Deep nuggets and Big coils

[Anonymous]

Hi all
I am considering the purchase of a large coil for next years gold hunting but there are a few unanswered questions that are bugging me.
According to all reports the big coils are just not getting the results that they should be. There must be some big nuggets at depth that have not been found as yet. According to the list of Victorian nuggets many big nuggets were found at various depths from 1inch (the Welcome Stranger) down to about the twelve foot mark. A considerable number were in fact found at the 12 foot mark but many were at lesser depths also. I consider that the 12 foot deep mark is just too great to be realistic but there should still be some at around the 6 foot or less mark but the current crop of detectors and coils don

Eric Foster (awhile back on the Geotech Forum I believe) that a 2 box PI detector would get the deepest of all configurations for the big nuggets. Now if he could come up with such coils for the Minelab's that would be neat too (or Coiltek or ?).

to me is something that has been done all along, to scrape the ground with a piece of equipment and re -chain the area. It is not only the larger pieces you are after, but the many hundreds of small pieces that Actually pay for an operation, that are now within detection range. Detectors of all types have their limitations and always will have, so an interim method has to also be employed, and if the ground has been a good producer its worth the expense...Geo

Steve interesting results good results with the much maligned 11ins dd I think its still the best all rounder.
What we need for the deeper large nuggets is a twin coil set up like the garrett blood hound unit for the SD`s Coiltek get to work!

All detectors have a limit to their range according to power limitations.
Even with larger coils that range is still
limited.
How far can you detect your car from the
detector using its biggest coil.
Now down size the target and you start getting
the limit of its range to that size target.
Ground conditions will vary the distances but
not to any great magnitudes.
I would'nt expect to find a large nugget as large
as my car much farther than I can detect the car.
For that size I would be using a Fisher two-box
unit that will detect a car almost 20ft in the
ground.
