Hunted a park that i've hunted a lot before except for one corner. had the 12x15 SEF coil on. Started running pattern's just inside the fence. Didnt take long for my first target. A tire gauge at 8". Kept working away from the fence and it was a while before i got another hit. Sounded realy good from one angle not to bad from the other. Dug a 6" plug an checked with the probe ...still in the hole. Dug another 3" and had a sweet sound in the plug. broke it open thought i had a standing lib quarter but it was a 1912b 1 fr. coin.Rechecked the hole ...another target just off to the side at the bottom...a 1889 ih. Put the plug back and rescanned the area like i always do,and about 5"over i get a weak nickle signal. At about 7" out pop's this square 5c coin. Hunted a while longer found a 1919s wheatie and printing plate for an add for sealy mattresses. thank's for looking AL
