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.
