I was hunting Sunday afternoon in one of my old school yards where in years past they dumped the coal waste from the furnaces. This material attracts to a magnet and can cause weird audio and VDI anomalies in a metal detector especially after a soaking rain. Well anyway I was hunting the area with my Fisher F75 in 4F tones with discrimination of 5 and a sensitivity setting of 60 in BP mode. The machine was very noisy with ticks and clicks and sporadic high tones. After a while I decided to switch to monotone and started digging anything that even started to repeat. I came across a very loud signal and new it was close to the surface, but the VDI numbers were everywhere but mostly in the iron range. Switching over to 4F tone and the audio sounded like pure trash (all 4 tones mixed together in one small location) and I can say for sure I would not have dug this target in any setting other than monotone (actually reminds me of the Tesoro Tejon one tone detector) I also know from experience how some ground conditions and co-located iron objects can cause the VDI to be very bouncy. So I decided to recover this target and at 1

Well...since you asked...yes...I hunt this one really active park..right in the center of town....big concerts, lots of people all summer long, beer tents, carnivals, every weekend some sort of event..etc...anyway, its built with dredging spoils and topped with Foundry waste, all sorts of coal clinkers and foundry sand mixed in with clay...nearly impossible to hunt, like hunting inside of a dumpster..overload city..
..as if the dirt strata wasnt hard enough, theres bottle caps, pulltabs, underground electrical/plumbing lines, foil waste everywhere!
So I drop sens, and high fly the coil..DP tones and go by sound alone...amazing what comes out of there, no gold yet, a couple nice silver rings though, and a lot of clad..i am getting nickels, so its a matter of time for the gold to show up...with that many people, there has to be a chain, I'm thinking, and that signal will be a high iron/foil disasterously soft mess in here. Gotta be at least one gold ring in here too...probably more, so I keep going back and the more I go, the better of a read I get on the place for how to work it. This place has taught me a lot, its hard to hunt on account of it takes focused concentration due to all the signals on every sweep, and flat wears a guys ears out in a few hours.
