The Communications Unit, consisting of about 20 volunteers, is responsible for search communications. Formed in the early 1960's, they maintain and operate the Sheriff's Communications Vehicle which is often used as a search command post in the field. They communicate with SAR personnel in the field as well as Sheriff's Dispatch and Allied Agencies. They are responsible for all SAR communications equipment including hand-held radios and repeaters. They maintain and operate an extensive system of Amateur Radio and GMRS Repeaters which are used to supplement SAR frequencies and to coordinate search resources en-route to the search area.
