Minelab CTX3030 looking for good targets in iron.

I wanted to give the CTX a try and see if I could see multiple targets on the screen. I tried to look for coins or good targets among the iron. I went to this location because I know it has a lot of iron and a lot of clad coins. I was not looking for signals that sounded good. I did manage to pull a mercury dime but I had stopped filming by that time.
