Sonar Menu Commands
The Sonar Menu contains commands for the major sonar features and options. Most of them are only described in detail in Sec. 4, but Sensitiv- ity and Auto Sensitivity are important basic functions that are discussed both here and in the Advanced Sonar section. The other Sonar Menu commands include:
•Grayline command: separates fish and structure near the bottom from the actual bottom, and defines bottom composition/hardness.
•Depth Range command: manually sets the depth range shown on the sonar chart.
•Auto Depth Range command: automatically sets the depth range shown on the sonar chart to always keep the bottom in view.
•Stop Chart command: stops the sonar chart from scrolling. Used when you want to "freeze" the image for closer study.
•Chart Speed command: sets the scrolling speed of the sonar chart.
•Depth Cursor command: displays a cursor line on the sonar chart which allows you to accurately measure the depth of a sonar target.
