[. . . ] 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. 74 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 indicators: chart depth scale, chart cursor depth and fish symbol depth displayed on the screen. To calibrate the depth indicators, measure the distance from the face of the transducer to the lowest part of the boat. We enter this as a negative 3. 5 feet, which makes the depth indicators perform as if the transducer is lower in the water than it really is. Press so the displayed number shows a minus (­) sign instead of the plus (+) sign. The depth indicators now accurately show the depth of water beneath the keel as -3. 5. NOTE: If knowing the exact depth of water beneath the keel is less important, you can calibrate the depth indicators so they show actual water depth from surface to bottom. To do this, measure the distance from the face of the transducer to the surface (the water line on the boat). This will be entered as a positive 1. 5 feet, which makes the depth indicators perform as if the transducer is higher in the water than it really is. Press so the displayed number shows a plus (+) sign instead of the minus (­) sign. The depth indicators now accurately show the waterline as 1. 5 feet above the transducer. Sonar Color Mode The default color scheme for the sonar chart is grayscale, but we offer other variations to suit your viewing preferences. You can select the chart to be displayed in reverse grayscale, bottom black or FishReveal mode. (For more information on FishReveal, see the entry on that topic elsewhere in this section. ) To change the chart mode color scheme: 1. Press EXIT|EXIT to return to the Sonar Page. Sonar Page & Sonar Chart Display Options The Cuda 250 offers three Sonar chart display options. To choose one, press EXIT to clear any menus, then press PAGES and use the keys to select the desired mode. Full Sonar Chart This is the default mode used when the Sonar is turned on for the first time or when it is reset to the factory defaults. Depth scales on the right side of the screen aid in determining depth of targets. 76 The bottom depth and surface temperature (if the unit is equipped with a temperature sensor or a transducer with a temp sensor built in) show at the top left corner of the screen.
