Ive yet to put out some photos of the number of things Ive found, and I will shortly. To date Ive found 6 silver dimes, (2 of them barbers), 6 silver quarters, 5 Indian head nickles (one within the first 5 mins of the first time I ever used the Ace). Numerous pennies and many other very intersting things. One day I had a difficult time visually reading my Ace 250. The sensitivity level bars where fading in and out, as where parts of the ID bar, I know it wasnt the batteries. Fortunately it hasnt reocurred. could I have had moisture in there, or would the cold affect it? Any one else experience this? I know on very sunny days , standing to shade it, makes is easier to read, thanks, Osgood.
