I have tried looking at several other websites and at the owners manual but am still having a hard time figuring out how to use the structure scan effectively on my hds 7 touch. Everything looks like a tunnel down the middle in light brown and darker on the outside. I know i am not looking at it correctly and using it correctly. I am not sure what i should be looking for on the unit. This is my first gps/ depth and fish finder. I am lost. any help on using the product will be great. thanks
