatures.
At initial power-up, the Pro Craft unit
uses settings that were set at the facto-
ry. After initial use, the Pro Craft unit will
remember the settings you enter.
There are several elements on-screen
that are common to all modes of opera-
tion.
Temperature/Speed. The initial screen layout takes one of two basic forms
depending on whether the optional Temp/Speed accessory is installed. Figure
A shows the default view when the Temp/Speed accessory is installed. Figure B
shows the default view when the Temp/Speed accessory is not installed.
Depth. The digital depth number shows the water depth directly beneath the
transducer location.
Depth Range. The depth range is shown to the right of the screen. The upper
number is 0 indicating the surface of the water. The lower number is one of
the nine depth ranges available that best match the depth of the water. As the
USING THE PRO CRAFT UNIT

depth of the water changes, the range
changes as necessary in order to retain a
bottom representation on-screen.
When in Auto mode, the horizontal line
at the top of the screen is the “zero
line,”representing the surface of the
water. Occasionally there is a gap in this
line. This gap indicates the unit is up-
dating the display even if the bottom is
not visible on-screen, or if the bottom
information is not changing.
New sonar information appears on the
right side of the graphic area of the dis-
play and moves to the left as new infor-
mation is displayed. The Pro Craft unit
automatically selects the appropriate
depth range to show the depth of water beneath the transducer. This
range is selected so the bottom representation is typically shown about 2/3
down the display.
Bottom. The graphic depiction of the
bottom provides an effective tool for
understanding the composition of the
bottom. If the bottom is hard and
smooth, the bottom depiction is narrow
and dense. If the bottom is soft mud or
sand, the depiction will be thick and less
dense. This indicates much of the signal
is absorbed by the soft bottom. If the
bottom is rocky or rugged in composi-
tion, the depiction is of varying density
and textured in appearance.
Wave action also affects the bottom
depiction. The information drawn is a
distance measurement, so if the boat is

moving up and down over flat bottom, the bottom depiction often appears
in regular variations that match wave timing.
Structure. Structure is defined as any object physically attached to the bot-
tom. The sonar configuration of the Pro Craft unit is optimized to give the
most accurate depiction of bottom structure possible. Grass, trees, stumps,
wrecks or other debris are accurately displayed, however the depiction of
these objects varies with boat speed and direction. The best way to learn to
interpret structure is to operate the Pro Craft unit over a variety of known
conditions and experiment with user functions to best represent those con-
ditions on-screen.
Surface Clutter. Surface clutter is the layer of water near the surface that
is rich in algae and other growth, and often is aerated by wind or wave
action. This area of water interferes with sonar transmission and often
appears on-screen as regular clusters of individual dots near the “0”line.
Thermoclines. Thermoclines are sharp
differences in water temperature.
These are easily identified by the con-
tinuous nature of the return.
Second Returns. When a sonar signal
is reflected off the bottom back to the
transducer, there is often enough ener-
gy left in the signal to be reflected off
the surface of the water back to the
bottom a second time. Second returns
appear as a slightly weaker bottom
representation exactly twice the depth
of the primary bottom return. The sec-
ond return is most likely to occur in
shallow water and in areas of relatively
hard bottom.
Fish ID. The Pro Craft unit uses advanced signal processing to further eval-
uate any sonar return between the surface and the bottom. For instance, a
small school of bait fish usually appears as a dense cluster of individual dots.
If the return meets certain additional criteria, a fish symbol will be assigned.
USING THE PRO CRAFT UNIT
WHAT YOU SEE ON SCREEN
Thermocline Second Return

