• Page 9: How Sonar Works

  How Sonar Works Sonar technology is based on sound waves. The 500 Series™ Fishfinder uses sonar to locate and define structure, bottom contour and composition, as well as depth directly below the transducer. Your 500 Series™ Fishfinder 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;…

• Page 10
  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.

• Page 11: Single Beam Sonar (550, 560)

  Single Beam Sonar (550, 560) The 550 Fishfinder and 560 Fishfinder use 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.

• Page 12: Dualbeam Sonar (570)

  DualBeam PLUS™ Sonar (561) The 561 Fishfinder uses 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.

• Page 13: Down Imaging™ Sonar

  Down Imaging™ Sonar (570 DI) The 570 DI Fishfinder uses Down Imaging™ technology. The Down Imaging™ transducer scans the water with razor-thin, high- definition beams. The beams are wide (side 45° 800kHz to side) but very thin front to back. 75°…

• Page 14: What’s On The Sonar Display

  What’s on the Sonar Display The 500 Series™ Fishfinder can display a variety of useful information about Depth — (water depth) can be set to alarm when the water becomes too shallow. Temperature — Water surface temperature. Timer — Elapsed time with Temp/Speed Accessory.

A thermocline typically appears as a continuous band of gray levels moving across the display at the same depth.

• Page 16: Understanding The Sonar Display

  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.

• Page 17: Switchfire

  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.

• Page 18: Bottom Presentation

  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.

  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.

  What’s on the Down Imaging™ Display Down Imaging™ uses its unique transducer and sonar technology to provide profiling beams produce the detailed sonar data that you see on the display. interpret the structure and bottom contour, including the following items: Depth — (water depth) can be set to alarm when the water becomes too shallow.

• Page 22: Understanding The Down Imaging™ Display

  Understanding the Down Imaging™ Display The images you see on the Down Imaging™ display are produced using sonar technology. Each time the unit pings, a strip of data representing all the echoes received by the transducer are put together on the display to form the image that you see.

• Page 23: Down Imaging™ Sensitivity

  Down Imaging™ Sensitivity Use Imaging Sensitivity to control how the sonar returns appear on the display. Increase the sensitivity to reveal weaker returns that may be of interest, especially in very clear water or greater depths. Decrease the Imaging Sensitivity to eliminate the clutter from the display that is sometimes present in murky or muddy water.

• Page 24: Views

  There are many views available on your Fishfinder. • Default View: When you first power up the 550, 560, 561, or 570 control head, Sonar View will be the default view. When you first power up the 570 DI control head, Down Imaging™ View will be the default view.

  Fish and other objects close to the bottom that fall within the dead zone will probably not be visible in the sonar beam. Precision sonar beams, such as the Humminbird® 20° beam, have a smaller dead zone than wider sonar beams.

  Noise appears as random “dots“ on the display and is caused by a variety of sources. Many Humminbird® products have a Noise Filter menu setting that allows the user to clear the screen of noise that is difficult to eliminate (also, see Troubleshooting).
• Page 82
  Many Humminbird® units operate at up to 40 times per second when in single frequency operation. Due to the limitation of the speed of sound in water, the update rate begins to slow as depth increases to deeper than 50 feet.

  Thermoclines Water layer(s) of distinctly different temperatures that create a sonar reflection due to the density of the differing water temperatures. Typically a thermocline will appear as a continuous band across the display at some distance above the bottom contour. Thermoclines are of interest to anglers because fish will suspend above or below the thermocline as they seek the optimum temperature and oxygen levels.
