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. [. . . ] (See Real Time Sonar (RTS®) Window for additional detail). Transducer Cone and Fish Arches When Fish ID+ is turned off, the Fishing System shows only the raw sonar returns on the display. These returns will often result in "arches" forming on the display, indicating potential targets. Due to the transducer beam angle, the distance to a fish decreases as the fish moves into the beam, and then increases as it moves out again, creating a Fish Arch when this distance change is shown on the display. Boat speed, chart speed, and the position of the fish within the sonar beam greatly affect the shape of the arch. Use the LEFT or RIGHT 4-WAY Cursor Control keys to turn the Fish ID+TM setting On or Off.

Use the LEFT or RIGHT 4-WAY Cursor Control keys to change the Zoom Width setting. (Narrow, Medium, Wide, Default = Wide) Depth Lines (Advanced) Depth Lines divide the display into four equal sections which are separated by three horizontal depth lines. The Depth Lines menu choice is available when User Mode is set to Advanced (see Setup Menu Tab: User Mode). Depth Lines 83 kHz Sensitivity (Advanced) Depth Lines 83 kHz Sensitivity changes the sensitivity of the 83 kHz beam. 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 200/83 kHz Split Sonar View. The 83 kHz sensitivity can be adjusted without affecting the sensitivity of the 200 kHz returns shown in the 200 kHz sonar window. To change the Depth Lines setting: 1. Make sure you are in Advanced User Mode, then highlight Depth Lines on the Sonar main menu. Use the LEFT or RIGHT 4-WAY Cursor Control keys to turn the Depth Lines setting On or Off. Make sure you are in Advanced User Mode, then highlight 83 kHz Sensitivity on the Sonar main menu. Use the LEFT or RIGHT 4-WAY Cursor Control keys to set the 83 kHz Sensitivity.

The Surface Clutter menu choice is available when User Mode is set to Advanced (see Setup Menu Tab: User Mode). Noise Filter adjusts the sonar Noise Filter to limit interference on the display from sources such as your boat engine, turbulence, or other sonar devices. The Noise Filter menu choice is available when User Mode is set to Advanced (see Setup Menu Tab: User Mode). NOTE: The Off setting removes all filtering; Low, Medium and High settings add progressive filtering of the sonar returns. In some deep water situations, the High setting may actually hinder your unit's ability to find the bottom. Surface Clutter To change the Noise Filter setting: 1. [. . . ] 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. [. . . ]
