Sonar Colorline Wide yellow hard sonar return Distinguishes strong sonar echoes from weak sonar echoes. That makes it easier for you to distinguish fish or structure from the bottom. A hard return will be shown as a wide, bright yellow line, whereas a soft return will be a narrow reddish-blue line. Reddish-blue soft sonar returns Range Range set to 60 feet Used to select the section of the water column - from surface to bottom - shown on the display. When there is a portion of the water column you want to focus on, select a range from the Depth Range menu that includes the desired area. The values on the Range menu determine the depth shown on the display. If you selected 20m from the range menu the unit will display 0-20m of the water column, regardless of the water depth. There are 21 depth ranges, including automatic and custom settings. The automatic setting will set the range from the water surface to water depth. Frequency This unit supports three transducer frequencies; two of which are supported by your transducer. 200 kHz has the highest sensitivity and best target discrimination in shallower water; 83 kHz offers a wider cone angle for greater water coverage and 50 kHz provides the best depth penetration. You can view both available frequencies at the same time by setting up a sonar split screen. Split Adjusts the configuration of sonar page display using one of four options: No Split, Zoom, Bottom Lock and Flasher.  28
