The 700 SeriesTM Fishing System uses sonar to locate and define structure, bottom contour and composition, as well as depth directly below the transducer. Your 700 SeriesTM 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 1/4 of a second. It is unlikely that your boat can "outrun" this sonar signal. SONAR is an acronym for SOund and NAvigation Ranging. Sonar utilizes precision sound pulses or "pings" which are emitted into the water in a teardrop-shaped beam. The sound pulses "echo" back from objects in the water such as the bottom, fish and other submerged objects. The returned echoes are displayed on the LCD screen. Each time a new echo is received, the old echoes are moved across the LCD, creating a scrolling effect. When all the echoes are viewed side by side, an easy to interpret "graph" of the bottom, fish and structure appears. 1 531524-1_A - 717 & 727 Man_Eng.qxp 9/30/2006 7:23 PM Page 7 The sound pulses are transmitted at various frequencies depending on the application. Very high frequencies (455 kHz) are used for greatest definition but the operating depth is limited. High frequencies (200 kHz) are commonly used on consumer sonar and provide a good balance between depth performance and resolution. Low frequencies (83 kHz) are typically used to achieve greater depth capability. The power output is the amount of energy generated by the sonar transmitter. It is commonly measured using two methods: · Root Mean Square (RMS) measures power output over the entire transmit cycle. · Peak to Peak measures power output at the highest points. The benefits of increased power output are the ability to detect smaller targets at greater distances, ability to overcome noise, better high speed performance and enhanced depth capability. 2 531524-1_A - 717 & 727 Man_Eng.qxp 9/30/2006 7:23 PM Page 8 DualBeam PLUSTM Sonar Your 700 SeriesTM Fishing System uses a 200/83 kHz DualBeam PLUSTM sonar system with a wide (60°) area of coverage. DualBeam PLUSTM sonar has a narrowly focused 20° center beam, surrounded by a second beam of 60°, expanding your coverage to an area equal to your depth. In 20 feet of water, the wider beam covers an area 20 feet wide. The 20° center beam is focused on the bottom, to show you structure, weeds and cover. The 60° wide beam is hunting for fish in the wide coverage area. DualBeam PLUSTM sonar returns can be blended together, viewed separately or compared side-by-side. DualBeam PLUSTM 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. 3 531524-1_A - 717 & 727 Man_Eng.qxp 9/30/2006 7:23 PM Page 9 QuadraBeam PLUSTM Sonar (with optional-purchase QuadraBeam PLUSTM transducer) Your 700 SeriesTM Fishing System also supports QuadraBeam PLUSTM sonar with the purchase of an additional QuadraBeam PLUSTM transducer. QuadraBeam PLUSTM sonar provides an extremely wide 90° area of coverage. QuadraBeam PLUSTM starts with two fan-shaped 35° 455 kHz Side Structure locating sonar beams to spot fish, bait and structure to the left and right of the boat over an area of the bottom that's always equal to twice your depth. For a detailed view below the boat, QuadraBeam PLUSTM uses DualBeam PLUSTM technology, with precision 20° and wide 60° beams. QuadraBeam PLUSTM finds more fish faster, and can even tell you where to put your bait by showing if fish are to the left, right or directly beneath your boat. 4 531524-1_A - 717 & 727 Man_Eng.qxp 9/30/2006 7:23 PM Page 10 WideSide® Sonar (with optional-purchase WideSide® transducer) Your 700 SeriesTM Fishing System also supports WideSide® sonar with the purchase of an additional WideSide® transducer. The WideSide® transducer is a specialized "sidelooking" transducer that is extremely useful for bank fishing or looking for bait fish in open water. The WideSide® transducer uses three different sonar elements that transmit signals to the left, right and straight down from your boat. The downward beam is 200 kHz with a 24° area of coverage. This beam maintains a continuous digital depth readout from the bottom directly beneath your boat. The side beams are 455 kHz with a 16° area of coverage. The side-looking elements can be used independently, or together to locate targets near the surface of the water on either side of your boat. 5 531524-1_A - 717 & 727 Man_Eng.qxp 9/30/2006 7:23 PM Page 11 Universal Sonar 2 Your 700 SeriesTM Fishing System supports Universal Sonar 2, a state-of-theart, integrated and protected transducer that is built into the lower unit of Minnkota trolling motors. With Universal Sonar 2, all wiring is concealed inside the indestructible composite shaft--out of sight and out of harm's way, with no clamps, ties, or exposed wires. Universal Sonar 2 features new temperature sensing and the performance of DualBeam PLUSTM technology (available with all Humminbird® DualBeam PLUSTM models). An expanded view and greater bottom detail gives you a totally new perspective of the water below, along with optimal sonar performance to help you find fish. 6 531524-1_A - 717 & 727 Man_Eng.qxp 9/30/2006 7:23 PM Page 12 What's On the Display The 700 SeriesTM Fishing System can display a variety of useful information 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 700 SeriesTM can display the speed of the boat, and can keep a Triplog of nautical or statute miles traveled.