There are three different size fish sym-
bols used to indicate the intensity of the
sonar return. While signal intensity is a
good indicator of relative fish size, differ-
ent species of fish have different sonar
characteristics, so it is not always possi-
ble to distinguish fish size between vary-
ing species. The signal intensity is "nor-
malized" for depth so that a small fish
close to the boat does not appear as a
large fish symbol.
ID+ adds an additional piece of informa-
tion to help the user locate fish. On
selected fish symbols, the digital depth
of the designated fish is drawn to help
locate the fish vertically. This is especially
helpful in setting bait depths or for downrigger operation.
The fish symbols indicate the sonar beam the fish is detected in. This
gives you a reliable indicator of side to side location of the fish relative to
the boat. Fish symbols that are hollow are detected in the wide beam and
are around the boat. Solid fish symbols represent fish detected in the nar-
row beam and are directly under the boat.
CONTROL FUNCTIONS
The Pro Craft unit uses a simple five button keypad for
all user input. Press any button and an audible “chirp”
confirms the control input. If a button has no function
or is inappropriate for the situation, an audible “error”
is heard. The unit sounds multiple chirps.
Power. The Power button powers the Pro Craft unit
up for normal operation. When the unit is on, POWER
turns the unit off. POWER can also be used to go
directly into Simulator mode. To enter simulator, with
the unit powered off, press and hold POWER for sever-

Light. LIGHT controls the unit’s display backlight. With the unit powered
on, press LIGHT once to turn the backlight on “high.”Press LIGHT a sec-
ond time to turn the backlight on “low,”and a third time turns the back-
light off. The backlight is very effective for low-light and nighttime opera-
tion. When the backlight is on, the Pro Craft unit will consume more power
than with the backlight off. This is important when using the Pro Craft unit
in a portable configuration powered by a separate battery, or when pow-
ering the unit from a trolling motor battery.
When powering the unit from a battery such as in portable applications,
you can prolong the battery life by using the backlight at a minimum.
The three lower buttons, MENU, UP ARROW, and DOWN ARROW work
together to control the Pro Craft unit menu-controlled user functions.
Menu. MENU displays a menu on-screen
for adjustment. In normal operation,
pressing MENU repeatedly cycles through
all available menu headings. When a
menu heading displays, the full menu
appears after a short pause. A menu remains on-screen for several seconds,
and can be adjusted by using the ARROW keys. If no adjustment is made
in the allotted time, the menu disappears. If you want the menu to remain
on-screen longer press and hold MENU—the menu will remain on-screen
indefinitely. Once you release the menu button, the screen will time out.
Once a menu times out, it is still considered the active menu. Press MENU
to bring up the last menu used.
Arrow Keys. The UP ARROW and DOWN ARROW make adjustments to
menu functions. On the left side of every menu there are UP ARROW and
DOWN ARROW symbols. The symbols indicate which ARROW button has
a function in a particular situation. Either one or both ARROW buttons can
be used to adjust the menu function. A hollow ARROW symbol means the
corresponding ARROW button has no function. Pressing that button will
result in no adjustment and the “error”audible will be heard. A solid
ARROW symbol means the corresponding ARROW button can be used to
affect the menu adjustment.

CONTROL FUNCTIONS
Menu Heading

The ARROW buttons often can be used
when no menu is on-screen. In these situ-
ations, pressing the ARROW button
affects the function of the active (last-
used) menu. This is a short-cut to menu
operation. The menu appears on-screen
while the adjustment is made and times out. A frequently used menu can
be adjusted very quickly using this technique.
After an adjustment is made to a menu function, the menu times out after
a few seconds and the unit returns to normal operation.
Menu Layout. All menus use the same basic layout. The heading at the
top describes the menu function. The UP ARROW and DOWN ARROW
symbols to the left of the menu indicate which buttons are available for
adjustment. In menus that have several possible settings, a range of adjust-
ment indicator shows the total range available and the current setting.
Within the menu are the options available. The selected option or current
setting is highlighted in the black box. If no adjustment is made, this is the
selected setting. Press an ARROW button while the menu is displayed to
select another option.
Several of the menus are multi-step. In some situations if an adjustment is
made, additional options become available for further adjustment. Exam-
ples of these multi-step menus are Depth Range, Depth Alarm and Zoom.

