Sonar Views

Sonar View presents a historical log of the stored

sonar returns. 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. A Digital Depth Readout

is displayed in the upper left corner. A scale with

Upper and Lower Depth Range readouts appears

along the right edge of the Sonar View. The scale

indicates the distance from the surface of the water

to a depth range sufficient to show the bottom.

Depth Range is automatically selected to keep the bottom visible on screen, although

it can be manually-adjusted by the user as well (see Sonar Settings - X-Press

Menu).

Up to five additional Digital Readouts display information from optional-purchase

accessories such as Water Temperature, Trolling Speed, WeatherSense

Barometric

Pressure and more. These information boxes can be customized to show only the

information desired (see Advanced User Mode - Select Readouts).

A Real Time Sonar (RTS®) window appears on the

right side of the display. 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. In the RTS Window, sonar

returns are shown in shades of gray. The most

intense returns are shown as a solid black band

that indicates the bottom. The thickness of the

bottom band indicates bottom type. Hard bottoms

appear thinner and mostly black; softer bottoms are thicker and may appear with

many gray tones. Above the bottom band, less intense sonar returns shown as

varying shades of gray indicate the sonar returns from fish or structure. The RTS

Window can be turned on or off (see Sonar Settings - Main Menu Sonar Tab).

As the boat moves, the Matrix unit charts the

changes in depth on the display to create a

profile of the Bottom Contour. The default

presentation highlights the bottom profile with

a Structure ID® feature and gray tones. From the

appearance of the gray tones in the bottom

contour, the type of bottom can be determined.

A Hard Bottom such as compacted sediment or

flat rock appears as a thinner dark 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. Rocky Bottoms have a broken, random

appearance. In shallower water, a Second Sonar Return may appear as a bottom

contour below the main bottom at twice the depth. The second return occurs

when the sonar signal bounces between the bottom and the surface of the

water and back again. Experienced anglers 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. The Matrix

unit is capable of revealing layers of water with different temperatures called

thermoclines. Thermoclines 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.

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 graphed on

the display. Boat speed, chart

speed, and the position of the fish within the

sonar beam greatly affect the shape of the arch.

For optimum fish arching, it is important to

mount the transducer so that it is pointing

straight down. The Matrix unit has an advanced

Selective Fish ID+

option that analyzes the sonar return to determine if the

sonar return may contain a fish (see Sonar Settings - Main Menu Sonar Tab).

When a target is detected, a Fish ID+

symbol appears on the display with the

depth. The size of the symbol indicates the intensity of the sonar return. Targets

detected in the narrow beam directly under the boat appear as Shaded Fish

Symbols. Targets detected in the wide beam around the boat appear as Hollow

Fish Symbols. The Matrix unit will clearly show schools of Bait Fish as "clouds" of

different shapes and sizes, depending on the number of fish and boat speed.

Sonar Zoom View increases the display

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 full range view on the right and the

zoomed view on the left. 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 Settings - X-Press Menu). Upper and Lower

Zoom Depth Range numbers indicate the depth

of the water which is being viewed.

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 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 (see

System Settings - Main Menu Setup Tab).

How Sonar Works

Sonar technology is based on sound waves. The Matrix

Fishing System uses

sonar to locate and define structure, bottom contour and composition, as well

as calibrate digital depth directly below the transducer.

Your Matrix unit 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.

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 ¼of a second. It is unlikely that your boat

can "outrun" this sonar signal.

DualBeamPLUS™ Sonar

Your Matrix 25 uses a dual frequency 200/83 kHz

DualBeamPLUS sonar system with a wide (60°) area of

coverage. DualBeamPLUS is optimized to show the

greatest bottom definition with a narrow (20°) beam, and

the fish and structure location with a wide (60°) beam.

DualBeamPLUS is ideal for a wide range of conditions - from shallow to very

deep water in both fresh and salt water. Depth capability is affected by such

factors as boat speed, wave action, bottom hardness, water conditions and

transducer installation. All sonar units typically read to deeper depths in fresh

water than in salt water. Your Matrix transducer also comes with a

temperature sensor included!

Powering Up the Unit

Turn on the Matrix unit by momentarily pressing the POWER key. A startup

screen is then displayed until the Matrix unit begins sonar operation. While

the startup screen is displayed, you may press the MENU key for the other

options listed below. If no key is pressed, the Matrix will begin Normal or

Simulator operation, depending on the presence or absence of a transducer.

The following operating states are available:

• Normal – Use for on the water operation with transducer connected.

• Simulator – Use to learn the features and functions of the Matrix unit.

Simulates on the water operation.

• System Status – Use to view system connections and conduct a unit

self-test.

• PC Connect – Use when upgrading Matrix internal software with a PC and

PC Connect cable.

The Matrix unit uses advanced transducer detection methods to determine if

a transducer is connected. If the transducer is not connected or is damaged,

the unit will select the Simulator state automatically at startup. If a

functioning transducer is connected, the unit will select the Normal operating

state automatically and the unit can be used on the water.

Note: When operating in Simulator state with a transducer connected, Menu

setting changes are saved to memory. If a transducer is not connected, changes

will not be saved and Menu settings will revert to factory defaults every

few minutes.

Sonar Settings - X-PressTM Menu

The X-Press menu represents the settings most frequently-

used to optimize the sonar performance of the Matrix unit.

Press the MENU key once while in any of the Sonar Views,

including Big Digits, to access the following X-Press menu

settings quickly:

Sensitivity provides advanced control over the sonar receiver.

