A question for Eric . I have an early Goldscan but im not sure what model or designation it is . 2 pics attatched of the box .(Would this normally be chest mounted?) The big white stick supports an 11 1/2 inch OD. coil. Some of the components inside the magic box are labelled "checked 1992" . So i presume it is from this period. I'm also desperate for a users handbook . Any help would be very much appreciated. JT.
