I need to know what vid reading you will get on a silver bracelet......I found 2 identical bracelets yesterday minus a clasp on one about 5 ft. apart.....They say 925 Italy....I was getting a bouncey 30 to 35 with sens. at 80 and were probably 3 in. down.....The tone was what made me dig these....Thanks in advance...........Could these be junk
