You can talk with the main unit as an intercom. 19.8 ft of extension cable is attached to the unit. Equivalent to JIS grade 7 waterproof construction. Black or white versions available. With the M602 you may plug in up to two COMMANDMICs^®. It's like getting three radio stations and intercom points!
