Battery Replacement Interval  

The manual recommends Replacement due 6 years from date of manufacture or 5 years after beacon is placed into service, whichever is first, or after emergency use, The battery should be replaced if the beacon has been activated for any use other than the Self-test

Our customers are finding that after doing a self test they get around 8 years battery life 

We recommend performing the Self-Test at least two weeks prior to a trip allowing enough time for service should your beacon require it.


Rescue response time 

Every rescue is different depending on the location and weather, please read our survivor stories 

if your beacon is not NZ codded the response time will be longer  


Register your Beacon

Registration of 406 MHz distress beacons is a legal requirement in New Zealand. 

Registration is free and can result in a more efficient search and rescue effort.  Digital 406 MHz distress beacons transmit a unique code that identifies a particular beacon when it is activated.

A registered 406 MHz distress beacon will allow the Rescue Coordination Centre New Zealand to access the registration database and find contact details for the owner of the beacon in the event the beacon is activated.


Dispose of your emergency beacons correctly. Lives depend on it.
all beacon activations require an emergency response, even if the distress signal is coming from a tip, It’s  very frustrating for our rescue crews and also time wasting to search, locate and destroy an old beacon giving off a false distress signal, Time would be better spent saving lives don’t you think? 
Only 406MHz distress beacons are monitored by satellite. The 121.5MHz and 243MHz frequencies are no longer monitored and should be disposed of properly .
It is the beacon owner's responsibility to ensure that the beacon is disposed of in a correct manner.
Old or obsolete beacons need to be disposed of carefully, to ensure they are not set off by accident.  Do not just throw them away, as a lot of time and money has been spent on search operations to dig beacons out of rubbish tips. The battery needs to be disconnected and the beacon disposed of according to local regulations, as many beacons contain hazardous materials. Contact your local beacon retailer, or police station, to arrange appropriate disposal of old, unwanted distress beacons.
If you sell or dispose of a registered 406 MHz distress beacon, please let RCCNZ know by phoning 0800 406 111.
For more information about disposing of your unwanted distress beacon, please Contact the Rescue Coordination Centre RCCNZ .
