Garmin OnDeck™ Security Sensor

The Garmin OnDeck™ Security Sensor is purpose-built for boat owners and marine professionals who need real-time awareness of unauthorized vessel access or tampering. After years on the water, seasoned anglers and boaters know that unattended vessels face genuine security risks—whether docked at a marina, moored overnight, or stored between seasons. This compact wireless sensor integrates seamlessly with Garmin's OnDeck ecosystem, delivering instant notifications to your smartphone or connected display when motion, vibration, or physical disturbance is detected around your boat.

Engineered to withstand harsh marine environments, the OnDeck™ Security Sensor uses advanced motion-detection technology to distinguish between normal boat movement (wind, wake, dock motion) and intentional intrusion attempts. The sensor weighs just 1 pound, making installation discreet and non-invasive—mount it near fuel access points, cabin doors, engine compartments, or anywhere unauthorized entry poses a concern. Wireless connectivity eliminates the need for hardwired installation, and the ruggedized design resists saltwater corrosion and UV exposure, ensuring reliable performance in open-water and coastal conditions year-round.

This security sensor is ideal for fishing boat owners, recreational cruisers, and commercial operators who spend extended periods away from their vessels. Whether you're a tournament angler leaving your rig docked overnight or a weekend boater securing your investment at a remote anchorage, the OnDeck™ Security Sensor provides peace of mind through proactive threat detection. Compatible with Garmin's OnDeck app and marine chartplotters, the sensor integrates into your existing Garmin ecosystem without additional hardware, delivering actionable security alerts directly to the devices you already rely on.
