Thanks.
This is a picture of the actual quarters before I picked them up. Some were loose and some were stacked, but the were all very close. I think the TID was jumping around between 30-35, but it was a very solid hit. I was using park mode 2 with the sensitivity on 18.
As far as being able to compare the pre and post firmware updates, Icant, because Ive only used the detector post firmware update.
