I am new to this Hummingbird game. I have a 999 SI KVD on console and a 859DI on the bow. I have watched youtube videos, read articles, etc. But still having trouble setting up everything or knowing what it should look like or what setting to have it on. really all I have been using it for right now is the contour map. I have used the SI and DI a little and have marked a few things, but it just doesn't seem as clear as the videos and articles are or talk about.

Is there a class or a Hummingbird guru that I can hire to gout on the water with me to show me what I need to do?
