I started out with an ACE 250 and found many wonderful pieces. Then I got into relics and got a Tesoro Tejon, which I love. But, I still like tones. My current dillema is ......... go with a Tesoro Golden for its tones but seemingly slight weakness in depth ability. Or go with the AT Pro. I have a place in my shriveled little pea of a heart for Tesoro, but the AT has so much to give ! What kind of depth (no BSing please) are you getting for an old silver dime and old small copper cent in moderate soil ? Thank you.
