Garmin OnBoard System - Wireless MOB - Tag (Black)

Wireless man overboard detection and engine cutoff marine system

The Garmin OnBoard System provides boaters with a contemporary, wireless solution for man-overboard safety. Rather than relying on traditional kill-switch lanyards, this system utilizes compact wireless MOB tags that can be worn on the wrist, secured with a carabiner, or attached to a floating key ring. Each tag can be designated as either a captain or a passenger within your compatible Garmin chartplotter, enabling the system to respond appropriately if someone falls overboard.

In the event that a tag is lost overboard, the system promptly activates an onboard alarm and marks a man-overboard waypoint on your Garmin display, allowing for a swift return. When the tag is designated as the captain, the Garmin OnBoard system can also disable engine power, assisting in preventing the vessel from drifting further away from the individual in the water. A built-in external beeper on the GOS 10 hub guarantees that the alert is loud and unmistakable, even in noisy operating conditions.

The GOS 10 hub is engineered for the marine environment, housed in a compact 155 × 92 × 60 mm (6 × 3.6 × 2.4 in) casing and weighing only 171 g (6 oz). It features an IPX7 water rating to withstand spray, washdowns, and harsh conditions. The unit operates on 10–35 Vdc and typically consumes around 50 mA at 12 volts. Wireless communication is facilitated through Bluetooth at 2.4 GHz, providing robust and dependable tag coverage throughout the boat.

The Garmin OnBoard System comes with all necessary components for a tidy installation: the GOS 10 hub, a 12-pin fused power and engine-cutoff harness, an external antenna, and a NMEA 2000 tee with a 6-foot drop cable for seamless integration into your existing network (NMEA2000 Network Required, Sold Separately). Additionally, it includes one white wireless MOB tag with a quick-release wristband, along with a carabiner and floating foam keychain. This comprehensive kit is designed to offer boaters freedom of movement while enhancing onboard safety significantly.
