WARNING!This device should not be used as a navigational aid to prevent collision, grounding, boat damage, or personal injury. [. . . ] This is useful for identifying smaller fish species or baitfish. Selecting a lower setting displays fewer fish from weak sonar returns. This is helpful when seeking larger species of fish. Fish ID Sensitivity is used in conjunction with Fish ID+TM. Fish ID+TM must be On for Fish ID Sensitivity to affect the ability of the Fishfinder to identify sonar returns as fish. To change the Fish ID Sensitivity setting: 1. 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) 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 more information. RTS® Window (Wide) RTS® Window (Narrow) RTS® Window (Off) To change the RTS® Window setting: 1. (Low = 1 to High = 10, Default = 5) 61 Noise Filter (Advanced) 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. To change the Noise Filter setting: 1. Make sure you are in Advanced User Mode, then highlight Noise Filter on the Sonar main menu. Use the LEFT or RIGHT 4-WAY Cursor Control keys to change the Noise Filter setting. (Off, Low, Medium, High1, High2, High3, Default = Low) Max Depth (Advanced) Max Depth adjusts the maximum depth of operation. The performance of your Fishfinder can be tuned to the maximum depth you will be fishing in by setting the Max Depth. When a maximum depth is set, your Fishfinder will not attempt to acquire sonar data below that depth, thus increasing overall performance. When Max Depth is set to Auto, the Fishfinder will acquire bottom readings as needed (within the capacity of the unit). If the bottom is deeper than the Max Depth setting, the digital depth readout will flash, indicating that the Fishfinder cannot locate the bottom. The Max Depth menu choice is available when User Mode is set to Advanced (see Setup Menu Tab: User Mode). [. . . ] Tracks are a useful and quick method to see where you've been, and an easy guide to follow to get you back to the starting point. Generally, all GPS units have a limited number of Track Points that can be saved before the unit runs out of memory and begins erasing the first 113 track points saved. Because of this, the user can adjust the Track Point Interval menu to increase the amount of time between when points are saved, and thus extend the distance covered by a track. Tracks can also be permanently saved to memory, and re-displayed at the user's option. [. . . ]
