Nulling over iron targets

Hi everybody,
what happens really when the detector is nulling out the threshold over an iron target? When I adjust it that I don
 
I generally slow down and maybe lower iron mask, the null happens over any target that is disced out not just iron, So its just a matter that since the iron is disced out in iron mask, it nulls.. I do think your right though that straight from a threshold into the null that it takes the explorer a few seconds to adjust to it, so when that happens I sweep over the spot a few times slowly.. as long as iron mask isnt set too high the explorer will still see good targets in the iron null
 
If I am in an area thats a constant iron null, I just back off, cause I just know from experience 26 is too high for these areas..better off running around 20-22 guves the explorer an easier time to recover
 
you talkin about sensitivity? doesn't iron mask run 0 thru -16?
 
yeah sensitivity, if your in iron so bad you cant get a threshold anywhere, then its better to lower the sens as well as your iron mask setting
 
Try using the FAST option. This allows the
Explorer to reset quicker, at the expense of some
target ID and discrimination accuracy. See page 57 of Andy's book.
 
and sensitivity on 26.Did that the other day for kicks on an indian village site thats been farmed forever,,,couldnt go 5 feet without a high conductive iron hit ( even my boot eyelets) this was on fast..buncha bolt heads, brackets, points(cultivator) and quit after 5 or 6,ironmask-6 to -9 for me unless you want everything,,,,boots included,,just my take on it <IMG SRC="/forums/images/csflag.gif" BORDER=0 ALT="::"> cs however no nulls
 
Yesterday I went to an old village site, which was inhabited from about 100 b.C to 1000 a.C..It was full of iron trash, so that the Explorer was nulling nearly constantly. I went slow, Iron mask -9, sensivity down to 22, conductive audio, recovery fast and had many, many false tones (what I thought) like short "blipps" and other non repeatable signals. I was in Audio 3 and in the middle of the iron I had every now and then that "uueee" sound of a good target. And I was lucky. I found one celtic bronze coin about 2000 years old, 3 roman bronze coins (two in bad condition) and a copper coin from 1873. The most important thing, however was, to check the spot where you dig your dirt onto, before you do it! I had several times a good signal, dug it out and then did
 
Herman we dig onto small pieces (2'x 2') or smaller of plastic.If I encounter this problem,I drag the sheeting to move the whole pile.It makes refilling the hole easy..cs
 
Hi Charlie,
this is a good idea. I probably take a small plastic gold pan with me next time to put the dirt in it so I can see if the target is alredy in the pan. Some of our coins are really small, the one roman coin had less than 1/2 inch, so if you dump it on a piece of iron, you probably never see it again.
Thanks.
Hermann
