The MAR-GE/T Floatable Terminal was designed primarily for Marine equipment monitoring, oil spill tracking, and current/drift studies. This terminal has an integrated GPS data logger, allowing it to report up to 96 accurate positions daily. Little maintenance is required as the device is simple and highly autonomous – it can last up to 250days. The beacon is waterproof and buoyant, allowing it to be spotted easily.

The beacon is simple to install as no special tools are required and can be completed in less than 10 minutes. Operation is also simple as there are only 2 buttons and 1 LED light to indicate the status of the beacon. This terminal can also transmit a “request for assistance message” in addition to the normal positions. When the request is activated, the beacon transmits to the ARGOS system and the GPS position is logged every 15 minutes. Such help requests are directed to nearby fisheries offices to send out a rescue vessel.

Similar to the rest of the products by CLS, there is full global coverage with the ARGOS satellite constellation, the brainchild of various international space agencies. Fredrik Marine recommends using the MAR-GE/T to secure unpowered floating units, which are mainly under the purview of port authorities or to monitor small traditional fishing boats.
