RELAX — CORTEX IS ON WATCH FULL TIME

The Cortex M1 hub combines advanced collision avoidance technology with proactive alerting plus remote monitoring and control of onboard systems from your compatible smartphone

Features may include:

A high-speed smartAIS transponder transmits your boat’s location and heading and proactively warns of certain collision threats.

In addition to collision alerts, smartAIS will trigger alarms for anchor drag or man overboard (MOB) situations.

This hub comes VHF-ready. Simply add a Cortex handset (sold separately) for full VHF radio capability.

Cortex apps let you monitor boat systems, receive alerts and remotely control devices from your compatible smartphone.

A GPIO port and supplied cable allow you to monitor bilge pumps, security sensors, shore power and more.

The NMEA 2000® network allows you to view Cortex data on your connected MFDs and chartplotters.
