Precision target methods and apparatus

A method for determining and retrieving positional information, comprising:

• locating a plurality of first conductive elements on a surface and a plurality of second conductive elements on said surface to form a first grid having a first plurality of intersections, electrically isolating the plurality of first conductive elements from the plurality of second conductive elements;
• coupling a second grid to the surface and electrically isolating the second grid from the plurality of first conductive elements and the plurality of second conductive elements,
• the second grid comprising of a plurality of third conductive elements on a surface and a plurality of fourth conductive elements on said surface to form a second grid having a second plurality of intersections, electrically isolating the plurality of third conductive elements from the plurality of forth conductive elements;
• the second grid comprising a plurality of third conductive elements intersecting each other at a plurality of nodes, the plurality of nodes aligned with the plurality of intersections;
• penetrating the surface with a projectile;
• electronically determining a first location of a first penetration of the surface with the projectile based on a first change in a first electrical measurement of the first conductive element and a second change in a second electrical measurement of the second conducting element;
• performing a plurality of third and fourth electrical measurements on a second plurality of locations of the second grid;
• and electronically determining location of impact.
