Hello guys. I need a little help trying to figure out my Christmas present. I have a Lowrance x-125 and I've read to get away from the automatic settings. Could someone that has one of these depth finders help me to understand what to change and what to look for on the screen once I make the change.

Or if there is anywhere to read about what to do I'm more than happy to do that. Thanks so much for your time in advance.