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). Six Digital Readouts display information from optional-purchase accessories. These information boxes can be customized to show only the information desired (see Setup Menu Tab, Select Readouts). NOTE: If the Depth number is flashing, it means that the unit is having trouble locating the bottom. This usually happens if the water is too deep, the transducer is out of the water, the boat is moving too fast, or for any other reason that the unit can't accurately receive continuous data.

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. 11 531524-1_A - 717 & 727 Man_Eng.qxp 9/30/2006 7:23 PM Page 17 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, Structure ID®, 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. Freeze Frame and Cursor Freeze Frame - Pressing any arrow on the 4-WAY Cursor Control key will freeze the screen 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 available in Sonar, Sonar Zoom and 200/83 kHz Split Sonar Views. 12 531524-1_A - 717 & 727 Man_Eng.qxp 9/30/2006 7:23 PM Page 18 Bottom Presentation As the boat moves, the unit charts the changes in depth on the display to create a profile of the Bottom Contour. The type of bottom can be determined from the return charted on the display. A Hard Bottom such as compacted sediment or flat rock appears as a thinner line across the display. A Soft Bottom such as mud or sand appears as a thicker line across the display. Rocky Bottoms have a broken, random appearance. Bottom Contour Profile with RTS® Window. Temp/Speed Accessory is optional. Hard Bottom Soft Bottom Rocky Bottom The sonar returns from the bottom, structure and fish can be represented as either Inverse (default), WhiteLine®, Structure ID®, or Bottom Black. See Sonar X-PressTM Menu: Bottom View for details on how to set the bottom view. 13 531524-1_A - 717 & 727 Man_Eng.qxp 9/30/2006 7:23 PM Page 19 Inverse is a method where weak returns are shown with dark pixels and strong returns with lighter pixels. This has the benefit of ensuring that weak signals will be clearly visible on the display. 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. 14 531524-1_A - 717 & 727 Man_Eng.qxp 9/30/2006 7:23 PM Page 20 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. 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. 15 531524-1_A - 717 & 727 Man_Eng.qxp 9/30/2006 7:23 PM Page 21 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.

Increasing the sensitivity shows more sonar returns from small baitfish and suspended debris in the water; however, the display may become too cluttered. When operating in very clear water or greater depths, increased sensitivity shows weaker 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. NOTE: The Sensitivity setting is a global setting and will adjust the sensitivity of all sonar frequencies, as compared to specific sensitivity adjustments (such as 83 kHz Sensitivity, 455 kHz Balance or Wideside Sensitivity) which allow you to adjust the level of sensitivity for one specific beam at a time.

The Upper Range menu choice is available when User Mode is set to Advanced (see Setup Menu Tab: User Mode) and can only be accessed from the Sonar, Split Sonar, Big Digits and Circular Flasher views. Upper Range is often used with Lower Range. For example, if you are only interested in the area between 20 and 50 feet deep, you should set the Upper Depth Range to 20 and the Lower Depth Range to 50. The Sonar View will then show the 30 foot area between 20 and 50, and will not show the surface or the bottom (assuming the bottom is deeper than 50 feet), and will show greater detail for that area between 20 and 50 feet. NOTE: A minimum distance of 10 feet will be maintained between the Upper and Lower Range regardless of the manual settings entered. To adjust the Upper Range: 1.
