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 Barometer and Temp/Speed View. The scale indicates the distance from the surface of the water to a depth range sufficient to show the accessories are optional. Additional purchase required. 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). MultiBeam Sonar View presents sonar information from the left and right 90° 455 kHz beams and the 200 kHz down looking beam. In this view, the top portion of the display contains a history of sonar returns from the 200 kHz down looking beam. The bottom portion of the display contains a history of sonar returns from the 455 kHz right and left looking beams. New information appears at the top, and scrolls down the display. The sonar information from the side looking beams reveals bottom contour, structure and fish similar to the down looking beam, but the area covered is to the left and right of the information shown from the down looking beam, so you actually see more of the bottom. The displayed range of the left and right beams automatically follows that of the down beam to a maximum limit of 160 feet. With some practice in viewing the left and right beam information, you will be able to extract more information about the bottom than if you were viewing information solely from the down looking beam. The Understanding MultiBeam Sonar illustration will help you interpret information displayed by the left and right sonar beams. The left and right beams are only used in the MultiBeam Sonar View. 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(s). 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 Temp/Speed Accessory is optional. 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 Temp/Speed Accessory is optional. 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+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 Zoom Preview Box shows where the zoomed view is in relation to the full 83kHz Sonar Zoom View shown with Structure ID® on 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-tosee 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 Big Digits View shown with Settings - Main Menu Setup Tab).

WARNING! 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 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 X-Press menu. The following menu choices are view-dependent; only menu choices that apply to a specific view will be displayed: 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 83/200 kHz is selected, the unit blends the sonar information from both beams together on the display to provide the best sonar image and Fish ID+. Beam Select is not available in MultiBeam View because only the 200 kHz and 455 kHz beams present information in this view. 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. M 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. Chart Speed is not available in MultiBeam View. Zoom Level sets the magnification level for the Sonar Zoom View. 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 PresetsTM 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. Thank you for choosing Humminbird®, America's#1 name in fishfinders.
