Tag what matters with Garmin OnBoard™ — the wireless MOB detection and engine cutoff system. Built so you can move freely and boat confidently, Garmin OnBoard uses wireless technology instead of the more traditional tethered cords. You can easily designate a captain to allow for emergency engine shutoff should they fall overboard. The Garmin OnBoard system allows for up to 8 MOB tags to be tracked at one time — giving you peace of mind while out on the water. Garmin chartplotter integration allows for automatic MOB waypoint recording at the time of MOB detection. Furthermore, the GOS 10 hub includes a loud external alarm for increased awareness.
- Wireless wearable MOB tags can be worn on a wrist band, carabiner or key ring float
- MOB tags can be designated as either captain or passenger — changing their MOB actions
- Passenger MOB tag detection will trigger MOB on MFDs — plus an audible alarm on MFDs and hub
- Captain MOB tag detection will trigger engine cutoff, MOB on the chartplotter and an audio alarm on MFDs and hub
- Garmin chartplotter integration lets you temporarily disable tags to allow for hassle-free fun on the water
- GOS 10 hub includes a loud external alarm for increased awareness
- MOB tag battery life exceeds a single season of typical operation
- The Garmin OnBoard™ system easily pairs with your compatible Garmin chartplotters
CAPTAIN TAG
Captain MOB detection will trigger engine cutoff, a MOB waypoint on the chartplotter and an audible alarm on the MFDs and hub.

WIRELESS: NO STRINGS ATTACHED
The wearable MOB tags are part of a wireless MOB system — letting you move untethered while still being monitored.

PASSENGER TAG
Passenger MOB detection will trigger a MOB waypoint on MFDs plus an audible alarm on the MFDs and hub.

ENGINE CUTOFF SYSTEM
Should a captain tag trigger an MOB event, the system will cut power to the engines — letting the captain return to the vessel.

CAPTAIN OR PASSENGER TAGS
Through the Garmin chartplotter interface, you can designate each tag as either captain or passenger — changing their MOB action.

WAYPOINTS
When paired to your compatible Garmin chartplotter, a waypoint will be marked at the location where the MOB tag lost connection with the vessel.
