Metal detectors and lost keys

Hi everyone, had one of them days...
It has been wet here but my brother started plowing for me today for the first time this spring. I was at the farm and could hear the tractor working in the field and suddenly the engine starts to stumble and he stops. This goes on for five minutes and then he comes walking back to the farm.
I already know that a corn stalk probably caught the fuel line under the tractor. Easy fix. Grab my keys out of the truck to unlock the fuel pump to fill a jug with fuel also need a screwdriver and a side cutters.
I'm thinking I put those keys in my sweatshirt pocket and they fell out when I fixed that fuel line and now they have been plowed under.
Will a metal detector be able to locate them?
Has anyone else here had luck finding stuff with a metal detector they've plowed down accidentally?
Thanks

yes...not plowed but some buried. Have a White or something like that. A pretty good 30 years ago. They make them much better now.
Also...have large magnet on wheels about 20" wide and have found stuff with it.

Hi... I bought a cheap metal detector from Harbor Freight. Piece of worthless junk (no surprise there). Couldn't find keys in a snow pile with it. That's the only experience I have with a detector and I would never buy a cheap one again.

Yeah, if you have a good one. But it's also going to find every rusty nail and beer tab. If there is much junk around it will drive you nuts. One advantage you should know about where to look.

I just got off the phone with my FIL and he said he would come over tomorrow and search for the keys. I do have a pretty good idea where to look but I've never seen one of these things in action so I'm a little skeptical.

Metal detectors are only as good as the operators, you have to be patient and cover every sq foot. Work in a pattern so you don't miss any areas cause that's where your keys will be. I lost a big bolt out of the front end of my tractor on a Sunday while plowing, 3 hours later and after finding old plow shares and other odds and ends I found the bolt and was back in business, have also used it to find manure spreader links after the chain broke and dropped out in the field.

You should be able to easily locate them if you do it right. Metal Detectors have a discrimination or screening setting. Must be set to accept the keys you are looking for. Might try it on another set of keys to test it. How deep were they plowed under ? Conditions vary and affect depth of detection. It also depends how big that wad of keys is. My key ring could be a boat anchor. Is your FIL knowledgable in detecting ? If he can't find them you would be welll advised to contact a local enthusiast . Some will do it for the thrill of the hunt and a good deed done. Others charge a fee. Findmall.com is one detector website where you could inquire.You may have a club near you. Also Law Enforcement agencies often have a detectorist they call to search crime scenes for shell casings and such. You might ask them. You also could check out White's Website. Contact a dealer near you. They will know someone who could come out and search it for you. Where are you located? I have been a lifelong metal detectorist and have several machines now. One cost me about $1500. It is a very enjoyable hobby. There are not silver coins laying at every search sight though as some people think. Some machines are very advanced with computer technology , multiple modes , etc, Not something one will master in a couple hours . Others are very simple like the wands that they use to screen people at airports. Hope I was some help. Let us know if you find them. Good Luck.
