The Mutant Detection Device was one of Bolivar Trask's first major inventions.


The device identifies cerebral output waves along certain genetically common frequencies in order to identify the presence of humans with X-Gene mutations. This technology came standard in every Sentinel manufactured by Trask Industries.


While attempting to sell his Sentinels to various Communist nations during the Paris Peace Accords, Bolivar Trask used the Mutant Detection Device to demonstrate the Sentinels' capability to easily identify any mutant, inadvertently revealing a disguised Mystique in the process.
