Dale:
Your right after WWI they did not use them how ever after WWII they
used old surplus mine detectors or detectors based on the type, I
have an old 1950's Mining journal that had as picture of a homemade
device based on the WWII mine detector. I appreciate your response,
if I had 6G's I would not be here asking questions. I will
eventually I will come across some old simple ideas, technology
sometimes can be a blessing & sometimes it's not, because it takes
away the imaginative idea's.
Thanks:

The Proton Mag ForumTerry: I can only give you a few opinions
which is not too important as I am sure you will get better ideas
from others on this forum. Firstly I think your query is OT (Off
Topic) to the best of my limited knowledge on the subject. To my
knowlege Magnetometers were NOT used during or shortly after WWI
because they would have been very expensive AND to my knowledge
they were not very highly developed with the possible exception of
huge units used in submarines, etc. I am certain that MOST (if not
all) of the devices used for finding mines were crude metal
detectors using electromagnetic induction as opposed to the
principals which make a mag go. Therefore in my opinion you will
be better off on a Metal Detector Forum. Based on what you say you
are looking for I would (if it were me) select on of the currently
manufactured "two-box" detectors. There are about five of them.
According to one review that I saw the best for your purpose would
be the Discovery TF-900 which is good down to 20 feet for an
automobile size object. However, remember that if the soil is
heavily mineralized that depth is cut down to maybe half. Second
guess would be the HAYES DS-7 Deep Search SUPER because with their
handle extension they ADVERTISE down to 28 feet. Personally, I do
not like them as well. Shoestring? depends on how big a shoes
string. These units are $400 to $600 new and used about 2/3 that
price if in real nice shape. For what you are looking for I would
not look for anything cheaper. A good commercially produced mag
would cost at leastt $6000 so you are geting a lot of bang for
your buck. I would suggest you find a local detectorist who is
willing to check your site and see how bad mineralized the soil is
as that will have something to do with your selection process.
