The Savox CBU is a modular covert unit that allows the user to customize the covert communication accessory to any covert operation by offering a choice of using a neck-loop or a brooch to transmit incoming communication to the Savox RCR earpiece. While the loop is suitable for most clothing such as t-shirts, the brooch is the perfect solution for female officers as the brooch can be easily hidden under tank tops, shoulder straps, or hand-bag straps. A hard-wired PTT button can be used for half-duplex communication.

The Savox CBU also offers the option of a wireless PTT in form of a key fob with Savox’s unique proprietary and most secured wireless signaling pattern, the SavoxGuard. The key fob offers verbal as well as non-verbal tone communication. Together with the Savox HR6 connector and adaptors it can be connected to a variety of radio models.
