Got out today for a few hours and finaly found silver I have only had this detector since the middle of April got it from Bart at big boys hobbies great to deal with, anyway I only have time to get out once or twice on weekends so it is taking me a while to get used to the machine but I think I'm starting to get it. Got a high tone 80s 90s at 9inches for the first 2 quarters, then about a foot away got another 80s 90s high tone at about 10 inches and found the other 2 quarters. I was excited to say the least. Ground balance 63, sense 87, disc 0. Thanks for looking Bill
