Integrating sophisticated web-based software and an innovative online platform, the SuccorfishM2m SC4 provides two way, real time communication between an organisation and personnel operating in the field. No other product offers a single, ‘all in one’ safety, communication and rescue solution for lone workers or staff working in dangerous or critical situations.


Valuable data including live operational position of personnel, secure text/email communication, SOS alert, casualty movement and rescue status is streamed back live to any PC, desktop or mobile device via a secure, tiered password protected, graphical user interface (GUI).

Users can allocate administrative permissions and pre-set specific data requirements including personal contact alerts for man overboard (MOB) emergencies. In addition to international AIS-SART and COSPAS-SARSAT assistance, this allows organisations to move fast and deploy proactive and life saving rescue strategies within seconds.
