Since I've switched to the 6X10 coil I'm having much better luck in iron. Still, I have to pay attention to what Rob said:
To me this means that I must run the recovery delay slow as some of the coins I encounter are very small, though others are as big as Nickels.
Well, First I found a piece of what looked like copper trash, but I pulled out a 2" long piece of iron first. I was pretty shocked that iron that large could be in the vicinity. I was getting lots of false signals on the iron but I know the sound pretty well and can focus on the better sounds. I was running Rx 9, Disc 95, recovery delay 42 and the 5 Band filter. I have to run the delay so slow just in case I come across those small hammered coins that hit around 15 on the VDI. I have the iron tone at 5 and the other tones a shifted to give that flute sound which I've come to enjoy and get lots of info from. No Correlate for me anymore, best data seems to allow the smaller stuff through better. I have my spectragraph set up with Consistency at 8 and the Fade Rate at 3. That really helps to ID small bits of foil (which hit close to some of the smaller coins) as well as clear the smears relatively quickly.
I got a broken signal but it sounded like something was in the iron. I could hit it from just about every direction. Now, I am not digging as much trash with the V3i as I am learning the sounds better and this one sounded ok, not great, due to the iron. The iron was so thick that I had problems finding a place to GB but this area was a little lighter, but you heard iron every swing. I OFTEN can't pinpoint a target as the iron off to the side is stronger than the target! Anyway, around 4" or so down I found this very very small coin. To give you an idea it's about 4/5 the width of a dime, but a dime weighs 2.2 grams and this Silver coin .5 grams! The backside is gone and the front is in ok shape but I have decided not to clean the surface, just in case. I can barely make out the date, but it's there - 1486. That tops my oldest coin by 62 years.
I am not posting this so much as a finds thread, but rather to show you what this machine can do in the iron. The ground mineralization is almost non existent according to the probe and the type of mineralization is iron @ -91 on the probe, so not too bad. But when I lower the coil in pinpoint it usually says 7"-9", so it's a bit of a mixed bag. The iron isn't so much nails as it is decomposing old bits of all different sizes. Some huge and lots small. I look forward to hitting this area with a 4X6 of 5" excelerator in the near future. The guy I went with today showed me this spot and has found 2 bombs from WWII there, so I DON'T dig larger targets!
The picture isn't great but it's the only proof I have. eheh
I hope my settings and story were of some help...
