Electronics Help- fish finder

[Big_Bad_Shad]

So I have recently gotten a boat that is better than the tin tub I have been used to. The good news I have put some electronics on it but I know I am not utilizing them up to their potential. Does anyone know any good resources to learn how to better utilize electronics. What setting I should be using ones I should not be using. Right now I am just basically using them for water temp and bottom structure/ depth.. They are both humminbirds. Any suggestions would be helpful.

Right now I feel like I am out of my wheelhouse.

Thanks again
