This portable device is worn on the forearm, and is powered by a standard SEU powerclip. Each use drains one SEU. The device is intended to compare sampled DNA to that worn by the character. Therefore, it can only detect mutated genetic samples of people of the same race as the wearer. On planets where mutation is an issue, Star Law M.E. agents wear one of these wherever they go, and have the right to sample hair or fingernails if necessary.
This method of mutant detection has a 90% effectiveness. If the wearer of the device is also a mutant, it will detect pure-strain characters as mutated as well as all other mutants. No two mutants have the exact same genetic structure, or else they wouldn’t be called mutants; they’d be called a species.
