New Garmin OnBoard System redefines boating safety tech
22 October 2025

Wireless Man Overboard detection and engine cutoff system integrates with Garmin chartplotters to give boaters added peace of mind


Garmin, the world’s largest1 and most innovative marine electronics manufacturer, today announced Garmin OnBoard™, a versatile Man Overboard (MOB) and engine cutoff solution for boaters that uses wireless technology instead of traditional tethered cords.

Tags can be worn on a wrist band, carabiner or key ring float, and designated as either captain or passenger. If an MOB is detected, the system will save a waypoint on the chartplotter, and audible alarms will sound. Should the captain fall overboard, the system will also automatically trigger engine cutoff. Captains can also disable the engine via a button-press on the tag if needed. With up to 8 MOB tags, mariners can tag what matters most – adults, children, pets and objects – all at the same time.

Wearing an MOB tag that can activate an engine kill switch on a boat can potentially save lives. As part of our commitment to making boating safer and more enjoyable for everyone, we designed Garmin OnBoard with safety and convenience in mind using wireless, non-intrusive tags that will bring the boat to a stop and alert those on board if an MOB event is detected.

Peace of mind on the water

  • Setup, pair and manage MOB tags from compatible Garmin ECHOMAP™ and GPSMAP® chartplotters.
  • Wireless MOB tags allow users to move freely around the boat without the need for a physical tether.  
  • Chartplotter integration provides automatic MOB waypoint recording at the time of MOB detection, along with audible alarms from the chartplotter.
  • Easily disable tags temporarily to allow for hassle-free swimming and excursions.
  • MOB tag battery life can exceed a single season of typical operation.
  • Garmin OnBoard is compatible with any boat that has an engine cutoff switch and a compatible Garmin chartplotter.