Sensitivity. The Sensitivity function controls
the sensitivity of the sonar receiver. The Pro
Craft unit automatically adjusts the level of
receiver sensitivity based on a number of fac-
tors including the depth of the water and the
level of noise present. Noise can be caused by
other electronic devices, engines, trolling
motors, propeller cavitation and hydrodynamic
flow among others.
The user has the option of adjusting the Sensitivity higher or lower based
on personal preference. You can select one of 11 sensitivity settings from -
5 to +5. A setting of 0 (factory setting) has no effect on the automatic sen-
sitivity control. Increasing the sensitivity (+1 through +5) enables the unit to
display the information from progressively smaller sonar returns. By
decreasing the sensitivity bias (-1 through -5), the unit effectively filters
small sonar returns.
In murky or muddy water, it is often helpful to reduce the sensitivity. This
prevents the display from being clut-
tered with sonar returns from debris or
suspended particles. In very clear or
very deep water, it may be helpful to
increase the sensitivity since even the
smallest sonar return may be of interest
to the user.
To adjust Sensitivity, press MENU
repeatedly until the Sensitivity heading
is displayed. When the Sensitivity menu
appears, use the UP ARROW to
increase the sensitivity, or the DOWN
ARROW to reduce sensitivity. To
sequence through the available set-
tings, press and hold either ARROW
button. Release the button at the set-
ting you want to change.

setting is in affect. If additional time is needed to study a menu, press and
hold the MENU button and the menu will remain on-screen indefinitely. If
you need to make an additional adjustment, press the UP ARROW or
DOWN ARROW button.
Depth Range. The Depth Range function
controls the vertical distance displayed on
the graphic area of the display. There are
nine depth ranges available. The top of the
range is always 0, or the surface of the
water. Ranges of 0–15', 0–30', 0–60',
0–120', 0–180', 0–240', 0–360', 0–480', and 0–600' are available. In the
metric version, ranges of 0–5, 0–10, 0–20, 0–40, 0–60, 0–80, 0–110,
0–150, and 0–185 meters are available.The range that positions the bot-
tom depiction closest to the bottom of the screen, will best utilize the avail-
able display resolution.
The Pro Craft unit automatically adjusts
the depth range depending on the depth
of the water. The unit tries to maintain the
bottom depiction about 2/3 down the
total range (for example, in 20' (6m) of
water, the 0-30' (0-10m) range would be
selected). This provides the best display
resolution and therefore the best target
separation possible.
The Depth Range can be adjusted manually. Press MENU repeatedly until
the Depth Range menu is visible. Two options are available: Auto and Man-
ual.
The manual setting enables you to adjust
the current depth range setting. The unit
no longer adjusts the Depth Range to the
most appropriate range for bottom dis-
play. Often, the bottom may not be visible
on-screen. The digital depth readout

12
always determines the depth of the
bottom, even if it is not visible
on-screen.
Using manual Depth Range control,
you can view sonar information from
the area near the surface in great
detail.
To return to automatic Depth Range
control, press the MENU button until
the Depth Range menu appears on-
screen and use the UP ARROW to
select AUTO.
Zoom. Zoom is similar to Depth Range
because it controls the range of information
displayed on screen. Zoom, however,
allows selection of ranges beneath the surface
so any area of water between the surface and
the bottom can be enlarged to provide more
detailed information. By using the full display to
show a small area of coverage, the effective dis-
play resolution is increased, and the unit’s ability
to separate close targets is enhanced.
There are four Zoom ranges available: 7
1/2' (2m), 15' (5m), 30' (10m), and 60'
(20m). These ranges are not directly user
controlled but are instead dependent on
the current depth range. In shallow water,
when the 15' (5m) or 30' (10m) range is in
use, the Zoom range is 7 1/2' (2m). If the
60' (20m) or 120' (40m) range is in use, the
Zoom range is 15' (5m), if a 180'-480' (60-
150m) depth range is in use, the Zoom
range is 30' (10m), and if the 600' (185m)
range is in use, the Zoom range is 60'
(20m).

