For those times when yelling 'Here I am' and flailing your arms won't get the job done.

Once upon a time, suffering a broken femur during a solo backcountry trek meant that you were a goner, but thanks to the ACR ResQlink 406 Personal Locator Beacon, that no longer has to be the case. This high-powered emergency locator and GPS integrates three levels of signal technology so that you can always send out a distress signal to SAR teams regardless of your location on the planet.

  • Its 406 MHz signal relays information to the worldwide SAR satellite network
  • The 121.5 MHz signal relays your location to localized ground Search and Rescue operations
  • On-board GPS accurately notifies rescuers of your position and is accurate to within 100 meters
  • Bright LED strobe light is automatically activated when rescue signal sent
  • Full-function test mode lets you know it is working properly without draining the battery
  • GPS acquisition test mode allows you to test GPS functionality up to 12 times over the life of the battery
  • Small, lightweight, and easy to carry in a pack, pocket, or on the included lanyard
  • No subscription or activation fees required, but the device is compatible with the optional subscription service, so you can send periodic 'I'm OK' messages to family
  • Note: device does not float; for a similar device that floats, check out the ACR AquaLink PLB

Here's what others have to say...


peace of mind

  • Familiarity:I've used it once or twice and have initial impressions

My son is going on his 1st solo hike we bought this for him to have piece of mind. The reviews sold us on this one.


Peace of mind in a tiny package

    Pretty much any question can be answered by the manual which can be downloaded here: I liked that a self test could be performed (fast & easy - page 12 of manual) to prove it's in working order. Kinda hard to give a product 5 stars not having used it but the self test feature pushed it from 4 to 5 stars for me. Also worth checking out the ACR website for stories of people who have had to use it. Everyone seems to ask about messaging...There is no texting or message feature as with the SPOT and other PLB's but the ResQLink is far more powerful than SPOT as well as being much smaller. Those were the 2 deciding factors in my decision to buy this one over the other options. Ease of flip the antenna up, hold the button for one full second and you're done. A red light flashes every 3 seconds to let you know it has been activated and then the red light is replaced by a green light to let you know your GPS coordinates have been downloaded and your SOS is being transmitted.


    ARC won't honor PROMO

    • Familiarity:I gave it as a gift but have feedback to share

    ARC Artex will NOT honor their promo deals if you buy from Amazon. Why? I was told that "due to the substantial savings" I already received from Amazon, I didn't qualify for the promo. How much did I save? ONE CENT ! I paid $239.99 and to get the $140 promo, I had to pay $240. Yes, a single penny! They don't tell you this outright, but bury it in an attachment. You don't know this until they turn you down for your promo deal. Also, they delete any warning or negative comments on their FB page, then block you from reposting. Nefarious and untrustworthy!?

    You should contact Amazon about it, if you haven't already. Amazon is very good about taking care of customers. It wouldn't surprise me if Amazon tried to make right for you somehow. They have for me in the past, on other things.

    Oh... And, one more thing... Thanks for your review above! I was in the market for a new PLB. I was considering this or the McMurdo Fast Find 220. Based on what I've recently read of ACR reviews, and most specifically your review this morning, I ordered a McMurdo right before lunch today instead of the ACR! :-)

    The last time I bought an ACR COSPAS SARSAT PLB (acronyms, anyone?...) It was more than double the size of this one, double the price and double the weight.

    I'll post a pic...

    There were times when I would look at my pack...look at the PLB...look at the pack...and ditch the PLB. (Gotta make room for my DSLR and 3 lenses, after-all...priorities...)

    That won't happen with this one. It's so small, it falls into the "negligible" category.


    Does anyone know the price associated with...

    Does anyone know the price associated with the battery replacement? I understand it must be replaced every 5 years by the company but I can't find the price anywhere.

    I would contact ACR directly. I have heard it is between $100 and $200 but that was a quote on a more expensive model so I would think for this it would be closer to the $100.

    The battery canbe replaced by anyone. In the old ones it just plugs in. They use two battery's ,each one is made up of two cr123a battery's that are attached and wraped


    Simple & Small

    • Gender:Male

    It's hard to give a review on a PLB without actually having used it. But from the perspective of design, this thing is great. It's small and simple; great to carry and simple to use--very important. Instructions on how to use the PLB is also printed onto the beacon in case you're panicking.

    I would recommend you buying this just for the peace of mind of yourself and your family back home.

    You Use It...We replace t

    You Use It...We replace t

    ACR has just annouced the creation of, a complete program where they will replace any 406 MHz PLB (regardless of age) with a brand new beaon. Learn more at

    Does this imply it's a 'one time use'? If you trade in a 'used' one for a new one?

    It kind of is, the batteries are designed to only run for about 24 hours once you hit the SOS. So at the very least they need to be replaced after using it. But like it says ACR will replace it if you have to use it, which is a great deal. And it's really only trading in a device used to save a life.

    Our ACR Personal Locator Beacons are not one time use, you can have the batteries services on these units. Pgunnz is correct, that after an emergency activation, you do need to have the batteries replaced. Our new SurvivorClub allows you to exchange your beacon for a new Free Replacement if you share your story on our website so that others can learn from your experience. If you don't want to share your story we can always assist you in getting your battery replaced so you can continue using (or hopefully not using) your beacon.


    So small

      Just got my Resqlink from and wow is it small and light. So much lighter and smaller than both my SPOT (1st version) and especially my ACR AQUAFIX (2006 model). Bought the Resqlink because it was cheaper than replacing the 6 year old battery in the Aquafix. Now I will carry the PLB with me on all adventures. Used to leave the Aquafix at home because it was too big and heavy to lug around. It is even smaller than my Spot which wouldn't be as effective in a real emergency anways. And no subscription fees also. Win win win.

      What is the difference between the ACR SARLink 406 and the ACR ResQlink 406? From the product descriptions i can not tell any difference except for about $100. Thank you.

      Hey John,

      The initial signal goes out to the satellite using 406 MHz, localized ground and air rescue then track your location to a much smaller radius using 121.5 MHz. This device transmits a signal only, no voice communication.

      Does this unit have batteries that I can replace or do I have to return it to the manufacturer to have batteries changed? I would not buy a unit that did not have batteries I can change.

      Best Answer

      No you can't, ACR has approved replacement techs. Check on ACR's website or Facebook page and they'll give you a more detailed reason, but basicly it boils down to the fact it is a lifesaveing device and they go over the unit and replace the seals when they replace the battery.

      The batteries last for 5 years or one rescue, whichever comes first! I read it's about $160 to have the battery replaced. And there's no subscription fee.


      Finally its pocket sized

        First let me start by saying that I do work at ACR, but I am also an avid outdoorsman and I am absolutely loving the new ResQLink PLB. Previous PLB's that I have used were always a little too big to simply carry in my pocket and my fear was getting separated from my backpack should I actually need to use it. I finally got my new ResQLink last weekend and I tossed it in my jean pocket and headed out for an afternoon hike around the ranch. It fits perfect, about the size of a 2005 flip cell phone or powerbar. If anyone else has one let me know what you think or if you have any questions I can answer for you. I am a pretty conservative hike, but the peace of mind I have knowing should anything go wrong is well worth the price.

        I am looking for something with backtracker as well as the emergency gps. Do you know of something or will this do that. I worry about my son getting lost as well as injured.

        You want something like the SPOT or inReach that offer tracking and message functions as well as SOS. Both of those units require subscriptions on top of the cost of the device itself.

        Took a little hike at the ranch this past weekend with my new ResQLink PLB. Fits perfectly in my day pack.
