The MetalMapper 2x2 is a specialized instrument used for the characterization and discrimination of UXO (unexploded ordnance). The instrument uses an array of transmitter coils and receiver cubes to measure the EMI (electromagnetic induction) response of buried metal targets in the ground. Using software inversion algorithms, the data is used to discriminate targets of interest (TOI) from scrap metal.

Most metal UXO larger than a 37mm projectile can be discriminated from scrap metal. It can be difficult or impossible to discriminate smaller munitions like 20mm or small arms rounds. The MetalMapper 2×2 cannot be used for anti-tank or anti-personnel landmines, or for other UXO that is non-metallic.

The MetalMapper 2×2 can usually detect all UXO targets of interest to depths of 60cm, and larger TOI to depths of 1m or more.
