Putter, the best way to answer your questions is to read the Lowrance tutorial on sonars, [url "http://www.lowrance.com"]www.lowrance.com[/url]. It's pretty basic, so it's a good read no matter what brand of sonar you have. You can get detailed answers to your questions on the tutorial, but I'll give you the short answers:
Sensitivity is how much information is displayed on your screen. You want to turn it all the way up, then back it down to the point where the clutter disappears but you can still see the important details.
Grayline is a feature that helps you distinguish between a hard and soft bottom; ie rock vs mud. Mud returns a narrow gray line, rock returns a wide gray line. Set this to 33%, as per Keith Kavajecz.
Chart cursor must be mfg specific. Download the manual from [url "http://www.eaglesonar.com"]www.eaglesonar.com[/url] and read about it.
Surface clarity, is a feature that clears up surface clutter. Surface clutter is when your sonar returns a bunch of clutter that apears to be on the surface of the water, or at transducer height.
ASP is Lowrance's automatic signal processing, or something like that (I sold my Lowrance 350A long ago). Basically it makes adjustments, whether you're in manual or auto mode to give you the best view of what's below. Turn it on.
The best way to learn your sonar is to put the poles away, bust out the manual, and spend an afternoon putting around the lake and learning all its features.
