Introduction

How Sonar Works

Your Humminbird® Fishing System comes in several different configurations. See the following list of products, all of which are covered by this manual, to find your 800/900 Series™ configuration:
Humminbird® 858c HD Combo: Wide screen Fishing System with DualBeam PLUS™ Sonar and Chartplotting. GPS Receiver included.
Humminbird® 858c HD DI Combo: Wide screen Fishing System with Down Imaging™ Sonar, Traditional 2D Sonar, and Chartplotting. GPS Receiver included.
Humminbird® 858c HD XD Combo: Wide screen Fishing System with Xtreme Depth Sonar and Chartplotting. GPS Receiver included.
Humminbird® 898c HD SI Combo: Wide screen Fishing System with Side Imaging® Sonar, DualBeam PLUS™ Sonar, Down Imaging™ Sonar, and Chartplotting. GPS Receiver included.
Humminbird® 958c HD Combo:Ultra widescreen Fishing System with DualBeam PLUS™ Sonar and Chartplotting. GPS Receiver included.
Humminbird® 958c HD DI Combo: Ultra wide screen Fishing System with Down Imaging™ Sonar, Traditional 2D Sonar, and Chartplotting. GPS Receiver included.
Humminbird® 958c HD XD Combo: Ultra wide screen Fishing System with Xtreme Depth Sonar and Chartplotting. GPS Receiver included.
Humminbird® 998c HD SI Combo: Ultra wide screen Fishing System with Side Imaging® Sonar, DualBeam PLUS™ Sonar, Down Imaging™ Sonar, and Chartplotting. GPS Receiver included.
Sonar technology is based on sound waves. The Fishing System uses sonar to locate and define structure, bottom contour and composition, as well as depth directly below the transducer.
Your 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.
1
Introduction
When all the echoes are viewed side by side, an easy to interpret "graph" of the bottom, fish and structure appears.
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.

DualBeam PLUS™ Sonar

(DualBeam PLUS™ models only [858c HD, 898c HD SI, 958c HD, & 998c HD SI])
The 858c HD/958c HD Combo and 898c HD SI/998c HD SI Combo Fishing Systems use
a 200/83 kHz DualBeam PLUS™ sonar system with a wide (60°) area of coverage. DualBeam PLUS™ 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.
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.

Down Imaging™ Sonar

(Down Imaging™ models only [858c HD DI and 958c HD DI])
The 858c HD DI/958c HD DI Combo Fishing System uses Down Imaging™
technology. The Down Imaging™ transducer scans the water with razor­thin, high-definition beams. The beams are wide (side to side) but very thin front to back.
The Down Imaging™ beams can be operated at two frequencies: 455 kHz (75°) or 800 kHz (45°). Select 455 kHz for the best overall image quality and depth. Select 800 kHz for the sharpest image. See Down Imaging™ X-Press™ Menu: Imaging Frequency for more information.
The transducer also uses conical beams to provide data in traditional 2D format (see What’s on the Sonar View). Select 455 kHz for a narrowly focused 16° center beam, or select 200 kHz for a wider 25° beam (see Sonar Menu Tab: Beam Select).
Depth capability is affected by such factors as boat speed, wave action, bottom hardness, water conditions, and transducer installation.

Side Imaging
(Side Imaging® models only [898c HD SI and 998c HD SI only])
The 898c HD SI/998c HD SI Combo Fishing System uses Side Imaging®
sonar to provide a wide yet precise survey of a large area of water, including detailed bottom topography and fish­attracting structure orientation. The Side Imaging® transducer returns are processed into an image similar to an aerial photograph.
Typically, the Side Imaging® sonar can search an area that is 480 feet wide (240 to each side), with a typical depth performance of 150 feet when the Side Imaging® Sonar frequency is set for 455 kHz. The side beams can be operated at one of two frequencies: 455 kHz or 800 kHz. Selecting 800 kHz produces the sharpest image, but the search area to each side and the depth capability are limited as compared to the 455 kHz frequency. See What’s on the Side Imaging® Display and Understanding Side Imaging® for more information.
The Side Imaging® transducer also provides down imaging displays on the screen. See What's on the Down Imaging™ Display for more information.

Xtreme Depth Sonar

(Xtreme Depth Series™ models only [858c HD XD and 958c HD XD])
The 858c HD XD/958c HD XD Combo Fishing System uses the XD transducer to
provide extreme depth coverage with DualBeam PLUS™ technology.
The Xtreme Depth sonar beams can be operated at two frequencies: 50 kHz (74°) and 200 kHz (20°). The wide, 50 kHz beam transmits at a low frequency to provide greater depth coverage, up to 2500 ft (762 m). The narrow, 200 kHz center beam transmits at a high frequency to provide maximum detail at shallower depths.
The DualBeam PLUS™ technology allows you to view the sonar returns blended together, separately, or side-by-side (see Sonar Menu Tab: Beam Select and Views for more information).
Depth capability is affected by such factors as boat speed, wave action, bottom hardness, water conditions, and transducer installation.

