Our Verdict

The word SPOT, as it pertains to wilderness travel, has become synonymous with emergency communications. This satellite messenger is handy, compact, and proven in its value and limitations. It is an excellent tool and a reasonable value. However, competitors have closed the gaps on either side, bringing greater functionality for only slightly more money on one side, and bargain basement emergency communications on the other. Carefully read the complete review to make sure it's the best choice for your situation. The other devices we have reviewed have significant advantages over this particular, now-classic product. While it worked in our tests and the SPOT website says it has aided in over 5,000 rescues, we found it to be not nearly as reliable or feature-rich as the Garmin inReach Mini, which won our Editors' Choice award.

Our Analysis and Test Results

The third iteration of the venerable SPOT device, along with its proprietary satellite messaging service, is a simple, clear, and largely reliable way for a wilderness traveler to send rudimentary communications to the outside world. There are nuances, with preprogrammed messages and tracking and SOS capability, but it is a basic a tool to access a network to send information out of the wilderness.

Performance Comparison

Overall, with its compromised set of features, the Gen3 comes out right in the middle of the pack. Some devices do more, for a little more money, and some devices do the same important things that the SPOT does at a much lower overall cost. For many, though, the SPOT's set of attributes and functions hits the sweet spot.

SOS Emergency Messaging

The Gen3 has a clear and easy-to-use SOS button. Activating this feature sends your location and an alert, via satellite relay, to SPOT headquarters. From there a team of Search and Rescue dispatch experts works to secure the help of resources local to your position. This service is crucial, and this is what the SPOT device does. It requires a subscription, and responsible backcountry travel demands that you understand the realities of local, on-the-ground emergency response.

The SPOT Gen3's SOS button has a protective cover  but it's really easy to brush aside. If you activate it accidentally  just press it again until the light blinks red.

The message will get out rather quickly, often in a matter of minutes. However, wilderness SAR response rarely occurs within an hour and — depending on weather, terrain, socio-political issues, economic factors, and cultural limitations — it could be days, if not weeks away. Activating a SPOT device's SOS mode in Grand Teton National Park (where, incidentally, our lead test editor interviewed SAR experts on the function of various emergency location and notification products) will result in very different response time than in high-altitude South America. Your SPOT device and service is good at getting word out, but it can't circumvent the realities of remote emergency response.

It's worth reiterating directly, all the functions of the SPOT device, including SOS, require a subscription, activation, and appropriate configuration.
In addition to the SOS function that sends a message to professional dispatch, the Gen3 also features a Spot Assist button that notifies your contacts that you are in a non-life-threatening situation but need help. You and your contacts should agree, before you head to the wild, the parameters around your use of the Spot Assist mode. You can also subscribe to a version of the SPOT Assist program that will send your message to land or marine-based assistance services. This would, in theory, be used in an out of gas in the desert situation instead of an arm crushed under a rock in the desert situation.

Even with the "SPOT Assist" mode as an option, the device's emergency messaging is rudimentary. Those responding to an SOS message must assume the worst.

The ACR ResQLink+ and Ocean Signal rescueME PLB1 are a little simpler than the SPOT. All that these two products do is to send an emergency SOS message. They do it with a free registration instead of with a paid subscription, but the information transmitted is identical. The Garmin inReach explorer+ has the same emergency messaging capability as the SPOT, with the additional (and significant) advantage of being able to send, receive, and respond to actual text messages for transmission of more nuanced emergency information.

The Gen3 has three non-SOS functions that are activated by buttons along its bottom edge. From left to right they are the custom message button   automatic tracking (marking your location every 2.5 to 60 minutes)  and the check-in button. Each blinks green when activated.

Non-Emergency Messaging

The Gen3 offers rudimentary non-emergency messaging. As mentioned above, there are two degrees of emergency messaging. The third mode of messaging is the "Ok" message. You can preprogram the text of this message, and you can determine where that message is sent, as long as you have an internet connection. You can set it up to send via SMS, email, and to certain types of social media. This also needs to be programmed while still in civilization. Once in the field, you simply press the "OK" button, and it transmits whatever message and delivery options you programmed.

There is also a helping hands or S.O.V. (Save Our Vehicle) function. It alters friends or professional services that you're in a non-life-threatening situation but still need help.

We found that about 70% of these OK messages made it to their recipients. Because of this attrition rate, repetition is important, and your loved ones should thoroughly understand the device's function. As with any of these satellite communicators, agreeing with your contacts at home that "no news is good news" is the best idea.

Finally, the fourth type of messaging available from a SPOT device is its tracking mode. This is something that can be programmed and then allowed to passively send your position on some pre-set interval to SPOT's public or private web interface. Your contacts can be apprised of this tracking in a variety of ways. For some, this is an important attribute. Our test team finds it interesting in select circumstances, but it is largely a non-factor in our use.

