Enhance onboard safety and peace of mind with the Lunasea Lighting Water Activated RF Transmitter & Rechargeable Alarm Receiver. Designed as a man-overboard (MOB) alert system, this compact safety solution instantly notifies the vessel when someone falls into the water—without relying on GPS, cellular service, or satellite coverage.
The water-activated RF transmitter automatically triggers when submerged, sending a wireless signal to the included rechargeable alarm receiver. The receiver responds with a loud audible alarm and visual alert, ensuring immediate awareness so recovery action can begin without delay.
Finished in a highly visible pink housing, this unit is ideal for clipping to life jackets, PFDs, or clothing. The system is reusable, easy to arm, and perfect for recreational boaters, sailors, paddlers, and crewed vessels where rapid response is critical.
Instant Activation: The transmitter sends a signal to the receiver within seconds of water contact, overcoming the "silent" danger of someone falling overboard unnoticed.
Dual-Alert Receiver: The rechargeable base station emits a loud audible siren and a bright flashing light to ensure the crew is alerted even over engine noise or wind.
Multi-Transmitter Monitoring: A single receiver can be paired with multiple transmitters (up to 30), allowing you to monitor everyone on the vessel simultaneously.
High-Visibility Pink: The transmitter housing is finished in a bright pink color, making it easy to locate on a life jacket and providing a distinct visual contrast in marine environments.
Portable & Rechargeable: The receiver is not hard-wired, allowing you to move it from the helm to the galley or cockpit. It charges via a standard USB connection.

User Manual
Test Before Departure: Always perform a "dry test" by bridging the gold sensors with a damp cloth to ensure the receiver triggers correctly before leaving the dock.
Placement: Secure the transmitter to the highest point of a life jacket or the wrist. The goal is for the sensors to hit the water immediately upon immersion.
Range Limitations: While RF signals travel well, heavy carbon fiber or metal bulkheads can reduce range. Place the receiver in a central location with a relatively clear line of sight to the deck.
Maintenance: After exposure to saltwater, rinse the transmitter sensors with fresh water and dry them thoroughly to prevent "false alarms" caused by salt-bridge conductivity.
The Lunasea Water Activated RF Transmitter System is a simple yet powerful safety upgrade, helping ensure fast response and increased survival chances in man-overboard situations.
