NOTE: Your 700 Series does not support Navionics Classic Charts, only Navionics Gold, HotMaps, and HotMaps Premium.
Your unit also comes with a built-in Uni-Map with a more detailed map of North America (Domestic models) or a more detailed map of Europe and Southeast Asia, including Australia and New Zealand (International models). Your 700 Series uses the GPS Receiver to determine the position of the boat automatically, and uses the zoom level settings on a particular view to select the best chart to display. See Viewing Cartography for more information.
Multi-Media Card (MMC)/SD Slot
Your 700 Series Fishing System also has a multi-media card (MMC)/SD slot that is used to insert optional-purchase cards containing additional detailed maps. If you insert an Inserting an MMC/SD MMC/SD that contains a more detailed chart for into the Card Slot a particular location, your 700 Series Fishing System will retrieve that chart and display it automatically. Use the illustration to locate the position of the MMC/SD slot cover, remove the MMC/SD slot cover, then insert the MMC/SD into the slot. The label on the MMC/SD should face toward the right side of the unit. Press down on the card until it clicks into place, then replace the slot cover, making certain that the gasket is present and positioned correctly before re-installing the cover, then replace and tighten snugly - do NOT overtighten, as this will not improve water resistance, and may damage the cover.

Software Updates

Use the MMC/SD slot to update the software version of your control head. To update the software in your control head, plug in the appropriate MMC/SD card that contains a software update file; the unit will recognize it, will tell you what software version your control head is currently running, and will ask you if you want to update the software in the unit to match that on the MMC/SD card. You can obtain software updates from the www.humminbird.com website.

Whats On the Display

The 700 Series Fishing System can display a variety of useful information about
Depth - water depth; can be set to alarm when the water becomes too shallow. Cursor - available in Freeze Frame and can be positioned in the Sonar View to provide depth of a sonar return and bottom depth below the cursor. 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. Speed - if a Temp/Speed accessory or GPS Receiver is attached, the Fishing System can display the speed of the boat, and can keep a Triplog of nautical or statute miles traveled. Second Sonar Return - when the sonar signal bounces between the bottom and the surface of the water and back again. 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. Cursor Dialog Box - indicates cursor depth on the display and the depth of the bottom directly below the cursor. The Latitude and Longitude of the cursor position, the distance to travel to the cursor position and the bearing to the cursor position is shown with a GPS receiver. A waypoint can be marked at the cursor position for later retrieval and use with a GPS receiver.

Main Menu Tabs - Less frequently-adjusted menus are grouped into the Main Menu System. The Main Menu system is organized under the following tab headings to help you find a specific menu item quickly: Alarms, Sonar, Navigation, Chart, Setup, Views and Accessories. Press the MENU key twice for the Main Menu, then use the 4-WAY Cursor LEFT or RIGHT key to select a tab, and use the DOWN or UP key to select a specific menu item under that tab, then use the LEFT or RIGHT keys again to change a Main Menu System Normal User Mode menu setting. Press the EXIT key to move quickly to the top of the tab. A down arrow at the bottom of a menu means that you can scroll to additional menu choices using the DOWN Cursor key. A right or left arrow on a menu choice means that you can use the RIGHT or LEFT Cursor keys to make changes or to see more information.
NOTE: The Main Menu choices will vary depending on whether you are in Normal or Advanced User Mode.
User Mode (Normal or Advanced) - An Advanced Mode is provided for users who desire the highest level of control over the Fishing System and Normal Mode for users who desire greater simplicity and fewer menu choices. Additional Advanced menu choices will be displayed throughout the menu system when you navigate to specific menus while in Advanced Mode. Any changes made while in Advanced Mode will remain in effect after you switch back to Normal Mode. See Setup Menu Tab: User Mode for specific instructions on changing to Advanced User Mode.

Sensitivity

Sensitivity controls how much detail is shown on the display and will adjust the sensitivity of all sonar frequencies. 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.

Quad Layout

(with Optional-Purchase QuadraBeam PLUS Transducer, Side Beam View only)
Quad Layout selects the method used to represent the sonar information from the two side-looking beams plus the down-looking beam to be presented on the Side Beam View, and is only available when an optional-purchase QuadraBeam PLUS transducer is attached and the Side Beam View is active.