The Matrix unit optimizes Sensitivity based on depth and

water conditions automatically; however, you also may change it manually to match

your preferences or water conditions. Increasing the sensitivity shows more sonar

returns from small bait fish and suspended debris in the water; however, the display

may become too cluttered in some water conditions. When operating in very clear

water or greater depths, increased sensitivity shows fainter 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.

Beam Select - Selects the sonar beam used in the Sonar Views. When 200 kHz is

selected, the sonar returns and Fish ID+ from the 200 kHz beam are displayed

providing greater bottom detail (typically from 2 feet to 800 feet) at any boat

speed. Using 83 kHz, the sonar returns and Fish ID+ from the 83 kHz beam are

displayed, providing greater depth capability and showing more targets in its

wider beam. The 83 kHz beam is not recommended for use when the boat is

traveling at greater than trolling speeds. When Both is selected, the unit blends

the sonar information from both beams together on the display to provide the

best sonar image and Fish ID+.

Lower Range adjusts the lower depth range to a specific depth for the Sonar

and Big Digits Views. Automatic is the default setting. Selecting a specific

setting locks the depth range into manual mode. Advanced anglers use both

Upper and Lower Range together to view a specific depth range manually when

looking for fish or bottom structure. The Upper Range menu choice is available

when User Mode is set to Advanced (see Advanced User Mode). will be

displayed when you start manually adjusting the Lower Range to indicate that

you’re in Manual mode.

Chart Speed determines the speed at which the bottom 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

bottom moves across the display quickly. The highest setting is an ultrafast mode

that provides the highest chart speed possible by slowing down other system

functions. A slower speed keeps the information on the display longer, but the

bottom and fish detail becomes 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.

Zoom Level sets the magnification level for the Sonar Zoom View.

Sonar Settings – Main Menu Sonar Tab

Less frequently-adjusted menus are grouped into the Main

Menu System. Press the MENU key twice to access the Main

Menu System.

Fish ID+

uses advanced signal processing to interpret sonar

returns and display a Fish Symbol when very selective

requirements are met. A number above the fish icon indicates

the depth of the fish. Three different fish size icons show the

intensity of the sonar return, and provide an indicator of

relative fish size. When Fish ID+ is turned off, the Matrix shows only the unprocessed

sonar returns on the display. These returns will often result in "arches" forming on

the display, indicating potential targets.

Fish Sensitivity adjusts the thresholds of the fish detection algorithms, thus

enhancing your unit’s ability to identify sonar returns as fish icons. Selecting a

higher setting allows fainter returns to be displayed as fish icons and will increase

the number of fish icons that appear on the display. This is useful for identifying

smaller fish species or baitfish. Selecting a lower setting displays fewer fish icons

from faint sonar returns. This is helpful when seeking larger species of fish.

Bottom View selects the method to display bottom and structure on the display.

Structure ID® presents the graphical representation of the bottom and structure

sonar returns using only grayscale to indicate the signal strength. WhiteLine®

highlights the strongest sonar returns from the bottom to make a distinctive

outline of the bottom contour, structure and fish. Bottom Black displays all

pixels below the bottom contour as black, regardless of signal strength.

RTS Window turns the RTS window on or off in the Sonar View.

Alarm Settings - Main Menu Alarm Tab

Various audible alarms can be triggered in the Matrix unit

based on these menu settings. When an alarm is triggered,

it can be silenced by pressing the EXIT key.

Depth Alarm sounds when the digital depth becomes

equal to or less than the menu setting.

Fish Alarm sounds when the Fish ID+ feature displays fish

symbols that correspond to the menu setting.

Low Battery Alarm sounds when the input battery voltage is equal to or less than

the menu setting.

Alarm Tone selects the pitch of the alarm sound to improve audibility. As the

menu is adjusted a brief tone will be produced so that you can select the tone

that you can hear best.

Advanced User Mode

Preset menu modes are available to suit your personal Angler Profile - whether

you're a Normal User or Advanced User. These Angler Profile Presets

provide an

Advanced Mode for users who desire the highest level of control over the

product, and Normal Mode for users who desire the greatest simplicity and

fewest choices.

Choose User Mode from the Setup Tab and change the selection to Advanced to

access advanced features. A range of additional options will be displayed in the

menu system. Any changes made under the Advanced mode will remain in effect

if the unit is returned to Normal mode.

Sonar X-Press Menu - Advanced User Mode

Upper Range Adjusts the Upper Depth Range to a specific depth for the Sonar and Big

Digits Views. (0 to 1190 feet, Default: 0)

83 kHz Sensitivity Adjusts the sensitivity applied to the 83kHz beam to be higher or lower

than the overall sensitivity settting. (-10 to +10, Default=0)

Sonar Menu - Advanced User Mode

Surface Clutter Adjusts the filter that removes surface clutter noise caused by algae and

aeration. The lower the setting, the less surface clutter will be displayed.

(Low=1, High=10, Default=Low)

Noise Filter Adjusts the sonar Noise Filter to limit interference from sources such as

your boat engine, turbulence, or other sonar devices for best display

performance. (Off, Low, Medium, High, Default=Low)

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 unit’s ability to find the bottom.

Water Type Configures unit for type of water conditions. (Salt, Fresh, Default=Fresh)

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 can affect the accuracy of deep water

depth readings.

Max Depth Adjusts the maximum depth of unit operation.

(Auto, 10 to 1200 feet, Default=Auto)

Note: The performance of your unit can be tuned to the maximum depth you

will be fishing in by setting this menu choice. When a maximum depth is set,

the unit will not attempt to acquire sonar data below that depth, thus

increasing overall performance. When the Max Depth is set to Auto, the unit

will acquire bottom readings as needed (within the capacity of the unit).
