Well not quite a needle in a haystack but close. I was unloading a load of hay today and noticed that the tray on the elevator that the bales slide down was leaning to one side. There is a pivot on each side of the tray and it was broke on one side, I took everything apart so I cold weld it. There is alot of chaff and loose hay in the area where I was working and I couldn't find one of the pieces that I needed to put it back together, I dug around with my hands and couldn't find it, I said to myself ah ha go grab the Eurotek Pro and set the volume to 11 so Iit would sound off on iron. After about 3 quick swings I got a strong iron signal one of the swings I got a overload signal and sure enough there was the piece I was looking for. Chalk one up for the ETPro and for the iron feature
