ALERT2 Man-Overboard Transmitter™


The ALERT2 Man-Overboard Transmitter™ is a lightweight water-activated Transmitter that easily attaches to a Personal Flotation Device. It is automatically activated upon hitting water, instantly alerting the crew of a fall-overboard. Before the Fall Overboard comes up for his or her first breath of air, the ALERT2 Transmitter is already alarming the crew on-board that there is a fall overboard.

The ALERT2 Man-Overboard Transmitter™ is a lightweight water-activated Transmitter that easily attaches to a Personal Flotation Device (PFD). Upon immersion, the Transmitter instantly alerts the crew of a fall-overboard. The proprietary 418Mhz frequency allows it to be automatically activated so it doesn’t have to rely on additional equipment to be triggered.

Easy to Use and Wear
The ALERT2 Transmitter easily attaches to a PFD, offering comfortable MOB protection. It is water activated so the man overboard doesn’t need to do anything to trigger the alarm.

Wired for Engine Kill
For singlehanders and solo fishermen, the ALERT Man-Overboard Alarm System can be wired to shut off the engine in the event of a fall-overboard, enabling the man overboard to get back to the boat.

Plot Overboard Waypoint
The ALERT Man-Overboard Alarm System can easily connect to a compatible plotter to instantly mark the location of the fall overboard. Making it easier to home in the person that fell overboard.

The ALERT2 Transmitter has been saving lives for over 20 years. This proven, reliable, and durable safety device is essential to protect anyone on the water.

ALERT2 Transmitters require an ALERT2 Receiver or ALERT418 Receiver to transmit to.
