Two box detector use for prospecting minerals.

Hello
Any one use a two box detector for locating Iron ore / Mineral ore with hopefully gold near by?

Induction and Conductive methods can be used on a Iron vein to help find out how long or the shape of the Iron / Mineral vein is.
Does not matter how small the gold may be as the idea of the two box detector is to look for the Iron / other conductive mineral zone near by.
Also most two box detectors can be used in a "Narrow scan mode" or a separate "Wide scan mode" as two different types of detection scans.

Some people have written that they had success finding  reasonable finds of Silver, Lead, and Copper by using a two box type of detector as well. 
A PI type of detector may work better for Gold itself as some have talked about on the forum in general.

The two box detector  may cover a lot of ground  if the Gold / Silver is in or near the mineral zone that is "Detectable by a two box detector".
There also could be a "Economical amount of minerals / Discovery" in or near this same "Detectable ore or vein" to work at and document as well.

The down side of two box detectors is one could be finding a lot of large scrap iron in the ground as well to sort out.   Any ideas on how to do the sorting out of scrap iron in the ground?

I had a Garrett Blood Hound for a while.  Ran it on a older ADS.  Did what it was suppose to to the most parts but I found it Miss Spent money on my part.  Used it to find Black sands deposits on a few gravel bars but my old BFO could do that.

Thank you for your experience with the Garrett Blood Hound.  The way this one looks at any two box detectors is that the detectors are a iron / crusted mineral / pipe machines only unless one is trying to locate junk in the ground. 
One may be able to use a two box machine on larger rocks only if the rock can be moved. 
Homefire was there any way to move the two boxes back and forth from each other on the Garrett Blood Hound and still use as a metal detector?

Hello
Thanks homefire as this one did not know if there was any way of moving either the Tx coil or the Rx coil or both on the Garrett Blood Hound.  
If the factory set pole distance is say about 50 inches over all one may want to make and experiment with other pole sizes.  The factory pole size is most likely used for locating pipe and larger objects.   A shorter or longer pole should have an effect on the detectors ability of target size response of the "Narrow scan mode".  Anyone experiment with this pole spacing?

Maybe the PI detectors with a large coil have taken over the market say for prospecting?  The PI detectors have some issues as well.  The focus of this topic thread is on old school two box detectors and trying to get the most out of them even if one has to modify the detector or how to use more then one at a time if that helps out.  For example a second person can carry a separate receiver coil say about 20-30 feet away for a "Wide scan" at the same time moving at the same walking speed.  One can also set down the transmitter coil down on or near one end of the target and spiral around with the receiver to help see the size and shape of the target.  This one is wondering if this can be done on any size bolder looking for iron / mineral pockets as well?  One should turn over the bolder to help look over the whole rock and this could be the hard part with the reward  you will likely be the first to do so.

Hello
This one happen to receive a February 1954 Golddak pipe locator guide with the purchase of a older Fisher Explorer detector.  Looks like there should be a lot of people out there who have used a 'Pipe locators' as Goldak Company has been around since 1933. 
This one thinks the two box detectors are a more 'course shot gun method to use first' and then a more 'Pin point method' to use next with any size coil or type of detector one next wants to scan with all the way down to what most call a "Pin-pointer detector" say with just a inch size coil.  A old school Whites Gold detector with a "4 inch probe" away from the ground rock / minerals may also work wonders as well.
 
The idea is to cover some 'New deeper ground' that may have been over looked by the pain and lack of use of "Pipe locators" with a modified use thereof ("No pain no gain"......LOL)  Moving some large rocks can be a real 'Pain'.

Wow thank you for the quick reply there homefire.
The first link has enough English on it to see a over view that they are talking about EM terrain conductivity.  This rings a bell with the 1954 Goldak guide as on page 11 points out “ By switching the set from induction method to direct method the antenna is shorted out and the signal develops in one oscillator coil.  This signal is then directed into the pipe (Pocket, Ore vein) by means of a small copper wire tied directly to the pipe (Pocket, Ore vein).”
“Another method of tracing just one line” (Pipe, Pocket, Ore vein at a time to help with tracing just the one target).

Hello
This one has clicked on the latest link and downloaded and formated into Word to do some homework on.  Hope this one can follow along to understand some or all of the principles there.  Thank you again homefire.

Hello
Reading from the 1954 Goldak "The transmitting unit is quite simple and consists of three basic components; the oscillator or signal generator, the power supply, and the antenna or loop"
So when the antenna is connected to the pipe / iron the signal is strongest on just that target.  Fisher electronics talks about tracing the signal up to 300 feet or more.  Wonder if this can work on iron / mineral ore as well?

By the way the name "Goldak" started in 1933 was manufacturing and selling a kit which consisted of various chemicals and elements for the assaying of gold ore and "it was rightfully named The Gold Assay Kit".
