I ran some coins across my coil this morning and noticed something odd The Indians and Wheat type coins were not being picked up by the detector. The other coins were. I tried everything but nothing worked. I finnaly changed the DST from On to Off and it started finding the Indians and Wheats again. Just my experience. You might want to check this out on your detector. I did find a indan last month with this detector but none in about a month. Could have been this gitch.