Feature Memory: Feature Memory is a Humminbird feature that retains the user's menu settings in permanent memory. Settings are retained even when the unit is powered off indefinitely. Fish Arch: A Fish Arch is the apparent "arch" that appears on the display when any object moves through the sonar cone. The arch results from a gradual decrease in distance to an object as it moves into the sonar cone. The distance to an object changes due to the conical shape of the sonar beam, which causes the distance to be greater at the edges of the beam than at the center of the beam. When this distance change is graphed on the display, an arch appears. Fish ID+: Fish ID+ is a Humminbird feature that uses advanced sonar processing algorithms to determine if a detected object is likely to be a fish. When the sonar signal from an object meets strict parameters, the unit draws a Fish Symbol (or icon) and the digital depth of the target. On DualBeam and DualBeam PLUS units, fish detected in the narrow center beam are shown as shaded symbols, and fish detected in the wider beam are shown as hollow symbols. Fish Symbol: A Fish Symbol is the graphic that is displayed on the screen when Fish ID+ determines that a sonar return is likely to be a fish. See Fish ID+. Freeze Frame: Freeze Frame is a Humminbird feature that pauses the sonar scrolling so that the image on screen can be studied with greater detail. See Instant Image Update. Frequency: Frequency is a measure of the number of sound wave cycles per second of a sound impulse transmitted underwater. A typical frequency for fishfinders is 200 kHz, which offers a good balance of performance under many conditions. Lower frequencies, such as 50 kHz, are capable of penetrating to greater depths, but with less resolution. Higher frequencies, such as 455 kHz, offer greater resolution, but are limited in depth performance. Humminbird uses a variety of frequencies that are optimized for specific applications. Grayscale: Grayscale is the use of varying shades of gray to represent the strength of the sonar signal on the display , and is a very intuitive method of presenting information. Traditionally, the strongest sonar signals are represented in black, and progressively weaker signals are represented in progressively lighter shades of gray. 145
Grayscale, Inverse: Inverse Grayscale is a Humminbird feature that reverses the correlation of sonar signal strength and the shade of gray typically used to represent it. The strongest sonar signals are represented by "white", and progressively weaker signals are represented in progressively darker shades of gray. While somewhat counter-intuitive, this method makes the sonar images crisper, and has the benefit of enhancing the apparent sensitivity because the weaker signals appear bolder. Inverse grayscale works well in very clear water. Debris-laden water often appears as a lot of clutter on the screen. Instant Image Update: Instant Image Update is a Humminbird feature that updates all the sonar information on the display when Sensitivity and a variety of sonar settings (Bottom View, Range, etc.) are modified. This differs from the traditional functionality that only updates the new sonar information collected after the setting change. Instant Image Update permits more accurate fine-tuning of the display because the user can see the results on the complete sonar graph. When combined with the Freeze Frame feature, the user can adjust and understand the effects of many different sonar settings quickly and easily. Maximum Depth Menu: The Maximum Depth Menu is a Humminbird feature that optimizes performance based on the maximum operational depth set by the user. Many Humminbird units can operate across a very broad depth range (up to 2500 feet) which causes the unit to "look" up to that full depth under some circumstances. Due to the speed of sound in water, this can result in less responsiveness because the unit has to wait for a longer period of time to receive the sonar signal. When the Maximum Depth menu is set to a lower value, the unit only looks up to the setting, which increases the responsiveness of the unit. This is an important feature for anyone operating in shallower depths! Noise: Noise is unintentional, external sound waves that interfere with the optimal operation of sonar. Noise appears as random "dots" on the display, and is caused by a variety of sources. Electrical noise (from trolling motors, bilge pumps, VHF radios) typically manifests as a consistent dot pattern. Electrical noise can be isolated by selectively turning on and off other electrical devices to determine the source. Often re-routing the power cable, or connecting to an alternative power supply (second battery) can help overcome electrical noise. Hydrodynamic noise (from propeller and/or hull cavitation) has a more random appearance and is generally related to boat speed, so that faster operation results in more noise. 146

