ALERT2 Man-Overboard Receiver™


The ALERT2 Man-Overboard Receiver™ immediately alarms the crew and vessel of a fall-overboard situation. Upon hitting the water, the ALERT Transmitter instantly transmits to the ALERT Receiver on the boat, alerting the crew of a man-overboard situation. The ALERT2 Receiver supports an unlimited number of ALERT2 or ALERT418 Transmitters.

  • Water activated to immediately alert the vessel
  • Wired for engine kill
  • Plot overboard waypoint
  • Ability to sound external alarm systems
  • Proven, reliable, and durable

We tested the unit by going the furthest away that we could and getting behind a barge. That test was successful. One of our guys decided to do a real life test this morning, and the Alert2 worked perfectly. Read More

The ALERT2 Man-Overboard Receiver™ immediately alarms the crew and vessel of a man-overboard situation. When the difference between life and death is three minutes, the best chance of a successful rescue is by the crew onboard.

The ALERT2 Receiver is installed aboard the vessel. When the ALERT2 Receiver picks up an ALERT2 or ALERT418 Transmitter signal, an internal siren sounds, and a red “Man-Overboard” light is illuminated. The ALERT2 Receiver also has the ability to be wired so it can shutdown the engine, mark a position on a compatible Chart Plotter, sound external alarm systems, and other options.

Automatically Activated
Upon immersion in water, the ALERT Transmitter sends a radio signal to the onboard ALERT2 Receiver to alarm the crew and vessel of a fall-overboard.

Alerts in Seconds
When every second counts, the ALERT Man-Overboard Alarm System instantaneously alarms the vessel, providing the crew the critical extra seconds needed for a successful man overboard rescue. Unlike AIS, the response of the ALERT2 Receiver is immediate. There is no lag time connecting with satellites.

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 Receiver can be directly wired to the boat’s 12-volt wiring system or connected via an optional 110-volt power supply

An ALERT2 Receiver supports an unlimited number of ALERT2 or ALERT418 Transmitters.
