Updated Fall 2017
SPOT has changed their pricing for good and for bad. SPOT now has a rental plan: $75 for three days and $15 each additional day. It's the least expensive option for anyone that only needs a device for a week or two over a few years. Sadly, SPOT now slides an annoying extra $15 "Network Maintenance Fee" into their annual plan which seems like a deceptive way of "not raising their annual plan". This means the InReach is now roughly the same price for annual tracking but comes with the massive advantage of optional 2-way messaging. We detail below what option costs how much per day below.
Best Overall Messenger
Garmin inReach Explorer+
Easy one-handed SOS operation
Awesome two-way messaging
Smartphone interface works well
Pairs automatically on startup
Expensive up front cost
Largest of the devices we tested
This is an exception to "you get what you pay for": The Explorer+
is not only the best, but sometimes the least expensive messenger option. It's the best device for sending and receiving messages. It's expensive up front, but worth it. If there are concerned people who want to track you, this device is by far the most reliable. The InReach models are the only devices that reliably let you communicate two ways. We especially like the unlimited text messaging plans that let you message much easier and cost effectively than a SAT phone. If you don't need weather reports, a barometer or as much on-device mapping, consider the Garmin InReach SE+ and save $50.

Least Expensive for Shorter Trips
SPOT Gen3 Satellite Messenger
Lightweight and compact
Lower up front cost and rental option
No 2-way messaging
Plans can be more expensive than Garmin
The SPOT Gen3
does not support two-way messaging like the Garmin InReach
. However, it's much smaller, lighter, and is much less expensive up-front. It's also much cheaper if you only need a device for a few days a year and don't mind renting it. However, if you are only tracking or you only plan to use your device for one or two months a year, either InReach device is less expensive and gives you the option of two-way messaging.

Top Pick For Emergency Use
ACR ResQlink 406 Personal Locator Beacon
Dual frequency SOS transmission
COSPAS/SARSAT is very reliable
No annual fees
Easy to operated one-handed (even while wearing gloves)
If messaging is not important to you, and you just want an emergency signaling device, the **ResQLink is your best option. It's a little expensive up front, but there are no annual fees or plans to subscribe to. It's also much smaller than the Garmin devices. That said, you don't get the piece of mind of being able to confirm, by a message, that someone has received your distress signal.

Analysis and Test Results
Before reading further, we encourage you to read our How to Choose a Personal Locator Beacon or Satellite Messenger
, which explains the different satellite networks and how they interact with the devices we tested and our How to Best Use Your Activity Tracker and Handheld GPS Article
to see how you can get the most out of your device.
We start by asking and answering three key questions:
Will it successfully transmit an SOS when you most need it to? What if you are unconscious?
For SOS functionality, the long track record and dual transmission power together with the COSPAS/SARSAT satellite network make the ACR ResQLink the clear winner, and virtually any PLB will perform better in this capacity than the SEND devices we tested here.
However, there is a possible theoretical advantage for devices that offer tracking (SPOT Gen3
and InReach Devices
). In the case of our lead tester, if he's biking, he initiates tracking before descending. In the event of a crash in which he loses consciousness, there is still a chance that he can be found without having to press the SOS button. However, there are two major caveats here:
- If he crashes in dense trees or a canyon and ends up lying on his device it very likely will not work (based on our testing and many reports from friends and user reviews). The device manufacturers are serious when they say "Give clear view to the sky" in the manual of each device. Even a small amount of backpack material or light forest coverage can prevent a successful GPS coordinate lock.
- In this case, someone else must immediately recognize that you're in trouble and then get the coordinates from your shared map page and organize the rescue.
Is it easy to use? Can anyone pick it up and use it if needed?
Of all of the devices, the ACR has the clearest and simplest instructions for initiating an SOS. The SPOT Gen3
comes in second place here for simplicity, but the InReach has the most thorough instruction label on the device. The SPOT Gen3 Satellite Messenger
has no instructions on the device (you would have to print instructions and keep them with the device).

