Ground search,Metal detecting
Radar

How deep will a good or very good metal detector go ? I need some thing that will cover a very large area and go as deep as a Army Air Corp Major would dig with a shovel.Any suggestions ?

and is a pain in the * if youre wanting to do a gris search of a large area.
Here are some that will go up to 100ft depth. [:D]

Nothing like it from my experience.
Thats what i need,one i can pull behind a ATV.Anybody know how many 45s were packed in a wood shipping case ?
Well, the cat's head is out of the bag, might as well let the rest of him out, now!
Haven't heard of anything ever being found tho!! Tom
Regardless of depth; a Schonstedt will find them. It will also find trace metal, rebar, steel beer cans, and other detritus if you don't adjust it correctly.
I have recovered monuments set by the Spaniards in the early 1600s that were iron and 15' deep in volcanic soil; try THAT with a coiltoy!
Your best bet would be to map out your search area into a 10'X10' grid, and just walk the lines for a week (if it's only a 2-square-mile area, shouldn't take that long); they've been there for 50 years, and aren't likely to move around a lot. You're seeking a BIG signal.
Let's know if you find anything. If not the 45s maybe something just as interesting.
The Professionals use Schonstedt gear; if it's got a big flat coil it's a TOY!
I was able to buy TWO of those sets for $600 each off the Goodwill website, and BOTH were fully functional! Sold them on eBay; $800 for the 1st, $400 for the 2nd, so I came out even (I always start my auctions at a penny - a TRUE "No Reserve"). Guess the people didn't trust my accounts of testing them out. They should have sold for $1K or more each.
Out there if you're lucky enough to find them!!! But be ready to pay big money. Is the expense worth the reward? Any hints to what you're looking for? Maybe hiring some ground-penetrating radar may be the way to go, IF the reward justifies the cost.
garrett makes a nice deep scan device that looks like something out of a sci fi movie. it will detect cabins and caches. this will be the one used by the nazis to detect your guns in the walls and in the yard.
i use a minelab and can find almost anything within a few feet. past that, you pay some major bucks. even if you get a good one or rent one, you need to train how to use them. the trick is discrimination,.
like the guys have said. depends on the object you are looking for.

If i find them you might see a picture of one now and then on GB auction for unissued 1911A1 just out of cosmoline,but this is going to take awhile to work out the details of the hunt.
Radar,
Okay, calculations aside, let's get serious about figuring this out for you.
What kind of terrain is this (pasture, forrest, desert, etc.)?
Are there any notable old building sites or unique ground features?
Are there any areas that could be eliminated (lakes, etc.)
Being as they didn't have GPS when they were buried, they must have put them somewhere they could find them again.
Have you tried to dig up any maps of what the area looked like around the time they were buried?
They would have been heavy, so they probably wouldn't be far from a trail or road where someone could have gotten to on horseback or by car. They wouldn't have carried them far by hand.
Do you have any notion of how they were packed? If they were just loaded in a crate and buried in moist ground they'd be rusted chunks of metal.
Its mostly farm ground ( row crops )so it would be clear for looking after fall harvest.Some buildings but he would not of buried close to them i dont think he would have put them where they would have been dug up as he was to get rid of them,they were to be buried to get rid of them.I can get new sat.photos of area but so far nothing of WWII vintage.He most likley used a jeep to haul them to where he buried them.They were in their shipping crate packed in cosmoline.I knew this guy pretty well and he would not have made up a story about this if it was not true.
CLUE-farmland is usually dug into once or twice a year and may be subject to erosion, new fences, piles of old fencing metal, etc.; so you have to take into account where the fields were at the time he was caching the items.
www.terraserver-usa.com will give you recent satellite photos if you have coordinates or the name of a town nearby which you can swap to a topo view that gets more detailed as you zoom in. This is useful because the topo maps will be older than the satviews, and might show old jeep trails and such that aren't readily apparent from the photos.
Seek out a local surveyor or aerial photographer to see if they have older photos of the area, and check with your State Highway/Road dept.; they may have aerial photos from past surveys nearby.
If I were there, I could use my software to estimate the best possible places to start looking due to infrared analysis of the photos, but then I'd want HALF!
Did he have an area where he got rid of trash?
You say he 'got rid' of them; are you confident he didn't destroy them...or bury them unprotected where they would destroy themselves? It sounds as though this were intentional. Any idea of his reason (i.e. trying to keep them from someone else, kids, etc.)?
Just trying to eliminate things.
Did he live on the property in question?
Here's where I'm going with this... If he was trying to keep them away from someone in his house then you can rule out anywhere nearby or within sight of the house. If he was trying to keep them away from a neighbor then they will almost certainly be within sight of the house. Lastly, if he was just disposing them because he no longer wanted them, or thought they represented something bad, then they're probably where he disposed of any of the rest of his garbage (which will be an area that is not farmed).
Any idea about the time of year he buried them? If he was in crops then he wouldn't have risked damage to the crops to dispose of them. If it was winter he wouldn't have been able to dig very much.
I'd concentrate on areas that were the most distant from any people, but adjacent to a road or path. Perhaps a low spot (which is bad...condition wise).
If he didn't want anyone to ever find them then chances are he didn't put much thought into their condition decades later. Perhaps go stand on the property where he spent the most time and look around and ask yourself...'if I wanted to bury something where no one would find it, where would I put it?'
He was a Army Major that was to dispose of no longer needed gov. property,the 45s were not disposed of in the same way other things were and since they were in cosmoline they will last a hundred years. Gunnut will infrared show where soil has been dug and maybe a diffrent layer mixed in.I know since the end of WWII the groung has been tilled alot but there might be some diffrence.
You should be able to discern from aerial photos where the ground is/was disturbed; where old trails were, old dwellings, etc., and then match that data to older topographic maps to start your layers of GIS (Geographic Information System) and land use through the years.
I would start with locations of old outhouses. More than yesterday's lunch has been discovered in them.
good luck with it and keep us posted.
