EPIRB and PLB Spring Check List

If you read THIS POST last week then you know we are trying to help you check the safety gear on your boat before Spring arrives and lots of boating gets under way. This week will will focus on EPIRBs and PLBs. Both EPIRBs (Emergency Position Indicating Radio Beacon)  (**note that the link is very helpful but a bit dated as the 121.5 MHz signal is no longer monitored as an emergency response signal and is now used as a fly over homing signal only**)and PLBs (Personal Locator Beacon) operate in the same way. There are differences including a longer battery life, floatation and deployment options, but they all have a battery life and expiration date! 

EPIRBs and PLBs operate on the 406 MHz frequency, if you still have 121.5 EPIRB you will need to replace it.
Starting on 1 February 2009, the Cospas-Sarsat System stopped processing signals from the deprecated 121.5 MHz and 243 MHz beacons; now only signals from 406 MHz beacons are processed. The switch to 406 MHz is expected to result in a substantial reduction in wasted use of SAR resources on false alerts while simultaneously increasing the responsiveness of the system for real distress cases.

If you have an EPIRB or PLB locate the battery expiration date and check it.

If you do not have one you should strongly consider purchasing one.

The gentleman in this post was not going to buy one but we encouraged him to purchase at least a PLB and it saved his life.

EPIRBs have to have a minimum battery life of 48 hours, they are designed to float in the water up right and transmit a signal, they also have a tether line to tied them to you or your life raft. EPIRBs come in Manual Deployment Versions and Automatic Deployment Versions. The Automatic Deployment EPIRBs have a housing and a Hydrostatic release unit that will set the EPIRB off and release it from the housing, allowing it to float to the surface and transmit. EPIRBs are also available with and with out a GPS transmitter built in. The GPS will help narrow down the search area.

PLBs will have a minimum operation time of 24 hours, they all have to be manually deployed and even though some models float they are not designed to float up right and transmit in the water like and EPIRB. PLBs usually have to be held with the antenna facing the sky. This doesn't mean your signal would not transmit if there was not a clear view of the sky, it is simply the best case scenario. Most PLB models have the built in GPS transmitter which will give rescuers a better idea of exactly where the user is.

So the check list is as follows:

Be sure the EPIRB is a 406 MHz and not a 121.5 MHz operating unit. It is OK to have both.

Be sure the battery is not expired

If the battery is expired find a factory authorized replacement center in your area.

Preform the manufactures self test

If it is an Automatic Deployment Unit check the date on the Hydrostatic Release

(good for 2 years)

Make sure the Housing is in working condition

For PLBs

Check the battery and perform the self test.

Safe boating is the best boating. Come back later in the week as we highlight some rescue stories and introduce you to AMVER (Automated Mutual-Assistance Vessel Rescue System , there are some rescue stories like these that resulted because of AMVER.