The Zoom range is shown on the left side of the
screen and full range information is shown on the
right side of the display. Zoom can either operate
automatically, in which the Zoom range is constantly
adjusted to show the bottom, or manually, in which
the user controls the location of the Zoom range.
Automatic Zoom is especially helpful when looking
for structure or bottom detail. The Automatic
Zoom keeps the bottom in view even in quickly changing terrain, but is most
useful in flatter areas without considerable depth variation. Manual Zoom pro-
vides detailed information of any area from the surface to the bottom. In man-
ual Zoom, the Zoom range does not move as the terrain changes.
When the range is shown in the menu, the upper number represents the top of
the current Zoom range. The lower number represents the bottom of the Zoom
range. Use the UP and DOWN ARROW buttons to move this range. The upper
number can never be less than 0 (the surface of the water), and the lower num-
ber can never be greater than the active depth range. The difference between
the two numbers (the Zoom range) is preset and determined by the active depth
range.
Once manual Zoom is selected, the display appears the same as in Auto Zoom,
but the zoom range does not change automatically.
To disable Zoom, press the MENU button until the Zoom menu is on-screen. Use
the UP ARROW to highlight Off, and let the
menu time out.
When the unit is powered off, the Zoom
menu returns to Zoom Off.
Depth Alarm. The Pro Craft unit contains
an audible alarm to warn you of shallow
water depths. The alarm is adjustable to
depths of 2' (.6m) to 99' (30m). When the
alarm is enabled, an audible alarm sounds if
the water beneath the boat is equal to or
less than the selected alarm depth. The

14
alarm sounds continuously for about five
seconds, and then intermittently to remind
you that you are still in shallow water.
Fish Alarm. The Fish Alarm alerts you to the
presence of fish, or other targets not con-
nected to the bottom. The Fish Alarm has
three different settings that correspond to
the three different size fish symbols shown
on-screen.
The default setting is “OFF.”With the
“Large fish only”setting, the Pro Craft unit
alarms on only those targets that are repre-
sented by the large fish symbols. The Pro
Craft unit can be set to alarm on only large
and medium fish, or set to alarm on all fish.
Once the Fish Alarm is enabled, the Pro
Craft unit emits an audible beep when the
selected size fish symbol appears on-screen.
The sound is slightly different for each of
the three fish symbol sizes, so with practice,
it is possible to distinguish the size of the
detected fish without looking
at the unit.
Triplog. Triplog provides a
running log of information
based on input from the Temp/Speed sensor.
Since Triplog requires information
from the Temp/Speed sensor to oper-
ate, if this sensor is not detected by
the Pro Craft unit, the Triplog menu
will not appear as an option.

Triplog provides seven pieces of informa-
tion: the current digital depth, water sur-
face temperature, current boat speed, the
distance traveled since the Pro Craft unit
was powered up or reset, the average
speed, the total time elapsed since power-
up or reset, and the input voltage from
your boat’s electrical system.
The time, speed and distance calculations
are useful for tracking your progress on a
trip. The input voltage is useful for deter-
mining the condition of the charging sys-
tem of the boat. When used in a portable
application or whenever the Pro Craft unit
is operated from a battery source, the voltage number
can be used to determine battery life. The Pro Craft
unit will operate at voltages from 10 to 20 VDC. Volt-
ages in excess of 20 or less than 10 VDC cause the unit
to power off.
Options. The Options Menu is a series of linked menu
functions used initially to set your preferences. Once
your preferences are selected, it is unlikely these func-
tions need to be accessed during the normal opera-
tion of the product.
The Options menu works differently than other
menu functions in that all of the options must be
cycled through in order to return to normal operation. There are twelve.
Option menus: Contrast, Display Speed, Bottom Black, Fish ID, Numeral
Size, Diagnostic, Units, Speed Offset, Depth Off-
set, and Reset.
Contrast. The Contrast function allows the user
to control the level of contrast of the LCD display.
The Pro Craft unit will automatically adjust the
display contrast to compensate for changing
USING THE PRO CRAFT UNIT
MENU FUNCTIONS

