Monitoring Application
Get updates on your boat’s battery status, bilge activity, shore power, temperature changes and more. Set up alarm notifications in the ActiveCaptain® app.
Control Application
Get out on the water faster when you turn on up to 5 selected systems, including battery chargers, ice makers and more, from afar via relay switches.
Data Storage
Securely collect vessel data with the GTB 10 OnDeck Hub and store it in the cloud for up to 30 days.
Always-On Connection
The GTB 10 hub uses global 3G/4G coverage.
Backup Battery
A 48-hour internal backup battery allows access to OnDeck after the boat battery is depleted or the power is disconnected.
Full Integration – Compatibility
The OnDeck system is a seamless addition to your current marine electronics (MFD via Garmin Marine Network, engines, NMEA 2000® sensors).
