Thank you BCD you have helped me, What you have to do when your over a target and it reads coins and the bell tone is a nice clear tone, put it in the zero mode, start swing over the target and then start dragging it back to the toe of the coil if it's a bottle cap it WILL go off into the Low tone and coin will stop at a high tone. again a bottle cap will stop in a low tone and the ID will also read Iron.
Some times if the bottle cap is smashed you may have to use the back of the coil and the front of the coil and the ID will also read Iron and low tone.
Now being in the Zero Mode you have to keep in mind you could also be hitting more iron targets in the ground that cause it to go into the iron tone, So this is the reason swing it all the way to the front of the coil and the back of the coil and may be a good thing to turn 90 deg and recheck the target again.
I'm not real good at explaining things some times and hope you understand what I'm saying, If not Please ASK
