Timer - Elapsed time with Speed accessory or GPS Receiver.
  • Page 31: Understanding Sonar History

    98x_Manual_531376-1_A.qxd 2/23/2005 11:40 AM UNDERSTANDING SONAR HISTORY It is important to understand the significance of the 900 Series™ 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 32: Understanding Side Imaging

    Side beams look out 240 feet, with a depth limitation of 100 to 150 feet, depending on the contour of the bottom. Please see the Side Imaging Sonar Tutorial at www.humminbird.com for a more detailed explanation. Your Side Imaging transducer also provides traditional sonar imaging at 50/200 kHz.
  • Page 33: What's On The Side Imaging Display

    98x_Manual_531376-1_A.qxd 2/23/2005 11:40 AM WHAT’S ON THE SIDE IMAGING DISPLAY 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.

    98x_Manual_531376-1_A.qxd 2/23/2005 11:40 AM SIDE IMAGING TECHNOLOGY: HOW IT WORKS Side Imaging sonar uses two very precise sonar beams that are directed to either side of the boat and “illuminate” the bottom contour, structure, and fish, and display results in a “picture-like” image. •...
