Boaters can ensure their safety in open waters by having a GPS-enabled Emergency Position Indicating Radio Beacon (EPIRB) and Personal Locator Beacons (PLBs) aboard.

These are lightweight, compact, easy to use, and are mandatory to carry on every ship to instantly summons help and provide rescuers with your precise location information.

No one ever wants to be in a situation where an EPIRB/PLB must be activated, but if you find yourself deploying one, the last thing you want to worry about is will the battery hold on until rescue arrives. At LRSE, we provide battery replacement service with state-of-the-art technology signal testing to ensure your beacon is functioning properly.

EPIRBs and PLBs are ideal for voyages where traditional communications are often spotty. Once activated, either manually or automatically by submersion in water, 406 MHz GPS-enabled EPIRBs broadcast a repeating SOS signal with integrated GPS location from virtually any point for 48 continuous hours.

The signal is received by satellites which identify the position on a specified band to locate a lifeboat, life raft, ship or people in distress within a few hundred yards in mere minutes. At LRSE, we’re a fully certified and trained USCG inspection facility and authorized EPIRB and PLB battery replacement center for ACR, McMurdo, and Ocean Signal using only high quality replacement parts and equipment.

Be Serious About Safety as you get ready for your next voyage.

At LRSE we utilize a comprehensive series of tests when servicing your EPIRB.

Before the unit is opened we perform a visual inspection looking at the antenna and its gasket, lanyard and ensure the tamper switch is intact.

The EPIRB is checked to make sure the unit will not activate in its bracket.

We perform a self-test to confirm the unit ID matches the test report, as well as the country and serial number in the report.

After the initial testing phase, we use an anti-static mat to begin the process of replacing the EPIRB battery.

The unit is opened and we look for signs of water intrusion.

The battery is replaced and the unit is reassembled.

The gaskets are greased and installed.

We use a pressure gauge that screws into the EPIRB to assure air retention.

We then repeat the testing phase to guarantee the unit is operating properly.

What can you do to make sure your EPIRB is ready?

Register EPIRB

Perform monthly self-test

Check that battery is in date

Check hydrostatic release

Check for cracks

Check for corrosion

Always remember to register your EPIRB.

The information you provide to NOAA helps to assist in your rescue.