How Good is The Messaging?
If messaging is the most important feature for you, the Garmin InReach
is by far the winner and beats the SPOT Gen3
by a large margin. If you want the ability to send one simple pre-defined check-in message with no guarantee the person got the message, then the SPOT Gen3
gets the job done. For tracking, all three of the above devices functioned reasonably well, with the InReach
So let's look at some real world needs and situations
- Ability to track a family member on a backpacking trip: both Inreach and SPOT work about the same. However, if you're using the SPOT incorrectly or there is some other technical issue, the person following you has no way to check in if they see you stop moving on the map
- You're backpacking buddy severely sprains his leg five miles from the trailhead and can't walk out — This is where the InReach shines. You could notify friends of the injury and coordinate the proper level assistance from Search and Rescue. With the SPOT, you could only signal an emergency and would not know if a rescue was coming or if you requested "too much of a rescue." For example, your SOS distress signal could be interpreted needing a helicopter which might leave you with a $100,000 bill when all you needed was a basic splint and a few people and a wheeled litter to help you out.
- Your car breaks down on a remote road out of cell phone range — like the above situation, you only have two options with the SPOT: call a rescue or, set a preset message to say "Car broke down — need help." Again, since there is no way to confirm someone got your message with the SPOT, you would anxiously wait a while and hope. With the InReach, you would be able to communicate and arrange the appropriate amount of assistance. SPOT offers a S.O.V. (Save Our Vehicle) program that you can add that starts at $30 per year.
In summary, the InReach bills itself as a "2-way satellite communicator" and it lives up to its title. You can indeed communicate via satellites and it also, on the side, has as SOS feature. The SPOT is more of an all or nothing device: either people are watching you, you can engage in simple one-way communication, or you are calling in a rescue.
Garmin Buys DeLorme: Differences between the Garmin InReach and DeLorme Inreach
- Garmin version has a much larger screen — 1.75" x 1.5" vs. 1.4" x 1.2"
- Delorme power button is easy to accidentally press — must press another button to turn on, this makes it mostly safe from accidentally being turned on
- Same on-screen menu, Delorme has a social media button instead of a weather button
- No weather forecast on Delorme
- Garmin inReach Explorer+ can get a 3-day weather forecast that is updated via GPS location
- both should be supported for many years to come
- both use the same operating system
- both acquire satellites and send messages at the same rates
Reception: Experience in the field: SPOT Gen3 vs. Garmin InReach
We used the SPOT Gen3
side-by-side with the Garmin InReach
throughout the test, recording the time needed for standalone messages to be received by contacts and confirmed as sent. The InReach messages were received faster than the SPOT messages about 60 percent of the time, with the InReach messages either confirmed as failed or received within 20 minutes almost every time. The SPOT messages at times confirmed as failed only 45 minutes after the send attempt, and were sometimes received more than two hours after the initial send. Testing these two devices side-by-side in stand-alone mode is the "apples to apples" test, but it's only fair to mention that the InReach, when paired with a smartphone, allows the user to watch the progress of the message send on the phone with a clear visual confirmation of it being sent successfully or not. This is a lot nicer than trying to decipher the blinking lights on the SPOT, wondering if the message was sent or not. Since the chief feature of the SPOT is its ability to send messages to your contacts, and the InReach performs message sending so much better, the InReach is quite clearly a superior device for this purpose.
Example of the InReach messaging when paired with a smart phone.
A common anecdote illustrating a drawback of any satellite messenger device which performs with less than 100 percent consistency is that if your contacts are expecting to receive "okay" messages from you, then not receiving them is almost a guaranteed source of stress. If your family or significant other is expecting to receive "okay" messages at a particular frequency, and then they do not, it could cause them to raise the alarm unnecessarily. Indeed, there are many reported cases of this documented by rescue services and many stories of a messaging device causing, instead of alleviating, stress for people who are tracking the progress of the user.
If you are using a device to reassure your contacts that you are okay on an hourly/daily basis, then be sure that everyone fully understands the limitations of the device and establish a clear understanding of what it could mean if the messages are not received.
Comparing Plans: InReach Now Cheaper in Most Scenarios
It used to be the SPOT had a much less expensive data plan. However, InReach now has a Freedom plan that does not require an annual subscription (SPOT requires a 12-month commitment). For people who only make a few trips a year out of cell service, you save money with the InReach plans, even with unlimited texting at the $65 level. Over a few years, it could be cheaper to own the InReach despite it costing $400 compared to the SPOT's $165 price tag. It all depends on which service plan you choose so every situation is different.

Some Typical Scenarios and How Much Plans Cost
Unlimited Tracking Per Year
InReach: $169 ($144 in monthly fees + $25 activation)
Tracking for One Week
SPOT: $165 (unless you rent the Spot, in which case it's $75 for 1st 3 days and $15 each additiona day)
InReach: $40: $15 + $25 annual fee
Unlimited Messaging for One Week
SPOT: $165 (unless you rent the Spot, in which case it's $75 for 1st 3 days and $15 each additional day)
InReach: $90: $65 + $25 annual fee
If you need the device for more than one week a year, the InReach becomes drastically less expensive than the SPOT.
How Does the InReach Compare to Satellite Phones and Satellite Internet Hubs?
In brief: The InReach is a bargain and much more reliable. Satellite phones are much more expensive than satellite messengers and satellite internet hubs are drastically more costly.
Satellite Internet Hubs
From left to right: iSavi Internet Hub, inReach Explorer+ and Globarstar Satellite Phone
— These claim to offer a wifi hotspot anywhere and the ability to check your email, run apps, and send texts. A popular model is the iSavi IsatHub
that retails for $1200. Expensive, but nothing compared to the insanely expensive data plans: it costs $600 for 100MB of data (most cell phone plans cost $1 for 100MB). A less expensive option is the Iridium GO!
for $799. But again, the minutes are expensive: a prepaid card for 500 voice minutes and 3000 text messages is $725. We have not tested either unit, but the user reviews on numerous web sites leave us concerned about the ease of use, connectivity issues, and data speeds. Compare that to the InReach which has relatively minor connectivity problems and gives you unlimited text messaging for $60 a month. We want an affordable and reliable way to browse the web by satellite when deep in the backcountry, but we just are not there yet.
— prices and performance vary widely:
- It's about $300 and $0.60 a minute for a phone on the GlobalStar network (same network the SPOT uses).
- It's about $700 and $1.00 a minute for a phone on the Inmarsat network.
- It's about $1,000 and $2.00 a minute for a phone on the Iridium network (same network the InReach uses).
With SAT phones, you get what you pay for: the more expensive messengers on the Iridium network have fewer connectivity issues and greater coverage. But even the Iridium network can be spotty. Be ready to wait a few minutes for a connection and don't be surprised if calls drop. The beauty of a satellite messenger like the InReach is that you compose and send your message and then forget about it. The message sends immediately or within a few minutes when it connects to satellites. With a SAT phone, on the other hand, you have to sit there and stare at the screen, sometimes for 10+ minutes, and wait for connectivity, then quickly place the call and hope you don't get dropped.
In our experience, a good satellite messenger is dramatically less expensive, and less frustrating to use than a SAT phone or a SAT internet hub. We hope we have been able to help you decide if you need a personal locator beacon or satellite device and if so, which model is best for you. However, if you're still undecided, consider reading over our buying advice