The Ocean Signal rescueME has no option for non-emergency messaging. The ACR ResQLink can be configured, with an inexpensive subscription plan, to send a sort of non-emergency messaging. You should read the review for a full explanation. The two-way non-emergency messaging of the Garmin InReach Mini truly sets it apart from the SPOT and all the other devices. The GoTenna Mesh only does non-emergency messaging. Range and coverage are limited, but for direct communications between those in proximity and without cell signal, it's worth considering.

The Best Buy Somewear Global Hotspot offers all the perks of the SPOT Gen3, plus a larger network and two way messaging. And over the course of 5-years, the costs are essentially the same. Not long ago the SPOT Gen3 was a bargain choice, but it is now surpassed by competitors with more features and functionality for the same price.

Signal Coverage

The SPOT device you might carry is only part of a much larger system. When you send a message from the SPOT, whether that message is the SOS variety or not, it goes to the outside world via the "Globalstar" satellite network. Contrary to how it sounds, the Globalstar satellite constellation is not global. Consult SPOT and GlobalStar's documentation to see where coverage exists and to see if it might matter for you. For many adventurers, Globalstar covers all you might need.

Also note that, just like all satellite communications, the SPOT device's "view" of the sky is critical. Local vegetation, terrain, and electronic interference can impede the transmission of SPOT messages. This is the same for all satellite communications. In a specific place and time, since the respective satellite communication networks use satellites located differently and moving at different rates, one device and network might work slightly better than another.

Over the course of our testing, the SPOT completed about 70 percent of the message-send attempts. The Gen3 on the Globalstar network consistently took longer to send messages than the inReach, which operates on the Iridium network. Whether this was a question of device functionality (the inReach transmits at 1.6 instead of 0.4 watts for the Gen3, for instance) or satellite coverage, we don't know.

The inReach, ACR ResQLink+, and Ocean Signal PLB1 all use global satellite networks. They have greater coverage than the SPOT. The GoTenna Mesh has far less signal coverage.

Ease of Use

When you receive your Gen3, the instructions make it clear that you will need to buy a subscription for it to work. The setup process was relatively painless. Create an account, pay, and activate. You have several service options — see the specs for details. An important step, which should be an ongoing dialog, is to inform your contacts in civilization how to respond to the various types, timing, and potential lack of messages from your SPOT. Again, we recommend a "no news is good news" approach.

Once configured, paid, and activated, your SPOT is easy to use. Depending on the agreements you have with your contacts, you might leave the SPOT in your pack for days and weeks and years with no use at all. If you wish to use it for non-emergency messaging, there is some set up you must do at home. If you wish to use the tracking function, there is even more configuration you must do. With tracking especially, mind your battery life.

For emergency-only use, the SPOT is only a little more complicated than the ACR and the Ocean Signal. The complications are in the setup and maintenance of the paid account. For non-emergency messaging of all kinds, the SPOT is simpler than the inReach and the GoTenna Mesh.

The SPOT comes with a velcro strap that can be used with the included carabiner  as shown  or strapped directly to a bag or bike.

For what it does, the SPOT is tiny. For many years now people have carried the SPOT on adventures of all kinds. It could get a little smaller and lighter, but it is hard to imagine a device like this cutting a major percentage off.

It is the same weigh and dimensions as the Ocean Signal PLB1, but it does much more. The ACR ResQLink is twice the size of the SPOT and has fewer functions.

Best Applications

Widespread use of the SPOT family of devices has made the product and service a sort of industry standard. Some options are much less expensive (overall one must consider initial purchase and subscription costs), and others do a great deal more, but the SPOT might be the sweet spot for you.

What it does, basically, is send rudimentary messages that tell your loved ones "I am ok and I am right here", and give you the option to send notification of a dire emergency to a professional dispatch office. That is all.

While the device isn't that expensive  keeping the subscription current isn't cheap.

Emergency communications can save lives. The capability to do so is virtually priceless. That said, you've got options. The SPOT device strikes a balance. The technology and subscription service combine to hit the "middle of the road." The device itself is one third the price of the Garmin inReach, for instance. It is also quite a bit less expensive than the ACR and Ocean Signal.

Beyond that initial purchase price, though, there are subscription costs to consider. The ACR and Ocean Signal devices require no subscription cost at all. The initial purchase price of the Ocean Signal is almost twice that of the SPOT. But, over five years, the SPOT device and service will cost more than four times as much.

Allow us to make another comparison, over that same five year period. (Allow too that subscription costs can change.) When you compare the SPOT to the inReach, you find interesting results. At initial purchase, the inReach is three times the cost of the SPOT. But the inReach has the least expensive subscription plan of each, so over five years, the cost is the same. The inReach is 1.7% more expensive over five years. For that additional $20 you get the significant upgrade to two-way messaging.


The SPOT Gen3 is an iterative refinement of a proven and well-regarded product. As an early leader in the field, the brand, the product, and the service have traction. However, other products are surpassing the SPOT. It still fills a niche, but critical examination of your options is important.
