Product Features
1.Compact AIS Transmitter with Low Power Consumption
The RSYD-A3 integrates a miniaturized AIS (Automatic Identification System) transmitter that is remarkably lightweight, compact in size, and engineered for ultra-low power consumption—ideal for long-duration emergency use without compromising performance.
2.Dual-Mode GNSS Positioning (BeiDou + GPS)
Equipped with dual-constellation satellite navigation support (BeiDou and GPS), the beacon delivers fast, accurate, and reliable real-time positioning even in challenging maritime environments, ensuring precise location data during critical rescue operations.
3.Dual Activation Modes: Manual & Automatic Water Immersion
The device can be instantly activated by the user via a manual switch in an emergency. Additionally, it features an intelligent water-sensing mechanism that automatically triggers the beacon within seconds of immersion, providing fail-safe protection even if the wearer is unconscious or unable to act.
4.User-Friendly Controls: Manual Test & Manual Deactivation
A dedicated test button allows users to verify full system functionality—including GNSS acquisition, AIS transmission, and LED operation—before deployment. After rescue or testing, the beacon can be manually turned off to conserve battery life.
5.Automatic Distress Alert Upon Water Entry
Once submerged, the RSYD-A3 immediately initiates a distress protocol: it acquires position data, activates the high-visibility LED strobe light, and begins broadcasting standardized AIS Man Overboard (MOB) messages to all nearby vessels and shore-based monitoring stations.
6.Periodic Distress Message Transmission
After activation, the beacon continuously transmits updated AIS distress messages at regular intervals (typically every minute), ensuring rescuers receive the most current location and status information throughout the operation—maximizing visibility and coordination during search and rescue missions.
The life jacket light is equipped with an inverted T-shaped buckle.
1. First insert the inverted T-shaped buckle into the webbing on the chest of the life jacket,
2. And then snap the life jacket light into the inverted T-shaped buckle to fix the life jacket light.
