Density Probe Wand

A contact wand for checking crate walls, castings, rock faces, and structural panels for voids or inclusions. It gives a quick depth trace rather than a full image, making it fast enough for cargo lines and modest enough for field repairs. Coupling gel must be wiped away between targets. Leave residue behind and the next reading inherits part of the last object's story. Praxis recommends a bench check after hard use; skipped certificates are cheap until an insurer asks for the last valid one. Loan crews sign for Density Probe Wand by serial because its stored surveys can expose claims, routes, and work nobody declared. Returning it clean is maintenance; returning it empty looks like intent.
