COMMUNICATION EQUIPMENT/WALKIE-TALKIES ARE ESSENTIAL ON SET
Walkie-talkies are hand-held, portable, two-way radio transceivers. They typically resemble a slightly larger telephone handset with an antenna sticking out of the top. Where a phone's earpiece is only loud enough to be heard by the user, a walkie-talkie's built-in speaker can be heard by the user and those in the user's immediate vicinity, which is most beneficial when coordinating film or event production. Other communication devices utilized on set are wireless or wired microphone systems, mixers, recorders, lavaliers and headphones.
