Im going to a hunt this weekend. I was told the coins are only 2 or 3 inches in the ground. Lots of silver and tokens for other coins and prizes. Hunt is for 45 minutes, so speed is the key, not depth. I dont know if I should use the Explorer, or my daughters new Garrett Ace 250 which is very lite weight. Any suggestions? I have a large cent buried in my yard at 12 inches and guess what? The Ace 250 picks it up great, loud solid signal, a good backup machine for my Explorer. I will let you know how the hunt goes, also a kids hunt. Hope my daughter has fun in that. She hasnt found any silver coins yet, but it wont take her to long. She loves going with me. She is 9YO
