ACR ResQLink 400 PLB: The Ultimate Lifeline

By Captain Mo

Updated: March 30, 2026

Mo's Bottom Line (BLUF)

If you fish offshore, this is the most important piece of gear you can buy. It sends your exact GPS location to search and rescue satellites instantly.

Taking The Search Out Of Search And Rescue

VHF radios have range limits. Cell phones are useless offshore. When disaster strikes, the ACR ResQLink 400 is the device that guarantees the Coast Guard knows exactly where you are.

The Good, The Bad, and The Salty

It requires no subscription, the battery lasts for years, and it's small enough to clip to your life jacket. The GPS acquisition is incredibly fast. The only downside is that the battery must be replaced by the factory when it expires, which is an added cost down the road.

Captain Mo's Verdict

I won't run offshore without one of these on my person. It's the ultimate insurance policy. Buy it.
