[. . . ] If this occurs, just decrease the sensitivity to a level that eliminates the clutter. When you turn HyperScroll off, you can return to your original sensitivity level. At left, Sonar Menu with Ping Speed command selected. Ping Speed Control Bar, right, at default setting. To change Ping Speed: 1. (When you reach the maximum or minimum limit, a tone sounds. ) To turn off HyperScroll: 1. When you boost ping speed and switch into HyperScroll, the width of the FasTrack bar graph display doubles in width at the right side of the 78 screen. This allows you to better see the virtually instantaneous sonar returns, just as you would on a flasher sonar unit. For more information on FasTrack, see its entry in this section. Reset Options This command is used to reset all features, options and settings to their original factory defaults. This is useful when you have changed several settings and want to return the unit to basic automatic operation. All the menus are cleared and the unit reverts to the Map Page at the 4000 mile zoom range, just as if you had turned it on for the first time. All options have been returned to the factory settings. At left, System Setup menu with Reset Options command selected. At right, the Reset Options dialog box, with "Yes" selected. NOTE: Reset Options does not erase any waypoints, routes, plot trails, or sonar logs. Reset Water Distance The sonar chart's Digital Data display option includes a box that shows distance traveled, called Water Distance. This information is calculated from an optional water speed sensor, not the GPS. The Water Distance window can be reset to zero using the Reset Water Distance command. Press MENU|MENU| to SONAR SETUP|ENT| to RESET WATER DISThe menus are cleared and the water distance is reset to 0. 00. 79 TANCE|ENT. Set Keel Offset This unit measures water depth from the face of the transducer. Since the transducer is installed below the water surface, the distance displayed by the digital depth, chart depth scale, chart cursor or fish symbols is not the exact water depth. If the transducer is 1 foot below the surface, and the screen shows the water depth as 30 feet, then the actual depth is 31 feet. On sailboats or other large vessels with deep drafts, the distance between the transducer installation and the keel or lower engine unit can be several feet. In those cases, an inexact depth reading could result in grounding or striking underwater structure. The Keel Offset feature eliminates the need for the navigator to mentally calculate how much water is under his keel. Keel Offset lets you calibrate the digital depth, chart depth scale, chart cursor depth and fish symbol depth displayed on the screen. To calibrate the depth indicators, first measure the distance from the face of the transducer to the lowest part of the boat.
