The McMurdo brand has been synonymous with world leading, cutting edge technology for GPS Location Beacons for decades.
McMurdo is now under the umbrella of Orolia Maritime, the world leader in Assured Positioning, Navigation and Timing (PNT) solutions that improve the reliability, performance and safety of critical, remote or high-risk operations.

Orolia have made tremendous advances in location technology with an even greater degree of positional accuracy and the added benefit of their specially developed Reassurance Signal:  Galileo and ReturnLink Rescue Solutions

Jimmy Green offer you a select range of Orolia Locator Beacons.


Horses for courses is how the old saying goes - an EPIRB (Emergency Position Indicating Radio Beacon) is the main distress location beacon on board, registered to the yacht - a PLB (personal Locator Beacon) is pocket sized for the crew or the Safety Grab Bag



5 essential EPIRB checks before going afloat:

  1. What is the very first thing to do?
    Check that your EPIRB user registration is up to date, if the EPIRB is new to you then make a registration as soon as possible: Register your EPIRB
  2. How is my EPIRB switched on?
    Most EPIRBs can be automatically or manually activated. Automatic versions will have a hydro-static release mechanism (HRU) that will release it from the bracket so it can float to the surface and start transmitting.  Do it now, familiarise yourself with your EPIRBs manual activation ON switch procedure and how to release it from its mounting bracket.
  3. I want to make sure my EPIRB works, can I test it?
    The EPIRB should only be live activated when you are in grave and imminent danger. However the EPIRB has helpful built-in self-test features. Operating the self-test allows the entire unit, including electronics, battery and antenna, to be tested without generating a false alarm. Check the EPIRB user guide for the exact instructions regarding how to start and read back the results of the self-test.
  4. What to look for when checking if the EPIRB is installed correctly?
    An automatic EPIRBs mounting position must have clear access around it to allow the lid to open cleanly and the EPIRB to float free clear of overhangs, vessel rigging, antennas etc. And not be mounted where damage is likely by direct impact from crashing waves or placed where it could be a crew tripping hazard or an unintentional grab handle. An automatic EPIRB has to sink to roughly three meters before it will be released from its bracket, so remember to take this into account when deciding on the mounting position. Avoid the possibility of engine exhaust fumes, powerful heat sources and chemical or oil interference. Easy access in an emergency is of course very important as well.
  5. How can I easily identify any potential defects?
    Careful visual inspection on a regular basis is the key. Metal parts should be bright and free of rust. Plastic parts should have no visible cracking. Over time, plastic and paint finishes may start to show signs of fading but clear plastic parts should remain reasonably transparent. No water droplets should be visible inside when looking into the clear plastic dome. Check that the battery and hydrostatic release expiry dates are valid. Verify that the lanyard cord is securely attached to the EPIRB body and not tied off to the vessel or the mounting bracket.

PLB safety checks before going afloat
  1. Register your PLB
  2. Check how to activate it.
  3. Perform a self test regularly.
  4. Keep it on your person when at sea
