Congrats on the silver! I have a neat trick for you; On the AT Pro, perform an auto ground balance, and then manually reduce by 5. Switch to pro zero mode, and let the fun begin! You will obviously hear a lot more junk, but silver, especially dimes, will “sing to you.” Mercs and Rosies will ring at 85, I found a Barber dime the other day around 8 inches down that rang off at a steady 82. You might get different results based upon the soil in your area, but my silver finds have gone through the roof since doing this.
