M25 Sentry Kit Includes Sentry Adapter Cable, Float Switch, Magnetic Contacts, Backup Battery, Sensors & Actuator

mazu Sentry is an add-on for the mazu Satellite System. This kit includes all the essential equipment needed to monitor and control a vessel from anywhere in the world.

mazu Sentry uses 100% global, reliable service using the Iridium satellite network. Unlike cellular connections, satellite delivers status updates and provides remote control vessel access in remote ports, during extreme weather, and in other situations where cellular service isn’t available. mazu Sentry saves needless worry and gives the assurance of a safe and relaxing voyage, or peace of mind when not with the vessel, by providing a connection you can trust.

The interface is easy to use and makes monitoring systems and controlling devices a breeze. System allows connection of 4 sensors or actuators. mazu Sentry connectivity is available as an add-on for only $10.00/month for customers on an active mazu connection plan, and $24.95/month for customers on a non-active plan.
