Long-forgotten cannonballs resurface
For many years I have been looking for old metal objects with a metal detector. The dream of every collector is finding an old cannonball, which is not easy to do. I knew: There are probably countless of those treasures still in the water. But how could I find them? I almost gave up hope - until I ordered a huge ring magnet .
I used a M16 bolt (middle), a M8 ring bolt with stop nut (right), a M6 bolt with chrome steel flat head (all the way to the left) and a M8 ring (left) to increase the bearing surface of the bolt head. I used a shrinking hose (top) to fasten the nylon rope.
The composition of these parts can be seen on the pictures.
Unbelievable how strong this magnet is! The largest cannonball that I dragged out of the water one night had a diameter of almost 11 cm and was pretty heavy. Meanwhile I fished some smaller ones out of the water. I always have various spectators when I do my "fishing". They are amazed by the huge things I can fish out of the water with this magnet!
