The GDT-S Prime modem will take care of the transfer of data from the Diver sensor to you, wherever you are, whenever and however you want it. Plus, at any time or place you can perform a remote battery check, run basic diagnostics, receive upgrades, set communication intervals such as measurement and send intervals, and set alarms.

You can receive your data by e-mail or download it via Eijkelkamp DataViewer.

The GDT-S Prime can also be connected to your own web environment by means of API interface, or you can retrieve the data through SFTP.
