Ocean Signal

<h3>Ocean Signal: Engineered for When It Matters Most</h3><p>When an emergency strikes at sea, the equipment on board can mean the difference between life and death. <strong>Ocean Signal</strong> is a globally recognized manufacturer of electronic marine safety devices, specializing in the technology that connects distressed mariners to search and rescue services anywhere on the planet. Founded in 2008 and headquartered in Margate, England, the brand has built its reputation on a single, unwavering principle: reliable, accurate distress signaling when it counts most.</p><p>Ocean Signal's core expertise lies in <a href="/11545-ocean-signal-epirbslocating-beacons-201934">EPIRBs and locating beacons</a> — devices that transmit emergency distress signals via the international Cospas-Sarsat satellite network to rescue coordination centers around the world. Their flagship rescueME product line spans Emergency Position Indicating Radio Beacons (EPIRBs), Personal Locator Beacons (PLBs), Man Overboard (MOB) beacons, AIS (Automatic Identification System) devices, and Search and Rescue Transponders (SARTs). Whether you are an offshore racing sailor, a commercial fisherman, or a weekend cruiser, Ocean Signal offers a safety solution scaled to your needs.</p><p>What sets Ocean Signal apart in the crowded marine safety market is its commitment to integrating cutting-edge technology in compact, user-friendly form factors. Their next-generation EPIRB3, for example, combines Cospas-Sarsat 406 MHz satellite connectivity with integrated AIS and Return Link Service (RLS) — providing both global distress alerting and real-time confirmation that a signal has been received, all in one unit. The rescueME PLB line is among the most compact on the market while still delivering full GPS-enabled positioning and 24+ hours of transmission time.</p><p>In 2015, Ocean Signal was acquired by ACR Electronics, a Florida-based industry leader in survival technology. This union brought together two elite engineering teams and further strengthened Ocean Signal's capacity for product innovation — while maintaining the brand's distinctly British engineering identity. Today, Ocean Signal devices are internationally approved, IMO/SOLAS compliant where applicable, and trusted by professional mariners, lifeboat crews, and adventurers worldwide.</p><p>Explore Ocean Signal's range of <a href="/11545-ocean-signal-epirbslocating-beacons-200377">emergency locating beacons</a> and find the right device for your vessel and voyage.

Product Details

The Ocean Signal RescueME MOB1 is a dual-technology personal locator beacon that combines AIS transmission and DSC (Digital Selective Calling) communication to dramatically improve your chances of rescue in a man overboard situation. 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.

Dual Alert System:

  • AIS Position Alerts: Transmits your precise GPS location eight times per minute to all AIS-enabled vessels within approximately five nautical miles, with Message 1 (position) and Message 14 (MOB status) broadcasts
  • 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

Technical Specifications:

  • Transmit Power: 1W AIS, 0.5W DSC
  • Frequencies: AIS 161.975/162.025MHz, DSC 156.525MHz
  • Range: Up to five nautical miles depending on conditions
  • Antenna: Sprung whip design
  • Battery: Lithium-ion with seven-year storage life and 24+ hours continuous operation
  • Activation: Automatic on life jacket inflation (first alert within 15 seconds) or manual
  • 30% smaller than competitive MOB beacons

What's Included: MOB1 beacon with integrated battery, mounting hardware for life jacket installation

Compatibility: Works with most modern AIS plotters and DSC-equipped VHF radios that comply with MOB transmission standards. Verify compatibility with older equipment manufacturers.

Warranty: Five years for recreational use, two years for commercial applications
