Ever wonder how we test emergency beacons without triggering a Coast Guard response? 📡
Sean, our Safety Service Department Manager, walks you through our EPIRB testing process—because when your life depends on a signal, "hoping it works" isn't good enough.
Our Testing Protocol:
Step 1: Visual Inspection. Check for cracks, corrosion, and physical damage that could compromise function.
Step 2: Self-Test. Verify the beacon's internal diagnostics are reporting correctly.
Step 3: The Faraday Cage. This is where it gets interesting. We place the beacon inside a specialized cage that blocks the signal from reaching the Coast Guard, while a handheld device inside acts as the satellite receiver.
Step 4: Live Signal Analysis. We activate the beacon and measure:
406 MHz frequency (satellite signal)
121.5 MHz homing signal
Power levels across all frequencies
Signal integrity and transmission quality
Why test BEFORE changing the battery? Because we need to know the beacon actually works. A new battery in a broken beacon doesn't save lives.
Same rigorous process for PLBs (Personal Locator Beacons). Visual inspection → Self-test → Faraday cage → Frequency analysis → Battery replacement.
The result? Guaranteed performance for the entire life of your new battery.
