A hailer is a fictional item featured in the Defiance multimedia franchise. It is seen in both the video game by Trion Worlds as well as the Syfy Original Series. A Hailer is a piece of communications technology. Hailers can be used to tune to specific frequencies, allow for private chat and can pick up radio signals. Some can also digitally record and scan. Hailers can store names, photos and frequencies of other hailers and their owners for quick communication. The Hailer can also be used as a timer.
