I hear talk to a lot of guys and they talk about how the see the fish on there finders and can also see there worm,jig, drop shot on there screen and can even see the fish come up and bite. I have a Lower ancestors Elite 5 HDI combo. I don't understand much about them have used for years but just turn them on and look at depth. Going to start fishing in colder weather and I know I am going to have to start use a depth finder for more than just depth of water and temp. Any suggestions for learning how to use like the other guys do?

To give you a quick reference and idea, go to Cabela's website, look up the Lowrance Elite 7 Chirp and there is a short video clip on there that can give you a quick overview.
