Portable Starfleet devices used to amplify the signal lock of transporter signals in hazardous conditions, such as electrical storms. Enhancers are typically deployed in groups of three, placed in a triangular pattern around the subjects to be transported. Transporter Chief O'Brien used enhancers in 2368 to rescue an away team stranded on a moon of Mab-Bu VI.
