When I started hunting with my first detector, many years ago, I thought I hit a cache in my back yard. Huge signal turned out to be a big piece of sheet metal, maybe three feet by four feet, buried about a foot down.
A 4X4 ft. Piece of aluminum? At the beach a foot down. Saw a corner of it felt the rest of it. Couldn't dig it up in coming tide. Thought it was a pirates chest! Lol!
I have found a lot of railroad plates and even found a chunk of track less than a foot long. Also found an antique grease gun on my in-laws farm; pieces of roofing from the same old barn too. Weight-wise though probably the piece of railroad track.
I would say the biggest was a 3 by 8 sheet of sheet metal. The heaviest was a piece of cast iron off of a tractor or pump of some kind it weighed probably 40lbs. I found the sheet metal in a yard and the cast iron part while searching a river bed.
Jeff, you win the prize for the coolest hunk of metal. If it has any bullet holes in it then it's even better. Can't get to my shed either due to crazy deep snow.

About 10 years ago I was cleaning all the signals out of my yard, and found a bathtub! The previous owner was a tightwad and didn't want to get a dumpster.
The biggest thing I found is in a farm field, it's probably something left in the ground from oil wells. To dig it I would have to use a backhoe, it's real big.
A long time ago I was detecting around the end of a driveway on the edge of a hill. I had a persistent signal that I knew was something big. Fortunately, the landowner came over and he told me there was the wreck of half of someone's old jalopy buried under there. It had been pushed to the end of the driveway, and eventually became a part of the driveway itself.
I did not keep digging to find out if this was true though... so I cannot verify that it actually was a car.
Water hunting I have found the biggest ring ever, no doubt in my mind. I found a ring eight feet in diameter about 1" thick. It was a large round metal hoop of some sort. This area of the water at one time must have had some industrial buildings there because I found old wrenches and other tools and part. These were about 6" deep in knee deep water at a swimming beach. I rolled the big ring up on the beach and the park employees thanked me and rolled it away.
At another beach I find a manhole cover. The park ranger laughed and said "we have been looking for that". Of course he was just kidding. We pulled it off to the side and he had some of the park employees haul it off.
