Stay Safe at Sea: The Benefits of the ACR ResQLink AIS (PLB-450)

When it comes to life on the water, preparation is everything. Whether you’re sailing offshore, fishing with friends, or heading out solo, the unexpected can happen in an instant. That’s why carrying a Personal Locator Beacon (PLB) can make all the difference.

The ACR ResQLink AIS (PLB-450) is the latest evolution in personal safety technology, offering boaters and adventurers peace of mind through a unique combination of global and local rescue systems. Here’s why it stands out as one of the most advanced PLBs available today.

Dual Signaling: Global Reach + Local Response

The PLB-450 is the world’s first PLB to combine satellite and AIS distress signaling.

• Satellite distress signal (406 MHz): Connects to the worldwide Cospas-Sarsat network, alerting international Search and Rescue (SAR) authorities.

• AIS Man Overboard (AIS MOB): Sends a direct distress alert to nearby vessels equipped with AIS, making you visible on their chartplotters and increasing the odds of rapid recovery.

This redundancy means you’re covered globally and locally, no matter where trouble strikes.

Faster Rescues with AIS Technology

Time is critical in a man-overboard situation. The PLB-450’s AIS transmissions make you an instant target on AIS-equipped vessels’ navigation screens within a 5-mile radius. That means boats closest to you can respond immediately—often much faster than waiting for coordinated SAR teams.

For coastal cruising, offshore passages, or busy waterways, AIS can mean the difference between minutes and hours in a rescue scenario.

Peace of Mind with Return Link Service (RLS)

One of the most reassuring features of the PLB-450 is its Return Link Service.

When your distress message is received by satellites, the beacon flashes a blue confirmation light, letting you know help is on the way. In stressful moments, this confirmation can ease panic and give you confidence to conserve energy while awaiting rescue.

Advanced GNSS Positioning

Unlike older beacons that rely solely on GPS, the PLB-450 uses multi-constellation GNSS (GPS, Galileo, and GLONASS). This ensures faster location acquisition and more accurate positioning—even in challenging environments like offshore storms or when surrounded by cliffs.

Smartphone Integration for Easy Checks

The PLB-450 includes NFC (Near Field Communication). With a quick tap of your smartphone, you can:

• Check battery life

• Review test results

• View activation history

• Confirm GNSS test locations

This modern convenience makes it easier to maintain your device and ensure it’s ready whenever you need it.

Built for Marine Safety

The PLB-450 isn’t just about advanced technology—it’s designed with boaters in mind:

• 121.5 MHz homing signal helps rescuers locate you once they’re in range

• Bright white and infrared strobe lights improve nighttime and low-visibility detection

• Compact and lightweight, easily attached to a lifejacket

• Waterproof and rugged enough for harsh marine conditions

Endurance You Can Rely On

• 24+ hours operational life once activated

• 5-year battery replacement cycle (6 years from manufacture)

• Regulatory approvals worldwide (Cospas-Sarsat, FCC, RED, Canadian approval)

This durability means you can trust your beacon to work when you need it most.

Why Choose the PLB-450?

The ACR ResQLink AIS (PLB-450) is more than just a beacon—it’s a comprehensive marine survival tool. By combining global satellite coverage, instant AIS visibility, return signal confirmation, and smartphone integration, it delivers an unmatched safety package for anyone spending time on the water.
