I only just found this out after watching a youtube video and curiosity made me find a magnet and try it, now I know why my cheepy chinese detector was a real money getter while my new more expensive one hasn't produced as much coin from the same sort of areas. I just thought there wasn't any at the location, but in reallity my machine was discraminating the coins because I never realised they are now made with iron in them!

Hmmm when it comes back from garrett I might have to start digging more iron/foil trash to find em smaller coins.

What I think I did wrong was have my iron disc set too high so it was cancelling out those coins because it finds every other older coin just fine.

Find the occasional 10c that comes up at 75-77 so in goldie range.. usually only dig them in bark when the kids are with me and it's a good way to hone the skills.

I think you have hit the nail on the head mate - Let us know if when playing around with your iron disc whether is improves any - something I really didn't (but should have) do when I had my AT Pro
