If it looks like a random "shotgun" pattern, it's iron. A solid target gives a solid point. Also, a target pinpointing to the side of where you detect it is another iron indicator. With time you will learn, you just have put in the hours. Pay close attention to how every target behaves and what it is when dug up.
Thanks Jason I will..
