What's the oddest thing you've found diving?

[DetectorGuy]

I was trying out the metal detector last fall at Fish Lake near Harris, MN under the floating dock at the public beach and I found a matching pair of earrings. They were big hoop style and probably not expensive but they were matching. They probably were set on the edge of the floating dock and slid into the water is my guess. This is where the plot thickens... I heard about a horse drawn bob-sled that went through the ice on this "Fish Lake" way back in the day. I spoke to a few divers that tried looking for the metal runners and harness parts that would be on the bottom if the story was true. They all looked but no one found anything... Well that day when I was looking for loot under the dock area I found a lot of things and I started to expand my search for loot out in a little deeper water... Mind you that this was only in 7'. The metal detector went off again and I reached into the muck expecting to find another beer can or maybe a pair of sunglasses, but I grabbed on to a large rectangular steel frame about 4'-5' wide and 8' long. This was heavy and suctioned about 18" into the silt. I tried to pull it up but it was not coming up easily. I was just about out of air after about 90 minutes in the water so I left it there. It very well could have been the elusive bob sled, right there at the public beach just a few feet under where all those teens used to hang out for all those years...
