The SEAYOS Monitor extends the concept of data transfer and communication between diver and observer on the surface to several divers.
This means you can centralise positioning data from several divers and communicate with them. 
It comprises a transceiver unit (typically installed on the boat) communicating with the divers' SEAYOS Pro
and with a tablet (or a computer) enabling the surface observer to have an enhanced interactive display and an exchange of individualised messages.
It also gives divers up-to-date information on the boat's position (particularly useful for drift dives).
The enhanced interactive display is carried out via the SEAYOS Monitor interface (identical to that supplied with the SEAYOS Pro-M, but which in this case enables data management from several SEAYOS PROs), which also offers other functionnalities such as direct data transfer during a dive to GoogleEarth, accessing the exchanged messages log, recording the current session, importing sessions already carried out, etc. 
Note that the SEAYOS Monitor cannot operate independently of one or more SEAYOS Pro units and a tablet (or a computer).
