Pulse beacon

Alternate reality

A pulse beacon was a handheld device used by Starfleet in the mid-22nd century.

In 2263 of the alternate reality, Montgomery Scott modified pulse beacons from the USS Franklin to act as pattern enhancers. These devices allowed James T. Kirk and his team to transport into Krall's base, and later for the crew of the USS Enterprise to transport out to the Franklin in groups of twenty. (Star Trek Beyond)
