Hit my first gold ring yesterday with the f75, A hefty, 1977 10k high school class ring. I was in tones 3h and received mid and high tones with readings of 53 to 71. I pinpointed the high tone, 70 reading and at 3' recovered a clad dime. Checking the hole again, I got the mid tone and a 53 to 57 reading about 2" out from where the dime was. After pinpointing, it locked on 53 and at 4", out popped the ring. I was hunting beside the sidewalks leading to athletic fields. HH jim tn
