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 Barometer and Temp/Speed accessories are optional. indicates the distance from the surface of the water Additional purchase required. 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-PressTM Menu). Up to five additional Digital Readouts display information from optional-purchase accessories such as Water Temperature, Trolling Speed, WeatherSenseTM 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 Temp/Speed Accessory is optional. 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 Temp/Speed Accessory is optional. straight down. The Matrix unit has an advanced Selective Fish ID+TM 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+TM 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 kHz Sonar Zoom View shown Zoom Preview Box shows where the zoomed with Structure ID on 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).

This device should not be used as a navigational aid to prevent collision, grounding, boat damage, or personal injury. When the boat is moving, water depth may change too quickly to allow time for you to react. Always operate the boat at very slow speeds if you suspect shallow water or submerged objects.
Sonar Settings - X-PressTM Menu
The X-Press menu represents the settings most frequentlyused 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). M will be displayed when you start manually adjusting the Lower Range to indicate that youre 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.

How Sonar Works

Sonar technology is based on sound waves. The MatrixTM 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 of 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 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) 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 units ability to find the bottom.

Noise Filter

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.
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+TM 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 units 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.

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).

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 depth directly below the transducer. Your Matrix Fishing System 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 of a second. It is unlikely that your boat can "outrun" this sonar signal. Your Matrix Fishing System will either have Single Beam, DualBeam PLUS or QuadraBeam sonar. Find the correct sonar description that applies to your unit.

Single Beam Sonar

Your Matrix 10, 12 or 20 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.

DualBeam PLUS Sonar

Your Matrix 17 or 27 uses a 200/83 kHz DualBeam PLUS sonar system with a wide (60) area of coverage. DualBeam PLUS sonar returns can be blended together, viewed separately or compared side-by-side. DualBeam PLUS 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.

QuadraBeam Sonar

Your Matrix 37 Fishing System uses QuadraBeamTM sonar. QuadraBeamTM sonar provides an extremely wide 90 area of coverage. QuadraBeamTM starts with two kHz beams for a continuous 90 of uninterrupted side to side coverage to 160 feet. These Side Structure locating beams reveal fish and structure to the left and right of your boat near the bottom. For structure directly below your boat, QuadraBeamTM uses DualBeamPLUS technology.

Whats On the Display

The Matrix Fishing System can display a variety of useful information about the area
Depth - water depth; can be set to alarm when the water becomes too shallow. Speed - if a Temp/Speed accessory or GPS Receiver is attached, the Matrix can display the speed of the boat, and can keep a Triplog of nautical or statute miles traveled. Temperature - water surface temperature. Timer - elapsed time with Temp/Speed Accessory or GPS Receiver. Distance - distance traveled with Temp/Speed Accessory or GPS Receiver. Average Speed - average speed reading with Temp/Speed Accessory or GPS Receiver. Cursor - available in Freeze Frame and can depth of a sonar return and bottom depth

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. 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 the display, although you can adjust it manually as well (see Sonar X-PressTM Menu). Either five or six additional Digital Readouts (depending on your model) display information from optional-purchase accessories. These information boxes can be customized to show only the information desired (see Setup Menu Tab, Select Readouts).
Freeze Frame - Pressing any arrow on the 4-WAY Cursor Control key will freeze the screen in the Sonar View and a cursor will be displayed on the screen. The cursor can be positioned on the display using the 4-WAY Cursor Control key to determine the depth of any sonar return. The RTS Window continues to update in Freeze Frame. In addition, see the effects of menu setting changes with Instant Image Update. Pressing EXIT will exit Freeze Frame and the display will start to scroll. Freeze Frame is only available in the Sonar View.
Understanding Sonar History
It is important to understand the significance of the Matrix Fishing System 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.
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).
The Narrow RTS Window indicates the sonar intensity through the use of grayscale. The grayscale used matches the bottom view grayscale setting used in the sonar history window (i.e. Inverse, StructureID, WhiteLine, Bottom Black). The depth of the sonar return is indicated by the vertical placement of the return on the display depth scale. The Wide RTS Window indicates the sonar intensity through the use of a bar graph. The length of the 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. The Wide RTS Window does not make use of grayscale.

