Ocean Signal 740S-01551 RescueME MOB1 AIS/DSC Personal Locator Beacon

Designed to attach to the oral inflation tube of your inflatable life jacket, this compact device automatically activates when your jacket inflates and can also be manually triggered.

• DSC Radio Alerts: Activates the DSC alarm on your vessel's VHF radio, with closed loop calls to a single MMSI number every five minutes and one programmed group call at 30 minutes (where allowed by regional regulations)
• Visual Identification: High-intensity white LED strobe light ensures visibility in low light and rough sea conditions
