ACR ResQLink 400 - SOS Personal Locator Beacon with GPS (Model: PLB-400) ACR 2921

Bought for hiking and was happy with the unit. Until I went to test and it failed the battery test. Had to drive two hours to the nearest authorized battery replacement dealer; informed it was not the battery, I needed to contact the company about warranty. Good luck! Customer service sucks...if you can even get hold of someone!

But also make sure not to confuse the manufacture date (to the immediate right of the uin and in black on white) with the battery life (black on yellow)....wasnt very visible when I went to register the product. If you register any product ever, this is one not to skip. You might not know what kind of product you have. They changed the website so the warranty registration was under a link leaving me to wonder how current the product was. Glad to find out it exp in 2026, not 2020

This will SAVE YOUR LIFE !!!

It appears to work fine. Hopefully I will never have to test it for real. All the setup and registration was easy and worked flawlessly. All the self test checks worked with no problems.

Getting it registered wasn’t easy but not the fault of Amazon or the company that made it.

Very good experience. Arrived on time great price. Easy to understand how to use it. I go offshore and it adds another level of safety

Great for peace of mind. Anywhere in the world, any time, you’ll be found if you can see the sky. So please don’t activate it indoors, it must see the skies to see the satellites. As for the guy who strapped it to his jet ski, this made is for terrestrial endeavors. And while it will float, it’s only made for water pressures found at the water surface. They have beacons for marine use. You might as well complain about your jet ski conking out when riding on land. Pick right tool for the right job.

I can only really give it Zero Stars. A review for something I have not used is no review at all. Its nice looking and small. The Test Button works and the antenna deploys. If I ever use it, I will follow up on this review with my experience.

I cant comment on how it works because to test that feature would cost several thousand dollars after paying rescue teams. However, I have no reason to believe that it wouldnt work. It is obviously very high quality. NOOA registration is a requirement as, once initiated, NOAA handles the actual rescue process. No registration, no rescue. I carry with me on all my hiking trips.

This is my second PLB from ACR. I still have my first in my sailing bag but, this one is for Winter travel. I drive all accross Washington, Oregon and some of Idaho. Once your away from cities, cell phones become less reliable. I have whitnessed some really terrible accidents in pretty remote areas. This PLB is my Just In Case back up.
