Safety first and safety always, especially for frequent travelers, hunters, hikers, anglers, or any outdoor aficionados. This is one of those items that is better to have and hopefully never need, than to need and regretfully not have. NOAA registration is quick and easy. Protect yourself, protect your loved ones. This is an exceptionally made safety device and should be considered as essential gear for all outdoor adventure enthusiasts. Peace of mind is priceless.

Actually I hope never to use it, but if the need arose I suspect this unit would be helpful. This replaces a McMurdo Fast Find which I've had for 8 years and never used. The battery in the Fast Find still shows full charge after all these years, but I thought it best to replace and upgrade. Both are fine units, I just appreciated the longer signal life on the ResQLink. The only downside is the belt clip is close to impossible (don't give up) to attach to the unit and for all the trouble the closure on the belt clip is too wide and doesn't stay on your belt or pack. Also, the antenna can and does deploy when thrown in a bag or pack. Not a big deal, just an inconvenience.

Purchased for mountain hiking trip (Colorado 14ers) but discovered TSA waffling on airline carriage allowability.

I love that I don’t have to buy a monthly subscription for this as it only gets used for part of the year (hunting season). All of the setup and registration was clearly outlined in instructions. It’s smaller and lighter than I expected which is nice as my pack already feels heavy enough! Happy with my purchase.
Great for peace of mind. Anywhere in the world, any time, youll be found if you can see the sky. So please dont 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, its 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 find this an A+ seven yr Life Insurance Policy.LIMITATIONS: This product sends a signal to a satellite in outer space which only indicates to those on the ground receiving it that you have a crisis.Rival products, $$$, Much More Expensive, will give you the ability to message personal needs, or, in less highly expensive models the owner can pick from a cache of phases---Need Gas, Snake Bite, broken bone, etc.Also, this works in the Lower 48 states USA only....no Canada or Mexico. : (
I couldn't give any stars for the battery life because I just got it , I assume it's battery will last like it says. This was very easy to register online . The instructions were very simple on how to use it . As far as I know it will work , i did run the test and it passed. Size wise it's about like a small version of the old clunky cell phones and not super heavy but heavier than the average cell phone . I'd say worth the money for the peace of mind. I think anyone that goes out on the water should have one of these . Things can go very wrong very quick.
I bought this for dual use - nearshore boating and hiking in the Whites. It does what it says it does, and it very reasonably priced. Someone is criticizing the $150 dealers charge for battery replacement. There are a lot of online dealers that will replace the long-life lithium battery in this for less that half of what an authorized dealer charges. And you really only need to replace the battery after a rescue (or 5 years I think). But consider that it needs to be kept waterproof after the battery is replaced and it is considered an FCC-registered life saving device. I pay for the dealer to do it, and this is from some someone who buys $15 Samsung Galaxy batteries on ebay and melts the back off my phone to save $20.
This review is to address another reviewers concern of inadvertent activation. Upon receiving this item I attempted to recreate this problem by using a significant amount of force pushing through the protective cover. These efforts were unsuccessful.While this unit is larger than the PLB375 it does utilize the new MEOSAR network. For those unsure of this unit versus a Garmin option, it is worthwhile to look into the various satellite networks. Multiple solutions is always best, but if it's between MEOSAR and Iridium, I'd bet my life on the former.
The USMC gave me my first one in Afghanistan in 2010, I have since when on and just bought #3 do a lot of boating on the Great Lakes and made the Miami to Bimini run on a 19ft Yamaha AR190 and a Sea-Doo GTX. Came across a family who had engine trouble and a handheld radio 30 miles out of Miami they had a Garmin PLB that wouldn’t get a signal my friends ACR got a signal within a min and USCG was on scene in about 40mins from activation, the USCG got a fishing boat to tow the family back. ACR gave him a new one due to the activation was considered an emergency. Great product wouldn’t trust any other PLB/ EPIRBs