new range, and the old sonar information would continue to scroll off the screen at the old range. Transducer: The transducer is part of the sonar system, which mounts on the boat and is in contact with the water, that converts the electrical energy from the transmitter into sound energy, and that forms the sonar beam in turn. Internally, the transducer consists of one or more piezo electric disks that expand by very minute amounts to create the sound wave. This element also works in reverse, converting the returned sound energy back into an electrical signal that the receiver interprets. Transducers are available for many specific mounting applications for the boat, such as a transom mount, trolling motor mount, etc. Humminbird offers many sophisticated transducers, often with multiple piezo electric elements designed to form specifically-shaped sonar beams, providing the angler with superior tools for finding and catching fish. See Transmitter and SONAR. Transmitter: The transmitter and receiver are matched parts of the sonar system that send (transmit) and listen to (receive) the sonar signals, and work in conjunction with the transducer. Humminbird transmitters have an extremely fast cycling design that can send signals up to 60 times per second, as well as produce the varying levels of power output needed for different depths and conditions. Additionally, the transmitter has the capability to create very precise sonar pulses needed for a high degree of target separation. Humminbird receivers are extremely sensitive, but within a narrow "bandwidth" to discriminate against noise from external sources. Additionally, the receiver offers a wide "dynamic range" which provides the ability to receive very strong signals alternating with very weak signals, without the strong signal overwhelming the weak signal. See Transducer and Noise. TripLog: TripLog is a Humminbird feature that provides an on-screen counter for Elapsed Time, Average Speed and Total Distance traveled, and requires a speed input to activate the feature. TripLog appears on the Big Digits View, and can be reset to zero through the TripLog menu. TrueArch: TrueArch is a Humminbird feature that provides true fish arches, not artificial arches or symbols. Humminbird units are capable of producing fish arches due to the wide 60 sonar beam of DualBeam PLUS, an extremely sensitive sonar receiver. See Fish Arch. 151
Viewing Angle: Viewing Angle is an attribute of an LCD that characterizes visibility of the display when viewing from off the central access, such as when standing to the side of the fishfinder. Wider viewing angles are better because the information remains visible even when viewing from the side. WhiteLine: WhiteLine is a Humminbird feature that highlights the strongest sonar return on the display using a very light gray band. This is preferred by some anglers who have grown accustomed to the feature on paper graph chart recorders. WideSide: WideSide is a Humminbird sonar configuration used in an optional transducer. WideSide uses three sonar beams pointing to the left, right and down. Beams pointing to the left and right are effective for spotting fish and structure near the surface or on the bank. The downlooking beam provides depth information directly below the boat. X-Press Menu: X-Press Menus are a Humminbird feature that make the most commonly-used menu selections available with one press of the MENU key. Items that appear on the X-Press Menu are related to the current view, and present the most logical choices for that view. Sonar View X-Press menus will differ from Chart View X-Press menus, etc. X-Press menus are one of the principal reasons that Humminbird products are easier to use. Zoom: Zoom is a feature that focuses in on a smaller area of the bottom to provide enhanced resolution. With enhanced resolution, the angler can more easily see fish hanging in structure or multiple fish hanging close together. Split screen zoom divides the display into the full range view on the right, and the zoomed view on the left. Humminbird offers One-Touch Zoom which allows the zoom feature to be easily accessed from the regular sonar view with just one key press, eliminating the need to use menus to access the feature. Zoom, Bottom Lock: Bottom Lock Zoom is a feature that focuses on a smaller area just above the bottom to provide enhanced resolution. Unlike regular zoom, it continuously graphs the bottom at a constant point on the display regardless of changes in depth. This "flattens" out the bottom contour, but is effective at showing fish on or near the bottom, and is preferred by many saltwater anglers.

