Is there a "BEST" frequency for...iron?

I know...who wants iron???
A meteorite hunter.

Would there be a "best" freq? Or is iron so easy to find that the frequency won't matter? Only the coil size would matter....???(large area or fine detail?)



PS Would there be any way of discriminating out those pesky gold signals?
LOL!!!!!!

After the way I see that I worded that post.....

I AM serious about the iron question.

It seems that on the Xterra the 18.75 KHz hits harder on the Iron as fo the DD coils. Not sure how that relates to other machines.

You could reject all high numbers except 48 . Or what I would do is just set it with two tones and dig every low tone.

If you are hunting out in the middle of nowhere, I would just put it in Prospecting Mode on the 70/705 or run in all metal 2 tone on the rest of the Xterras......MO

Well the low frequency coils work best for high conductors, and the high frequency coils work best for low conductors. Since iron is a low conductor, I would go with the 18.75 khz ten and a half inch DD coil.
