I used the Explorer ll with the 1050 coil n a new park.I found this park on an old 1950s Michigan Atlas I purchased off of Ebay for a couple of bucks.The park is about 150 plus years old and huge and probably hasn't been hunted much.I found a 1943 silver quarter 1946 and1964 Roosevelt dime and about a couple bucks of clad and a stupid silver ring.I only found two wheat's one was a 1953 and 1909.This 3 hour search was not too bad for my first real hunt of the year.By the way looking forward to this season and working this park.