GPS & Navigation Terms: Acquisition Time: The length of time that a GPS receiver typically takes to determine a position from at least three satellites. Humminbird GPS receivers provide very fast acquisition times (under one minute), permitting users to get out on the water faster. Alarm, Arrival: The audible alert that sounds when the boat is equal to or less than the alarm setting (25 feet 3000 feet) from the location of the destination waypoint. Alarm, Drift: Drift Alarm is an audible alert that sounds when the boat is equal to or over the alarm setting (25 feet 3000 feet) from the location where the alarm was turned on. Alarm, Off-Course: Off-Course Alarm is an audible alert that sounds when the boats distance from the intended Track, (Cross Track Error), is equal to or over the alarm setting (25 feet 3000 feet). See Track and Cross Track Error. Altitude: Altitude measures height above sea level. Altitude is a measurement that can be provided by GPS. Bearing (BRG): Bearing is the direction to a destination waypoint measured in degrees from North (i.e. 321, where 000 is North, 090 East, 180 is South, 270 is West). Chartplotter: Chartplotter describes a navigation device that shows Present Position on a Map, along with Tracks, Waypoints, and Routes. All Chartplotters are also considered Trackplotters. All Humminbird GPS Combo units are Chartplotters. See Trackplotter. Cold Start: Cold Start refers to the procedure that a GPS receiver must perform when it does not have historical information regarding its current location. This procedure typically lasts for several minutes, and may be experienced upon first power up of the receiver, or if the receiver has been moved a great distance. Course Over Ground (COG): Course Over Ground is the current direction the boat is traveling measured in degrees from North (i.e. 321, where 000 is North, 090 East, 180 is South, 270 is West). When the Course Over Ground is equal to Bearing, the boat is said to be On Course and will arrive at the destination in the most efficient manner. COG is often confused with Heading. See Heading. 153
Cross Track Error (XTE): Cross Track Error is the straight-line distance of the boat from the intended Track. XTE measures how far the boat is off course, and also triggers the Off Course Alarm. See Track. Differential GPS (DGPS): Differential GPS is a system to improve the position accuracy of the Department of Defense GPS through the use of secondary correction signals broadcast from ground stations around the coastal United States and on some inland waterways. These correction signals are provided by the USCG and received by an auxiliary Differential Beacon Receiver (DBR) that connects to the GPS receiver. The advent of WAAS has largely negated the need for the added expense of a DBR in the United States. Distance To Go: Distance To Go is the straight-line distance between Present Position and the Destination Waypoint. DTG and SOG (Speed Over Ground) are used to calculate Time To Go. See Time to Go and Speed Over Ground. Estimated Position Error (EPE): Estimated Position Error is a calculation that indicates the potential position inaccuracy the user may experience due to a variety of GPS factors which include satellite position in the sky, signal strength and others factors. Fix Type: Fix Type indicates whether the GPS receiver is providing 2D fix or 3D fix. A 2D fix requires only three satellites and provides only latitude and longitude. A 3D fix requires four or more satellites, and provides latitude, longitude and altitude. GPS: GPS is an acronym for Global Positioning System. GPS provides accurate position (latitude, longitude, altitude) information virtually anywhere on the earth through satellite technology and personal receivers on the ground. A series of geosynchronous satellites broadcast a unique signal toward the earth once per second. A GPS receiver, such as that included with many Humminbird products, receives the signals from these satellites and is able to determine position based on very slight differences in the time each signal is received and the receivers knowledge of the location of each of the satellites. Heading: Heading describes the direction the boat is pointing and is measured in degrees (i.e. 321, where 000 is North, 090 East, 180 is South, 270 is West). Due to wind and waves, the boat is often traveling in a slightly different direction than it is heading, and therefore Heading is often confused with Course Over Ground. See Course Over Ground. 154

Map Datum: A Map Datum refers to a particular survey of the earths surface that was referenced when creating a chart (i.e. WGS84). Since the earth is not flat, and not even consistently round, a mathematical model must be used to translate coordinates from the sphere of the earth to the flat surface of a chart. This mathematical model is the Map Datum. Historically, many different Map Datums have been used around the world to create maps; often a reference to the Map Datum can be found in the legend of a paper map. It is important to select the correct Map Datum setting in your fishfinder when comparing GPS position to a paper chart to avoid slight position inaccuracies. Almost all electronic charts use the WGS84 Map Datum and therefore, they do not require setting changes. MMC: MMC is an acronym for Multi Media Card. An MMC is a postage stampsized memory device used to store electronic data such a maps, waypoints, routes and other information. MMC is a very rugged format suitable for the marine environment, but it is not waterproof. The MMC is removable from Humminbird products, and can be used in a PC that is equipped with an appropriate card reader. MMC is the same format that many digital cameras use. See SD. North, Magnetic: North is the principle reference point of the compass (i.e. North is 000). Magnetic North relies on the earths magnetic field to align a metal pointer generally towards True North. However, due to local variations in the earths magnetic field around the globe, the difference between True North and Magnetic North can be greater than 10. See True North. North, True: North is the principle reference point of the compass (i.e. North is 000). True North uses the axis of the rotation of the earth as the reference for North and is constant for all points on the earth. Most GPS units default to True North as the setting. The GPS heading may vary from the boat compass heading because the compass uses Magnetic North. Humminbird GPS units provide the option of selecting True or Magnetic readouts by using the North Reference menu. See Magnetic North. Present Position: Present Position is the current location (latitude, longitude) determined by GPS. The Present Position is indicated on-screen by a directional boat icon if the boat is moving, or a round symbol if the boat is stationary. Route: A Route is series of waypoints linked together in a specific sequence to define a navigation path between two points, and saved in the fishfinders 155
