Listen Technologies LK-1 ListenTALK Transceiver

The LK-1 is the individual transceiver that every ListenTALK system is built from: an encrypted, full-duplex two-way unit that lets its wearer talk and listen at the same time on a shared digital channel.

Sold on its own, it is the natural way to add a unit to a system that has already grown past its starter kit, matching the transceivers already in service.
