I was using the CTX when I got a 09-34 at 7 inches. I dug down but had problems finding it.. it wasn't in the plug but the next shovel I got a chirp with the pinpointer... I located a well worn copper disc.. Thinking really old worn wheat or possibly an IH, I checked it.. Bam first Indian Head in a while! and the date looked small I knew I had gotten lucky.. 1870!! My oldest Indian to date!
