Multi GNSS
Integrated AIS alert
406mhz & 121.5mhz signals
Introducing the Ocean Signal Plb3 Personal Locator Beacon - 400Bps. The Ocean Signal PLB3 Personal Locator Beacon is an advanced and versatile safety device designed for individuals venturing into remote or challenging environments. It's equipped with a multitude of features that enhance its usability and reliability in emergency situations. The PLB3 operates on multiple GNSS (Global Navigation Satellite Systems) such as GPS and Galileo satellites, ensuring accurate and global positioning capability.
This beacon emits distress signals on 406MHz and 121.5MHz frequencies, providing both Cospas-Sarsat and local homing signals. Additionally, it integrates an AIS (Automatic Identification System) signal, enhancing its ability to transmit your location to nearby vessels and potentially speeding up the rescue process in the event of an emergency.
With its compact and lightweight design, the PLB3 is easy to carry and can be integrated into various life-saving equipment, including life jackets and inflatable personal flotation devices (PFDs). Its robust construction and IPX7-rated water resistance ensure durability even in harsh marine conditions.
The inclusion of an integrated strobe light, visible and infra-red, significantly improves visibility during low light conditions or at night. Moreover, it offers a Return Link Service (RLS) capability, allowing for two-way communication in supported areas.
The beacon boasts an extended battery life of over five years and an operational life of more than 24 hours, providing long-lasting reliability when needed most. Notably, it does not require a subscription, making it a cost-effective and dependable emergency beacon for outdoor enthusiasts, marine adventurers, and professionals working in remote or hazardous environments. The beacon is compliant with various international standards, ensuring its quality, reliability, and legal compliance across multiple regions and countries. The Ocean Signal Beacon mobile app (available for iOS and Android) allows users to access additional functionalities and enhance their beacon's performance.
