Thank you for choosing Humminbird®, America's #1 name in fishfinders. Humminbird® has built its reputation by designing and manufacturing top-quality, thoroughly reliable marine equipment. Your Humminbird® is designed for trouble-free use in even the harshest marine environment. In the unlikely event that your Humminbird® does require repairs, we offer an exclusive Service Policy - free of charge during the first year after purchase, and available at a reasonable rate after the one-year period. [. . . ] Highlight Fish ID Sensitivity on the Sonar main menu. Use the LEFT or RIGHT 4-WAY Cursor Control keys to change the Fish ID Sensitivity setting. (Low = 1, High = 10, Default = 5) Bottom View Bottom View selects the method used to represent bottom and structure on the display. Structure ID® represents weak returns in blue and strong returns in red. 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. (See Bottom Presentation for more information. ). To adjust the Bottom View: 1. Highlight Bottom View on the Sonar menu. Use the LEFT or RIGHT 4-Way Cursor Control keys to change the Bottom View setting. (Structure ID, WhiteLine, Default = Structure ID) Zoom Width Zoom Width adjusts the width of the Zoom window on the Sonar Zoom View. Highlight Zoom Width on the Sonar main menu. Use the LEFT or RIGHT 4-WAY Cursor Control keys to change the Zoom Width setting. (Narrow, Medium, Wide, Default = Wide) Real Time Sonar (RTS®) Window RTS® Window sets the RTS® Window to either Wide or Narrow, or turns it off in the Sonar View. The RTS® Window always updates at the fastest rate possible and only displays returns that are within the transducer beam. (See Real Time Sonar (RTS®) Window for additional detail). RTS® Window (Wide) RTS® Window (Narrow) RTS® Window (Off) To change the RTS® Window setting: 1. Highlight RTS Window on the Sonar main menu. Use the LEFT or RIGHT 4-WAY Cursor Control keys to change the RTS® Window setting.

Increasing the 83 kHz Sensitivity will display additional weak returns and decreasing the 83 kHz Sensitivity will display fewer weak returns. The 83 kHz Sensitivity menu choice is only available when User Mode is set to Advanced (see Setup Menu Tab: User Mode). NOTE: 83 kHz Sensitivity is particularly useful for adjusting the sensitivity of the 83 kHz sonar returns in the 200/83kHz Split Sonar View. The 83kHz sensitivity can be adjusted without affecting the sensitivity of the 200 kHz returns shown in the 200 kHz sonar window. 455 kHz Balance adjusts the sensitivity of the 455 kHz beam. Increasing the sensitivity will display additional weak returns and decreasing the sensitivity will display fewer weak returns. A QuadraBeamTM transducer must be attached to the 700 SeriesTM Fishing System. [. . . ] 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. 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. [. . . ]
