    I unfortunately lost my first ResqLink, so this replaced it. I registered it with NOAA and Im all setup again. Great to have when youre out at sea. I kayak a lot and it offers a peace of mind.

    I have the PLB 375 ( old model)

    I cant comment on how it works because to test that feature would cost several thousand dollars after paying rescue teams. However, I have no reason to believe that it wouldnt work. It is obviously very high quality. NOOA registration is a requirement as, once initiated, NOAA handles the actual rescue process. No registration, no rescue. I carry with me on all my hiking trips.

    Actually I hope never to use it, but if the need arose I suspect this unit would be helpful. This replaces a McMurdo Fast Find which Ive had for 8 years and never used. The battery in the Fast Find still shows full charge after all these years, but I thought it best to replace and upgrade. Both are fine units, I just appreciated the longer signal life on the ResQLink. The only downside is the belt clip is close to impossible (dont give up) to attach to the unit and for all the trouble the closure on the belt clip is too wide and doesnt stay on your belt or pack. Also, the antenna can and does deploy when thrown in a bag or pack. Not a big deal, just an inconvenience.

    Primary Drawback.. There are no applicable Rescue Response Insurance Plans. Spot, Garmin, etc all have access to services like GEOS. This does not.

    I can only really give it Zero Stars. A review for something I have not used is no review at all. Its nice looking and small. The Test Button works and the antenna deploys. If I ever use it, I will follow up on this review with my experience.

    Very good experience. Arrived on time great price. Easy to understand how to use it. I go offshore and it adds another level of safety

    My husband purchased this and was very pleased with the ease of setting up and registering. We have had to use it yet, but definitely gives me piece of mind knowing we have it with us.

How An EPIRB or PLB Rescue Works

The Anatomy of a Rescue - Stage 1

When activated, EPIRBs and PLBs send a unique distress signal on the 406 MHz frequency to the Search and Rescue Satellites.

Each beacon is programmed with and sends a unique digital code called a HEX ID or Unique ID. The HEX ID identifies the type of beacon and, Search and Rescue use the HEX ID to identify the beacon registration information provided by the beacon owner.

This information can include: who the beacon owner is, the type of vessel the beacon is associated with (for EPIRBs), emergency points of contact, float plans, trip plans, and much more.

The Anatomy of a Rescue - Stage 2

After the satellite receives a beacon signal, it relays the signal to ground stations referred to as local user terminals (LUTs).

The LUT processes the data, computes the location of the distress beacon, and transmits a decoded alert message to its associated national Mission Control Center (MCC). This happens almost instantaneously after the initial beacon signal is received.

The Anatomy of a Rescue - Stage 3

The Mission Control Center then geographically sorts the data, and transmits a distress message to the closest appropriate SAR authority and another MCC if the beacon is registered to another country.

The RCC (Rescue Coordination Center) investigates the beacon alert and launches rescue assets to find the parties in distress.

Rescue Overview

  • 406 MHz Distress Call Is Activated
  • Search and Rescue (SAR) satellites forward distress signal down to earth Ground Stations
  • Ground stations forward the distress to the Mission Control Centers (MCC)
  • The MCC alerts the closest Rescue Coordination Centers (RCC)
  • The RCC call emergency contacts and dispatch the closest SAR teams
  • SAR teams arrive on scene and rescue survivors
  • Worldwide – Over 48,000+ people rescued since 1982
  • United States – 9,753 people rescued since 1982
