Blue water cruisers, sailors and mega yacht deckhands understand the seriousness of a man-overboard situation. When every second matters, the key to a successful recovery is a quick response by crew. Emerald Marine Products’ ALERT418™ Man-Overboard Alarm System is a water-activated transmitter that instantly sets off a cabin or helm alarm when submerged, without the delay common with systems that rely on satellite signals.
The ALERT418 Transmitter is a small, lightweight device that’s attached to a PFD or harness. It runs on two CR123 lithium batteries and has six flashing LED lights for increased visibility. A red LED flashes when power is low. For wet conditions, a Spray Tight Pouch is available.
When immersed, it sends an instantaneous signal to the ALERT Man-Overboard Receiver that automatically triggers a piercing 95dB alarm and bright red flashing light on the display. It can be wired to set a waypoint on a compatible GPS chart plotter, activate external strobes and speakers, and/or stop engines.
Unlike devices that rely on AIS—either by manual activation or equipment such as an auto-inflating PFD—the ALERT418 Man-Overboard System responds immediately. There is no satellite lag.
System comes with a transmitter, receiver, 15” flexible whip antenna, 25’ of coaxial cable and mounting hardware. www.emeraldmarineproducts.com
