The Cromwell Echo is a unique helmet system for firefighters with an integral, cordless radio allowing multi-way communications between Controllers, Team Leaders and individual members of firefighting teams. The system can be used in any application, but was primarily designed to overcome the communication problems associated with traditional radio systems when operating in confined spaces or in high ambient noise conditions. The proven system significantly enhances frontline capability by enabling users to transmit and receive information or commands loudly and clearly without distortion, however remote or difficult the location.
