Tocaro Blue’s Master Chief Gateway configures and controls sensor modules throughout your vessel. The Gateway monitors all connected sensors and transmits their data to secure cloud servers over cellular, Satellite or Bluetooth Direct Connect. If cellular is not available due to being offshore or cellular outages, you can always depend on the reliability of the Iridium satellite network. Vessel data is accessible globally when your system is satellite enabled.

In the event of a loss of vessel power, the Gateway has a 7-day battery backup. When offshore, the Gateway stores a record of your voyage to internal memory, and transmits all data to the cloud storage when it reconnects. The Satellite Transceiver ensures vessel location and security data are transmitted without interruption from anywhere in the world.

All Master Chief sensors operate on the high-performance Bluetooth 5 MESH standard. This allows longer range wireless communication that is virtually uninterrupted by boat structural materials. Plug and play Wireless sensors pair to the Gateway for ease of installation and results in minutes.

The Gateway transmits data through sturdy antennas attached by gold, screw-on terminal connectors. Of course, data is fully encrypted when on-air for complete privacy.


Each Tocaro Blue Gateway can be custom configured to fit your unique needs and paired wirelessly with the sensors. It can be tailored to work with any style or size vessel.
