emerald-marine-logo.jpgAlert2 Man Over-board Transmitter
    by Emerald Marine Products
    Model # AT101

transmitter-pouch-layered720xweb.jpgThe Alert2 Man-Overboard Transmitter™ is water-activated and easily attached in the nylon safety pouch provided to a Personal Flotation Device (PFD) or outerwear near the shoulder. Simply arm the Alert2 Transmitter and its long-lasting lithium batteries will power the unit for years; a safety device that lets you set and forget. If the unthinkable happens, and you fall in the water, the ALERT2 Transmitter begins to transmit upon hitting the water. As you come up for your first breath of fresh air, the ALERT2 Transmitter is already alerting the crew on-board that you are overboard.

The Alert2 Man-Overboard Alarm System is the right choice for recreational, commercial fishing, workboat, and commercial shipping, when time is of the essence. The ALERT2 Man-Overboard transmitter is water-activated and is designed to alert the vessel that someone just fallen overboard. As the transmission is on the proprietary 418MHz frequency between transmitter and receiver, the transmission of the alarm begins automatically as soon as the device is triggered. There is no wait for manual activation or GPS coordinates. The most successful chance of rescue will occur while time is of the essence, from the boat off of which the individual just fell. The Alert2 Man-Overboard Receiver will respond when activated with an audible alarm and can be interfaced with the GPS / chart plotter and also to an engine-kill switch. If a visual fix on the individual can not be made, the ALERT2 Portable Direction Finder™ can be used to home in on the ALERT2 Transmitter’s transmission.


  • Automatically Water Activated

  • Can be wired to shut off engine

  • Can be interfaced to GPS / Chart Plotting software

  • A vital addition to any safety plan

Transmitting on the proprietary 418 MHz frequency, the Alert2 Man-Overboard Transmitter must be used with a ALERT2 Man-Overboard Receiver ( sold separately ) to complete the Alert2 Man-Overboard Alarm System.
