Explorers Iron Mask

[Neil]

Is this feature similiar to the one on the Sovereign? In the Sov manual it says the iron mask feature allows the detector to pick up coins next to ferrous objects, and it indeed does that, at least better than with the iron mask turned off.
On the Xterra 70, the iron mask feature is described as an "expanded ferrous discrimination" and in the Explorer II manual iron mask is only explained how to adjust, so for both these detectors its not defined in purpose like the Sovs iron mask is.

Comments?????

Thanks,
Neil

On the Explorer in iron mask mode you have the option to adjust how much iron you want to hear or don't hear. The same can be done in discrimination mode then go to Edit mode and block out what you want..

The Explorer has 2-D discrimination/ID.

1)The first dimension of disc/ID is conductivity. Low conductive targets ID toward the bottom of the screen and higher conductive targets toward the top. You can discriminate any amount of conductivity or any small notch blackening out that part of the screen which also makes it so no tone is heard in that notch or area.

2)The second dimension of disc/ID is ferrous content or you could call it the "probability of being iron" dimension. High iron content or "high probability of being iron" targets ID toward the left side of the screen and low to zero iron content items ID toward the right side of the screen. You use the iron mask feature to discriminate targets that are more probable to be iron. Just a thin line of iron mask discriminates only targets that are most probably iron. The more iron mask you use the more targets you are discriminating that may not be iron.

The idea of two dimensions addresses the fact that all iron is not a high conductive metal. Depending on the size, iron can ID at the top of the conductivity scale or much lower than the top. That's why all the metal detectors with only one dimension of ID(almost all machines) will often give you a "coin" ID or other ID's with a solid iron piece of metal in the ground. The piece of iron can have the exact same conductivity as a coin or even lower but there is no way for a one dimensional detector to tell you it's iron.

On the Explorer if you have a speck of rusty iron or a big nail or a steel spike or any solid iron target the tone may be high or low on the screen but it will definitely be far left on the screen telling you it IS iron.

As far as hearing a coin next to a nail: in all metal mode(no discrimination or iron mask) you can often hear two separate tones if you sweep slowly. One tone for the nail and one tone for the coin. OR if you are using a little iron mask you'll hear the null(silence of the threshold tone) then the coin tone. Again the slower the sweep the better the separation. HOWEVER, it is not the iron mask that makes the Explorer excel in separating targets. It is the double D coil that gives the Explorer the thin line of detecting transmission into the ground enabling one target at a time to be heard even when they are close.

in both modes, the detector would perform the same?

Thanks much,

I have noticed if i have my machine a little HOT that the conductive numbers may hold, but the FERR numbers bounce. How does that affect the tone and reliability if i switched to FERR sounds? I ask that because a lot of people like to hunt in FERR.
