USB Single-Use Loggers

Although a low cost solution, you have to gather all the loggers each time to read them one by one. Also, manual PDF exporting and limited customization can be a put-off.


Bluetooth Loggers

More costly solution that comes with its own limitations, like the need to be manually switched off during flight and big battery consumption


GPRS Loggers

A solution that comes with more convenient features, like real-time alerts and automatic upload to the cloud. Unfortunately, it requires a bigger investment and is suited for high value shipments.