Sonar Zoom 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. 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-PressTM Menu: Zoom Level). Upper and Lower Zoom Depth Range numbers indicate the depth of the water which is being viewed. Digital depth is displayed in the upper left hand corner. The digital readouts in the Sonar Zoom View cannot be customized; therefore, information such as water temperature and voltage are unavailable in the Sonar Zoom View.

200/83 kHz Split Sonar View
(DualBeam PLUS and QuadraBeam Only) Split Sonar View displays sonar returns from the 83 kHz wide beam on the left side of the screen and displays sonar returns from the 200 kHz narrow beam on the right side of the screen. Depth is always displayed in the upper left hand corner. You can use the Split Sonar View to make side by side comparisons between the sonar returns from the 83 kHz wide beam and the 200 kHz narrow beam. The digital readouts in the Split Sonar View cannot be customized; therefore, information such as water temperature and voltage are unavailable in the Split Sonar View.

Depth Upper Depth Range

Big Digits 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.
Depth Timer shows the time elapsed since Triplog was last reset Distance is the distance traveled since the Triplog was last reset Voltage - the battery voltage. Speed Average Speed shows the speed since the Triplog was last reset

POWER/LIGHT Key

Structure ID represents weak returns as light pixels and strong returns as dark pixels. This has the benefit of ensuring that strong returns will be clearly visible on the display. The POWER/LIGHT key is used to turn the Matrix Fishing System on and off, and also to adjust the backlight and contrast of the display. Press the POWER/LIGHT key to turn the unit on. The Title screen is then displayed until the Fishing System begins sonar operation. Your Fishing System will start up with the backlight on and will automatically turn it off to conserve power. To turn the backlight on for night fishing, or to adjust the display contrast, press the POWER/LIGHT key to access the Light and Contrast menu. Use the 4-WAY Cursor key to select Light or Contrast and then use the LEFT or RIGHT Cursor key to change the settings. Press EXIT to exit the Light and Contrast 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 Fishing System should always be turned off using the POWER/LIGHT key. This will ensure that shutdown occurs properly and any menu settings will be saved.
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.

VIEW Key

Bottom Black displays all pixels below the bottom contour as black, regardless of signal strength. This has the benefit of providing a high contrast between the bottom and other sonar returns on the display. Any targets such as fish, structure and thermoclines will be shown using the Structure ID method. 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).

MENU Key

The MENU key is used to access the menu system. Start-Up Options Menu - Press the MENU key during the power up sequence to view the Start-Up Options menu. X-PressTM Menu - Press the MENU key once for the Sonar X-PressTM Menu. The X-PressTM Menu allows you to access frequently-used settings without having to navigate through the whole menu system. When the X-PressTM Menu is displayed, you can use the UP or DOWN Cursor keys to move to a particular menu choice. As soon as you alter a parameter (using the RIGHT or LEFT Cursor keys) the X-PressTM Menu will collapse temporarily, and the screen will update if it is affected by your menu setting change, allowing you to see the effects of your action immediately. Reactivate the X-PressTM Menu by using the UP or DOWN Cursor keys. Main Menu - Press the MENU key twice for the tabbed Main Menu System. The Main Menu System is organized under tabbed headings to help you find a specific menu item quickly: Alarms, Sonar, Setup and Accessories tabs are part of your tabbed Main Menu System. Use the LEFT or RIGHT 4-WAY Cursor Control key to select a tab; then use the DOWN or UP key to select the menu item, and the LEFT or RIGHT key to alter a menu setting.

EXIT Key

The EXIT key has multiple functions, depending on the situation: If an alarm is sounding, pressing EXIT will cancel the alarm. If a menu tab is selected, pressing EXIT will exit the menu mode and return to the view. If a menu is active, pressing EXIT will return to the previous level in the menu system. Pressing EXIT will cycle through the available views in reverse order. If Freeze Frame is active, pressing EXIT will return to a scrolling display.

4-WAY Cursor Control Key

Use the DOWN or UP arrow keys to select a menu choice from the menu list, then use the LEFT or RIGHT arrow keys to change a menu setting.
NOTE: Menu choices are implemented and saved immediately - no further action is required.
Press any arrow key to activate Freeze Frame while in the Sonar View and then use the 4-WAY Cursor Control Key to position the cursor on the display.

