I am looking for a tutorial or resource on properly setting my graph up (hds 7). I've not played with it a ton over the last year but I want to start using its abilities more often. Forgive my ignorance but I feel like I'm missing something. I'd like to be able to decern what I'm seeing... Rock, grass, fish, bait and also structure. Are there settings I should stay away from, lean more heavily on? Sorry if this is too vague but if someone can point me in a direction towards learning to use and operate my graph id really appreciate it. I feel like I could boat more fish and really dissect the water better than just going off maps and known holes

Easiest and fastest is to take a trip with an electronics guide. Otherwise, there are tons of youtube videos to learn from.
