there is any machine that can locate buried iron from a distance?

xexe!!many machines are:)but you mast know how are working:)

Well,if its inside iron box,maybe you cant detect with any LRL,becouse the iron box is a shield and not aloud the elctromagnetic field from gold to grow,this only happens with ground contact and the coins.Forget any LRL...
So,if you have some MAGNETOMETER used for divig&shipwreck try to use there,can detect the box 100 meters or more,but i dont know if works out of wather...

You can use magnetometer for iron box. Also I experiment for iron, but it demmands a coil with some thousands ohms and need to move the pistol when you're searching. Distance is not much, only few meters. Better here small coil (3,000 ohms or more) winding around ferrite or iron.

But, of course, any iron of the size of a very oxided nail can be detected at 1.5-2 meters of the pistol... problem!

I build a MD with this coil winding around iron and can be detected a "magnetic sand" whe called here, seems is a type o "magnetic depression" in soil caused by iron minerals. I think that can be good for meteorite, but no for much depth. This is a "short range" magnetometer.

Only trough resonance and magnetic waves, provided they are very well tuned.
Not possible to conventional long range field type detection due to the extreme short size of iron emanation. Less than 30 degrees in the vertical axis.
