What Are Buyers Saying?


The first personal locator beacon we examined is manufactured by ACR- it's the ResQLink. When you buy this particular option, it arrives programs with US country codes- this means that while it will work internationally, the primary authority that will be alerted in an emergency is actually the US Coast Guard agency that the beacon is registered with.

You can actually contact the manufacturer prior to purchase if you want it to be configured and registered with a different country. It's essential that you register your beacon- in many countries, this is actually a legal requirement because once it's activated this information is crucial for search and rescue teams to be able to locate you.

A satellite-enabled a notification device, this option doesn't require recurring payments in the form of annual or monthly subscriptions to function. It only weighs 5.4 ounces, floats, and is marketed as one of the smallest personal locator beacons you can buy- easily fitting in your pocket. It's marketed towards pilots, boaters and people who enjoy water sports.

The way it works, whenever it is activated it employs GPS positioning and signal technology to relay your exact position to search and rescue satellites. The battery itself is engineered and should last for six years and they say has an 11-year shelf life.

  • One buyer tells us that he uses this option tied to his life vest- this means that if he ends up overboard in the water he'll be able to activate it.
  • Buyers also say that the unit is designed to be activated once and then you'll have to service it- obviously intended only for emergency use.
  • One hiker tells us that it needs to be registered with NOAA. Buyers are careful to warn that it needs to be activated only in emergency situations.
  • One reviewer says that the company will replace your beacon if it's employed in a life or death situation. Indeed, besides just in ocean-faring situations, buyers are also campers and hikers that voyage deep into the wilderness for extended trips.
  • Another buyer tells us that his family enjoys adventure travel and praises the beacon for providing them some peace of mind when traveling in remote locations.
  • All you have to do to activate it, he tells us, is flip up the antenna and then turn the device on.
  • Another buyer actually had the opportunity to use it- he activated the signal after his boat capsized in the ocean, the Coast Guard contacted his wife within several minutes to verify that he indeed was actually out on the waters, and a helicopter was quickly dispatched.

The Spot

The third beacon we examined is the Spot Personal Tracker- it's marketed towards buyers on adventure trips and it does require the purchase of a service plan. This device is a little bit different than the previous two- it enables you to allow family members and other contacts the ability to track your location in non-emergency settings.
