Man Over Board sMRT V300-PLB

The sMRT V300 is a commercial-grade Maritime Safety Locator Device (MSLD) featuring AIS, VHF DSC, and the 121.5 MHz emergency frequency for improved localised alerting, tracking, and recovery. With both manual and automatic water-activated activation, on immersion for 2 seconds, it enhances the speed and efficiency of MOB recovery.

Specifications

General information

With water-activation technology, audible and visual indicators, and multiple fixing options for life jacket integration, the sMRT V300 significantly enhances the speed and efficiency of MOB recovery. Additionally, its increased signalling range and Class M compliance guarantee accelerated signalling and reliable tracking over extended distances. This advanced technology enhances safety and effectiveness during man overboard incidents.

Features

  • VHF DSC: Nearby vessels are automatically alerted about the man-overboard situation via DSC technology
    • Dual GNSS: Integrated GPS and Galileo receivers ensure rapid, global detection, enhancing accuracy in locating the individual
    121.5 MHz: Features a low power homing signal to assist marine and aviation rescue efforts
  • Strobe Light: Features a high-powered strobe light for enhanced visual identification during night-time, aiding rescue efforts in low-light conditions
  • Arming Door: Includes a swing door mechanism to prevent unintended arming and activations, reducing the risk of false alarms
  • Dual Activation Methods: Can be activated manually or upon water immersion, ensuring functionality even if the user is incapacitated or unable to activate the device
  • Test Functionality: Enables manual testing and app-based compatibility checks for power and functionality status, allowing users to verify device readiness
  • AIS: The live location of the individual overboard is continuously updated and displayed through AIS technology
  • Water Activation: Activates automatically when submerged in water for 2 seconds, ensuring a swift response in emergency situations
  • Coloured LEDs: LEDs change colour based on the beacon's status, providing visual cues for device functionality and alerts
  • Audible Alarm: Features an audible alarm to aid in location and alert users of potential false activations, enhancing user awareness
  • Environmental Consideration: Packed in 100% recyclable materials; batteries replaced only by approved service centres, promoting sustainability and responsible disposal
  • Waterproof Design: Designed to withstand water exposure, ensuring durability and reliable performance in marine environments

    • Class-M Compliance
    • Compliant with European regulation ECC/DEC/(22)02 pertaining to MOB device usage, ensuring adherence to international standards. More information about Class-M can be found here.