Accessory Bus

Use the Accessory Bus to expand the functionality of the Matrix Fishing System. Accessories plug directly into the Matrix Fishing System, enabling Advanced features such as WeatherSenseTM, GPS Functionality and the SmartCastTM Wireless Sonar Link. Additional menu tabs and menu choices will be added to the menu system automatically when an accessory is plugged into the unit. In addition, multiple accessories can be attached simultaneously. See Accessories Menu Tab and Matrix Fishing System Accessories in this manual, as well as your accessory's Operations Manual for additional details.
NOTE: Accessories to enable WeatherSenseTM, GPS Functionality and the SmartCastTM Wireless Sonar Link require separate purchases. You can visit our website at www.humminbird.com or contact our Customer Resource Center at 1-334-687-0503 for additional details.

The Menu System

The menu system is divided into easy-to-use menu modules. The main components of the menu system are: Start-Up Options Menu - Press the MENU key during the power up sequence to view the Start-Up Options menu. X-PressTM Menu - The X-PressTM Menu allows you to access the settings that are changed frequently without having to navigate through the whole menu system. Press the MENU key once to display the X-PressTM Menu. When you select a menu item from the X-PressTM Menu, the menu will collapse, leaving only the menu choice on the screen. Use the UP or DOWN Cursor keys to reactivate the X-PressTM Menu.

X-PressTM Menu

NOTE: The X-PressTM Menu choices will vary depending on which view is active when you press the MENU key, as well as whether you are in Normal or Advanced User Mode.

Powering Up the Unit

Turn on your Matrix Fishing System by pressing the POWER/LIGHT key. The Title screen is displayed until the Fishing System begins operation. Your Fishing System will begin Normal or Simulator operation, depending on the presence or absence of a transducer.

See the following paragraphs for more information about each of these choices.

Sonar Tab, Normal Mode

Normal Operation
Use Normal operation for on the water operation with a transducer connected. In addition, your Matrix Fishing System uses advanced transducer detection methods to determine if a transducer is connected. If a functioning transducer is connected, Normal operation will be selected automatically at power up and your Fishing System can be used on the water. Exit Normal operation by powering your Fishing System off.

Sonar Tab, Advanced Mode

Total Screen Update - when you change any menu settings that affect the Sonar View, the view will update immediately (i.e. you dont have to exit the menu to apply the change to the screen). For instance, by switching between "Inverse" and "Structure ID" from the X-PressTM Menu it is possible to alternate quickly between the two viewing methods.

Simulator

Use the Simulator to learn how to use your Matrix Fishing System 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 operation.
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 Fishing System 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 preconfigure your Matrix Fishing System for on the water operation. Any menu changes you make will be saved for later use.

System Status

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: Self Test Accessory Test.
System Status Self Test Screen

To change the Surface Clutter setting: To change the Depth Lines setting: 1. Make sure you are in Advanced User Mode, then highlight Depth Lines on the Sonar main menu. 2. Use the LEFT or RIGHT 4-WAY Cursor Control keys to turn the Depth Lines setting On or Off. (Off, On, Default = On) 1. Make sure you are in Advanced User Mode, then highlight Surface Clutter on the Sonar main menu. 2. Use the LEFT or RIGHT 4-WAY Cursor Control keys to change the Surface Clutter setting. (Low = 1 to High = 10, Default = 5)

Noise Filter

(Advanced) 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: 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 units ability to find the bottom.

Water Type

(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).
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.
To change the Noise Filter setting: 1. Make sure you are in Advanced User Mode, then highlight Noise Filter on the Sonar main menu. 2. Use the LEFT or RIGHT 4-WAY Cursor Control keys to change the Noise Filter setting. (Off, Low, Medium, High, Default = Low)
To change the Water Type setting: 1. Make sure you are in Advanced User Mode, then highlight Water Type on the Sonar main menu. 2. Use the LEFT or RIGHT 4-WAY Cursor Control keys to change the Water Type setting. (Fresh, Salt, Default = Fresh)

NOTE: When an alarm is triggered, you can silence it by pressing any key. The alarm will be silenced, and will not be triggered again until a new instance of the alarm condition is detected.

