Magnetic Camera — 2-D source imaging

A grid of surface sensors reconstructs the field over an area and locates a buried source in x, y, and depth. This is the "turn point sensors into an instrument" thesis, in 2-D.

Move the source under the grid and watch the hot-spot track it; push it deeper and the bloom widens (how depth is recovered). Fewer sensors or more noise lowers confidence. With GPS-time-synced field nodes, this is a walk-the-grid buried-asset imager.
