Cody . . . Question . . . iron falsing sounding like deep silver?

[Tony N (Michigan)]

I have a question:

There is this one place where I've been pulling stuff out of the ground at the very limits of my Explorer. In other words, All I hear is a very slight difference in sound from the surrounding sounds but the depth gauge is hitting almost bottom and the cursor jumps from possible good to iron on smart screen.

The question is this:

Aside from taking a lot of time digging down 10 inches or so to locate the "possible" target, sometimes when in pinpoint I move the coil around the area of the "maybe" deepie to see if there is falsing from an iron object nearby. If there is iron within 5" or so I have not been digging. Maybe this is due to my DFX would always hit like silver near an iron object in the ground if the coil got within so many inches of it. Is this the case with the Explorer? Should I dig all signals even if iron falsing could be the culprit? I'd hate to put a million dig holes in this area I'm detecting.

No matter what anyone says, ignorance is not bliss.

You know that the DFX and Explorer has a limitation as do all discriminator no matter if using null or tones and that is there is a maximum depth where a coin is not going to have the ID of a coin. It looks to me like the designers default this last little bet to a low iron tone as a example. So, here are these ultra deep hits that we cannot tell if they are iron or a coin. This is were we end up with a larger coil to bring in that area but then the larger coil has an area it cannot bring in for good identification. This is a problem that I have no answer for other than when I get that ultra deep hit I really watch the digital readings, ICONS, and tune played to say dig or not. Even then I am sure I have passed over good deep targets for the same reason in that how many holes can we dig before we just wear ourselves out? You have hit on the problem that bothers me most with any detector. That was the problem with the first VLF I used, CoinMaster5 I think, in that it had great depth but no way of knowing what the 12" hit was so you had to dig them all. They have the discrimination way down there but we still have the ultra deep hits that are not going to be identified as a good target. I do pretty much the same as you and really work those ultra deep hits to dig or not and when I do and find a good deep coin then feel kind of sick at all the ones I did not dig that may have been a good target. I do fell like the tones, ICONS, digital reading, will give us a fair idea on those hits so if anything peeps through that indicates they may be good then will go for them. I have dug way down there to find a piece of metal, not a coin, that was copper, brass, etc, so have no great answer for this one.