Alarms Menu

To change the Fish ID Alarm setting: 1. Highlight Fish ID Alarm on the Alarms main menu. 2. Use the LEFT or RIGHT 4-WAY Cursor Control keys to change the Fish ID Alarm setting. (Off, All, Large/Medium, Large, Default = Off)

All Large/Medium Large

Depth Alarm
Depth Alarm sounds when the depth becomes equal to or less than the menu setting. To change the Depth Alarm setting: 1. Highlight Depth Alarm on the Alarms main menu. 2. Use the LEFT or RIGHT 4-WAY Cursor Control keys to change the Depth Alarm setting. (OFF, 1 to 100 feet, or 0.5 to 30 meters [International Models Only], Default = OFF)

Low Battery Alarm

Low Battery Alarm sounds when the input battery voltage is equal to or less than the menu setting. The battery alarm will only sound for the battery that is connected to the Matrix Fishing System. The Low Battery Alarm should be set to warn you when the battery voltage drops below the safety margin that you have determined. For instance, if you are running a trolling motor (battery operated), you would want to set the Low Battery Alarm to sound before the battery voltage drops too low for it to be used to start your main, gasoline-powered engine. To change the Low Battery Alarm setting: 1. Highlight Low Battery Alarm on the Alarms main menu. 2. Use the LEFT or RIGHT 4-WAY Cursor Control keys to change the Low Battery Alarm setting. (Off, 8.5V - 13.5V, Default = Off)

Fish ID Alarm

Fish ID Alarm sounds when the Fishing System detects fish that correspond to the alarm setting. Fish ID Alarm will only sound if Fish ID+TM is on.
For example, if you've set the Fish ID Alarm to sound for Large fish only, the Fish ID alarm will sound when a large-sized fish is detected.

Alarm Tone

Alarm Tone selects the pitch of the alarm sound. A brief tone will be produced as you adjust the Alarm Tone so that you can select the tone that you can hear best. To change the Alarm Tone setting: 1. Highlight Alarm Tone on the Alarms main menu. 2. Use the LEFT or RIGHT 4-WAY Cursor Control keys to change the Alarm Tone setting. (High, Medium, Low, Default = Medium)

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. Low battery voltage may be affecting the power of signal transmission. Electrical noise from the boats engine may be interfering with sonar reception. See Finding the Cause of Noise for more information.
Finding the Cause of Noise
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: Possible Source of Noise

Other electronic devices

Matrix Fishing System Accessories
Accessories customize the Matrix Fishing System to your needs and enable you to stay on the edge of new technology. When an accessory is connected to the Matrix Fishing System, additional menus and readouts are added automatically to the Main Menu System. Accessories available today that are supported by your Fishing System include: Temperature/Speed: purchase and plug in the Temperature/Speed accessory to your Matrix control head to get real time speed and temperature readouts, as well as a valuable Triplog function.
NOTE: If an external Temperature/Speed (TS-W) or Temperature (TG-W) accessory is connected AND a transducer with temperature built in is connected at the same time, the TS-W or TG-W accessory will override the temperature which is built in to the transducer.

Isolation

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. To determine whether the boats 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. Turbulence created by the propeller can cause noise; make sure the transducer is mounted at least 15 (38 cm) from the propeller, and that the water flows smoothly over the face of the transducer at all times.

The boats engine

WeatherSense Fishing Condition Monitor: purchase and plug in the WeatherSense accessory to your Matrix Fishing System to obtain barometric pressure readouts and trend data in real time. GR4 GPS Receivers: purchase and connect the GR4 GPS Receiver to your Matrix Fishing System to access advanced FishingGPS, trackplotter and navigation capabilities built-in to your Fishing System. GPS Connection Cable: purchase the GPS Connection Cable in order to connect a handheld or other NMEA* GPS-compatible device that you may already own to your Matrix Fishing System. Wireless Sonar Link (WSL) purchase the Wireless Sonar Link (WSL) accessory to receive remote sonar signals from a SmartCastTM Remote Sonar Sensor (RSS).