QuadraBeam PLUS™ sonar provides a wide 90° area of coverage. QuadraBeam PLUS™ 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.

Universal Sonar 2

(compatible w/optional-purchase Minnkota trolling motors)
Your Fishing System supports Universal Sonar 2, a state-of-the-art, 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 PLUS™ technology (available with all Humminbird® DualBeam PLUS™ 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.
For a detailed view below the boat, QuadraBeam PLUS™ uses DualBeam PLUS™ technology, with precision 20° and wide 60° beams. QuadraBeam PLUS™ 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.

How GPS and Cartography Work

Your Fishing System also supports GPS (Global Positioning System) and chartplotting. It uses GPS and sonar to determine your position, display it on a grid, and provide detailed underwater information.
GPS uses a constellation of satellites that continually send radio signals to the earth. The GPS receiver on your boat receives signals from satellites that are visible to it. Based on time differences between each received signal, the GPS receiver determines its distance to each satellite. With distances known,the GPS receiver mathematically triangulates its own position. With 5 updates per second, the GPS receiver then calculates its velocity and bearing.
5
Introduction
GPS was originally intended for military use; however, civilians may also take advantage of its highly accurate position capabilities, typically within +/- 4.5 meters, depending on conditions. This means that 95% of the time, the GPS receiver will read a location within 4.5 meters of your actual position. Your GPS Receiver also uses information from WAAS (the Wide Area Augmentation System), EGNOS (the European Geostationary Navigation Overlay Service), and MSAS (the MTSAT Satellite Augmentation System) satellites if they are available in your area.
The following GPS functionality is currently supported by the Fishing System when it is connected to the included GPS receiver:
• View current position
• View current track (breadcrumb trail)
• View precision speed and heading from your GPS receiver
• Save tracks, waypoints, and routes
• Travel a route and navigate from one waypoint to the next.
See Chart View and SD Memory Card Slots: Add Maps to Your Fishing System for more information.

Understanding the Sonar Display

It is important to understand the significance of the 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.
The returned sonar echoes are displayed on the screen. As a new echo is received, the historical data scrolls left across the display.

Real Time Sonar (RTS™) Window

A Real Time Sonar (RTS™) Window appears on the right side of the display in the Sonar Views. 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 Tab: Real Time Sonar (RTS™) Window).
TheNarrow RTS Window™ indicates the sonar intensity through the use of colors. Redindicates a strong return and blue indicates a weak return. 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 isweakor strong. The depth of the sonar return is indicated by the vertical placement of the return on the display depth scale.

SwitchFire™

SwitchFire™ controls how the sonar returns are displayed in the Sonar Views. SwitchFire™ settings are available in the Sonar Menu Tab.
To see the maximum sonar information available within the transducer beam so more fish arches and better jig tracking are shown, choose Max Mode.
To see less clutter and more fish size accuracy interpreted from the transducer beam, choose Clear Mode. See Sonar Menu Tab: SwitchFire™ for more information.

What’s on the Side Imaging® Display

(Side Imaging® models only [898c HD SI and 998c HD SI])
Side Imaging® displays a number of easily recognizable features that allow for accurate interpretation of bottom contour and structure. For Side Imaging®, the bottom composition determines the intensity of the sonar return. For example, rock and gravel provide a clearer sonar return than mud and sand because of their relative density. Upward slopes that face the transducer reflect sonar better than downward slopes that face away from the transducer. You can find a number of easily recognizable features on the Side Imaging® display that allow for accurate interpretation of bottom contour and structure, including the following items:

Shadows - Result froma lack of reflectedsonar from a particular
9
area and can be more valuable for interpretation than the sonar reflected by the object itself. Use shadows to help you see the image in 3 dimensions, oriented in space. You can gain insight into the actual shape of an object, or the depth to which it has sunk into the bottom, through shadows on the display. Objects standing on the bottom cast a sonar shadow. The longer the shadow, the taller the object. Fish also cast shadows. You can use the shadow to interpret how close the fish is to the bottom.
Topography Changes- The light part of the screen shows where
10
the beam is hittinghard bottom or rising terrain. The dark part of the screen indicates soft bottom (sand, mud) or descending terrain.
