By all means if there is anything metal in the cache a metal detector could help find it. but you still would have to swing the coil over the cache. It would help in Ivy and other ground cover.

I signed up today. Then went out and found 2 caches in my area. How do I let people know I found them and that I replaced them with new items in them?
