Oregon prospectors of Minerals and Metals?

Hello
Silly question here has anyone tried using two Falcon metal detectors at one time on the same mineral zone?

To further explain place one Falcon detector directly on the mineral zone of rock then take the other Falcon and scan along the same zone as turning the rock sample.
Will this put the high frequency signal into the mineral zone only or can the signal be 'Amped - up' in native metal as well or maybe both?

Hello
Silly question expanded:
Has anyone tried using say older two Whites Goldmaster probes at the same on a mineral zone rock and turning the rock while 'Scanning' with the second coil?   Sounds like over load to me at close range between the two coils?

Hello
Is there any advantage for using two metal detectors on say a mineralize zone in a rock sample at the same time or is this just asking for a overload signal on the mineralized zone with both detectors being used at the same time?
If a "Two box detector benefits from inducing a base signal into a iron pipe is there the same effect to some extent by using two metal detectors on the same along the target zone?
'Scrub' one detector coil on the mineral zone while scanning with the other metal detector coil down along the same mineralized zone looking for any positive signal is the general idea here.

This of course is asking for trouble however has anyone tried this?
Thank you for at least replying Homefire.

Hello
Two box detectors can use a thin wire as a target to carry a signal if the transmitting coil is 'Direct connected' and non mineralized back ground or soil is the case.  The detecting range may not be very deep however.
 
 One can also take a number of 1/4 inch steel pipes that cross each other under ground and  'Direct connect' the TX coil to just one of the pipes and trace just only that one pipe alone.  This is not limited to the size or length of that one pipe target.  Again the detecting range may not be very deep however depending on the ground conditions as I think water will conduct or weaken the base TX signal?
One maybe able to trace these targets hundreds of feet under good conditions.

Hello
This one forgot that the intent here is to see if any type of metal detector could benefit in a inch to maybe a few feet under good conditions as a prospecting tool to find out the size of a given 'Mineralized zone'.  
Can one also "Null out the minerals" and still scan for flakes or nuggets of metal is the other question that comes to mind?

	Signal injection via two box can be effective on ore bodies too but not going to work on this type target.

This one agrees with this especially with a cheep retail grade of "Two box detector" compared to government grade of "Two box detector" that can go down to up to 100 feet with many times the watts of signal power used. Very big cost as well.
This one is just asking if there is any benefit to using two of the same type of metal detectors on just one long  intended target?   One coil is 'Scrubed or touching' one end of the intended target and the other coil is 'Scanned' down the line of the intended target. 
The learning curve could be really long and painful to check this out?

Hello
Has anyone tried two Falcon detector coils on a wood stick say 5 inches apart to probe at twice the speed a large flat plastic pan of pebbles or along the same mineral zone out in the feild?   The noise may get real bad with both detectors singing at the same time?
No 'Pain no Gain'.....LOL

Hello
Has anyone used a panto graph (4 bar point or pivot point type) to hold a sample test rock with one small metal detector coil under and the other metal detector coil above not inline of each other to 'Scan one side of the rock at a time as the panto graph is moved back and forth?
This could be done with a plastic pan of test pebbles and  two Falcon metal detector probe coils not much detecting range of about 5/8 inch range on each of the two coils maybe?   Still this would double the effective detecting depth on the pebbles one at a time.

Hello
Homefire pointed out:

	Anyone who has metal detected in groups knows that two detectors even if there not the same brand / Freq can interfere with each other.   The same would go with the Falcon.  VLF detectors use Phase Relationship between the  Freq of Tx coil  and  phase of Rx coil Freq to detect.   Introducing a second signal source would not work.  The Falcon uses the variance of Inductance caused by the target within the EMF to detect.  Again TWO signal sources would interfere with each other.

Good points there Homefire and this one agrees.  My current question is 6 - 8 inches far enough (side to side of coils) apart to reduce the two like signals from overloading or 'Cross talk of signals'?
A Ha this one is 'Self-talking'    one's self in welding up a near all aluminum  panto graph with one Falcon detector coil below and the other coil above a plastic or wood tray with say 3/8 inch and smaller pebbles on it to be 'Scaned'. 
This one will use this type of set up to quickly test the out put of the jaw crusher to see if the test rock is worth turning into powder mesh that can take hours and money to do. 

On second thought  will try this first with some 4-5 inch coils first on a gold type of detector.
