[. . . ] (Inverse, Gray, Brown, Blue, Green, Default = Blue) Side Imaging X-PressTM Menu 98 Sonar X-PressTM Menu (Sonar Views only) The Sonar X-PressTM Menu provides a shortcut to your most frequently-used settings. Press the MENU key once while in any of the Sonar Views to access the Sonar X-PressTM Menu. NOTE: Menu options can be expanded or simplified by setting the Fishing System User Mode to Advanced or Normal. NOTE: Transducer selection also influences menu options (see Sonar Menu Tab: Transducer Select). NOTE: Quad Layout only appears in Side Beam View with optional-purchase QuadraBeam PLUSTM transducer. Sonar X-PressTM Menu 99 Sonar X-PressTM Menu Sensitivity Sensitivity controls how much detail is shown on the display and will adjust the sensitivity of all sonar frequencies. Increasing the sensitivity shows more sonar returns from small baitfish and suspended debris in the water; however, the display may become too cluttered. When operating in very clear water or greater depths, increased sensitivity shows weaker returns that may be of interest. Decreasing the sensitivity eliminates the clutter from the display that is sometimes present in murky or muddy water. If Sensitivity is adjusted too low, the display may not show many sonar returns that could be fish. NOTE: The Sensitivity setting is a global setting and will adjust the sensitivity of all sonar frequencies, as compared to specific sensitivity adjustments (such as 83 kHz Sensitivity or 455 kHz Sensitivity) which allow you to adjust the level of sensitivity for one specific beam at a time. Sensitivity at Low Sensitivity at Medium Sensitivity at High To adjust the Sensitivity: 1. Press the RIGHT or LEFT Cursor keys to increase or decrease the Sensitivity setting. (Low = 1, High = 20, Default = 10) Sonar X-PressTM Menu 100 Upper Range (Advanced: Sonar, Split Sonar, Big Digits, and Circular Flasher Views only) Upper Range sets the shallowest depth range that will be displayed on the Sonar, Split Sonar, Big Digits, and Circular Flasher Views. The Upper Range menu option is available when User Mode is set to Advanced (see Main Menu: User Mode) and can only be accessed from the Sonar, Split Sonar, Big Digits and Circular Flasher Views. Upper Range is often used with Lower Range. For example, if you are only interested in the area between 20 and 50 feet deep, you should set the Upper Depth Range to 20 and the Lower Depth Range to 50. The Sonar View will then show the 30 foot area between 20 and 50 and will not show the surface or the bottom (assuming the bottom is deeper than 50 feet). Greater detail will be shown for the area between 20 and 50 feet. NOTE: A minimum distance of 10 feet will be maintained between the Upper and Lower Range regardless of the manual settings entered. To adjust the Upper Range: 1. Make sure the User Mode is set to Advanced, then highlight Upper Range on the Sonar X-PressTM Menu. NOTE: See Main Menu: User Mode to change the User Mode to Advanced. 2. Press the RIGHT or LEFT Cursor keys to increase or decrease the Upper Range setting. (0 to 1490 feet or 0 to 497 meters [International Models only], Default = 0) 101 Sonar X-PressTM Menu Lower Range Lower Range sets the deepest depth range that will be displayed by the unit. Auto: The Lower Range will be adjusted by the unit to follow the bottom automatically. Manual: You can adjust the Lower Range to lock the unit on a particular depth. "M" will be displayed in the lower right corner of the screen to indicate the unit is in Manual mode. Adjust the Upper and Lower Range together to view a specific depth range, especially when looking for fish or bottom structure. For example, if you are fishing in 60 feet of water but are only interested in the first 30 feet (surface to a depth of 30 feet), you should set the Lower Depth Range limit to 30. The display will show the 0 to 30 foot range, which allows you to see a more detailed view than you would see if the display went all the way to the bottom. NOTE: A minimum distance of 10 feet will be maintained between the Upper and Lower Range regardless of the manual settings entered. To adjust the Lower Range: 1. [. . . ] 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 track points saved. Because of this, the user can adjust the Track Point Interval 193 Glossary 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. [. . . ]
