Although I've done very well with silver since I bought my etrac, I hadn't really seen real proof that it was as good as everyone claims at getting finds in hunted out parks or from amongst trash. Most of my finds were detected on sites where soil had been moved or removed, and the coins displaced or brought closer to the surface. Yesterday, however, I had my eyes opened. I recently purchased a 12x15 sef coil to go with my etrac, in the hopes of getting some deep finds and covering more area faster. I took it to the park/pool demolishion site where I've been hunting the past few months and after swinging it for a couple of hours in the HOT sun (hittin close to 100 the past few days with extreme humidity to boot), I had nothing to show for it except some frustration. SO...I looked longingly at a big old oak tree and its shade down farther in the park, next to where the old fairgrounds grandstand area was supposed to have been. Everyone and their brother who has a detector in town has had to have swung over that area repeatedly, and this park has been known to have been hunted out long ago by other minelab owners, so I never really figured I'd find anything there but I switched back to my much lighter pro-coil and started towards that big old shade tree. I also made some changes in my settings after reading some posts about discrimination settings and mult-tone conductive responses. So I switched from my usual Two Tone Ferrous settings with a wide open screen to a coin program with multi tone conductive selected, amped up the sensitivity all the way and tried to "listen through" the chatter. About 15 feet from the oak tree I got what I knew was either a silver response or a quarter close to the surface, but the numbers were bouncing all over the place so I wasn't sure...seldom even settling into the silver/quarter area. The sound was clear and warbling like silver though so I started digging......in some of the hardest soil I've ever tried to recover a target in! I could have used a chisel, I dont' mind telling you. Anyways, after checking the hole with my pinpointer, chipping away more dirt and repeating that procedure for at least 5 minutes, I finally got down to about 6 or 7 inches and out of one bottom side tumbled a 1923 Merc.! I was amazed really, I thought for sure the best I would be able to do in that area was to possibly recover some clad change or maybe some jewelry. So I slipped it into my pouch, filled in my hole and started swinging again towards the big oak. I got all the way up to the trunk and started my way around it and got that warble again, right up against the tree and this time about 4 inches deep. No coin this time though, I recovered what I thought at the time must be a small junk jewelry pin made out of what was probably plated pot metal. Perhaps a military pin or something, who knows. But it was time for me to go so I dropped it in my pouch and headed back to the parking lot. When I got the pin cleaned up later I saw the word STERLING on the back and was again amazed. How on earth did that miss detection before?! It's a pretty heavy pin, at least the weight of a quarter or more. I'll have to polish the front a bit but it made my day. So here are some pictures of my "made me a believer" finds, plus a little button that I found earlier. Now of course I went back to the same area this afternoon for about 3 hours and found......notta, one 1965 Washington and a '88 Rosie, and some pull tabs. Definitely going to hit the park again on those days when I don't have better hunting grounds to attend to though!! And that monster 12x15 coil will take some getting used to but I'm betting that I end up finding some goodies with it too before it's over.