16
ambient temperatures; however, some situations may occur where manu-
al adjustment will provide a higher level of contrast.
Eleven contrast settings, +5 to -5, are possible. The display contrast will
change as the adjustment is made so the optimum level of contrast can be
achieved. Use the ARROW buttons to highlight the desired selection. The
Pro Craft unit will reset to the factory setting when the unit is powered off.
Display Speed. Display Speed controls
the rate at which the graphic information
moves across the display. There are 5 pos-
sible speeds; the fastest rate (5) is the fac-
tory setting. Keep in mind that the closer
the update rate matches your boat speed,
the more accurate is the graphic depiction
of the terrain beneath your boat.
Use the UP and DOWN ARROWS to select the desired update rate. The Dis-
play Speed setting is remembered when the unit is powered off.
Bottom Black. There are two selections
available: OFF and ON. The factory setting is
OFF. With this setting, the Pro Craft unit dis-
plays the
bottom
using
Structure
ID. This
allows you to determine the texture and
relative hardness of the bottom. Select-
ing Bottom Black “ON”causes the unit
to blacken in the display below the bot-
tom. This gives the user easiest recogni-
tion of the bottom location, even from a
great distance.
The Pro Craft unit remembers the Bot-
tom Black setting when powered off.

Fish ID. There are three selections available: OFF, ID+ ON, and ADJUST. The fac-
tory setting is ID+ ON. With Fish ID OFF, sonar returns are displayed as “raw”
information. There is no interpretation made by the unit. Selecting ID OFF also
disables the fish alarm.
ID+ ON enables the Pro Craft unit to interpret the raw sonar data and,
using a variety of techniques, depict appropriate target returns as one of
three different size fish symbols. Further identification shows whether the
fish is in the wide or narrow beam. The Pro Craft unit also displays the
depth beneath the surface with the corresponding fish symbol.
Selecting Adjust and making incremental changes enhances the fishfinder’s
ability to identify sonar returns as fish symbols.
Increasing the value to a number greater than
zero shows more fish symbols on-screen. In
this case smaller sonar returns will be depicted
as fish symbols. This is useful for identifying
many smaller sonar returns (such as baitfish)
as fish symbols.
Decreasing the value to a number less than zero
shows fewer fish symbols on-screen. In this case
smaller sonar returns are disregarded. This is
useful for eliminating many small sonar returns
when seeking larger species of fish.
The Pro Craft unit remembers this selection
even when the unit is powered off.
Numeral Size. Two options are available: BIG
and SMALL. The factory setting is BIG. With
this setting, the

for the graphics area. Hence, the small numerals option. With small numer-
als selected, a greater amount of the display area is available for the graph-
ic view. This effectively increases the display resolution of the unit.
Numeral Size settings are remembered when powered off.
Diagnostic. Two options are available: HIDE and
SHOW. The factory setting is HIDE. Selecting SHOW
brings up the Diagnostic screen. See the Using Diag-
nostic section for more information.
Units. The Units function allows the user to select
the units of measurement for the depth and speed
readout. FEET/MPH (feet/statute miles per hour) and FEET/KTS (feet/nautical
miles per hour), are available.The Pro Craft unit remembers this selection even
when the unit is powered off.
Speed Offset. The Speed Offset option allows
the user to compensate for differences in hull
design, and its effect on the accuracy of the
speed measurement.
If there is a discrepancy between the indicated
speed and another speed measurement device
on the boat, the speed measurement can be var-
ied to improve accuracy. Remember, the speed
paddle wheel measures speed through the water,
not speed over ground.
Speed offset is remembered after power is disconnected.
Depth Offset. The Depth Offset allows the user
to select the point on the boat from which the
depth measurement is made. Selecting a positive
value adds distance to the measurement. If the
transducer is mounted 3 feet beneath the water-
line, a positive 3 will show the correct depth from
the surface of the water.
