FE numbers over 12 finding silver and gold

[Bilko]

Hi

Just need to tap your experience.We all know about the 12 axis. What are the highest FE numbers you have seen finding gold and silver, please?

I don't know, I stopped paying attention to the FE number. If it has a good sound, I dig it.

Me too... I often see FE 17's but that's the only number that sticks in my head. Good stuff seems to go higher more often than lower, my guess would be FE 7-18 would be a good range of where good targets fall.

I've seen FE numbers frequently go down as low as 20 on good targets, rarely below this, although some have reported as low as FE24, this mostly happens on the deepies at the edge of detection range, as you remove soil they return to the 12 line. I highly recommend AndyS's coin program as it is open enough to capture this effect but still deals with most iron and iron fulsing. Also, if you have Andy's book, he does cover off on this topic in there somewhere.

In my experience, specific or narrow patterns are good for most of the detection depth, but for the deepies, around the last 2' of dection range, you need to allow for this shift.

I ignore FE numbers when I'm detecting, but you need to be aware of the "FE shift" when choosing your pattern to the type of detecting your doing.

Cheers,
Greg

I been runing mine in quick mask and set at 10 concuctivity and 22 ferrous and notice that the deeper coins will jump a bit more on ferrous numbers and seen coins anywhere from 8-20, but do not lock on and varry 3 or 4 numbers when going over them.

On a target with any depth, 5" or more, the FE seems to be useless. I've dug good targets with a FE all over the scale.

mineralization and nearby iron can really skew the numbers

They can bounce all over.

Try very slow circling of target to get that best signal angle.

Extreme wet soil skews the numbers quite a bit as Bob and I found out this week but the tones remain as sweet as ever on good targets.
