Full Featured – But not for everyone. Here’s an objective comparison of InReach models
There are now seven Garmin GPS handhelds with InReach messaging via the Iridium satellite network. Here is a quick listing of the models followed by a more detailed description of their pros and cons.
GPSMAP 66i – Added InReach satellite Messaging, SOS, and Weather forcasts to the already successful GPSMAP 66st. But this has the lowest battery life of existing InReach models with 35 hours under normal use.
InReach Explorer+ - The longest lasting (100 hours) InReach with 24k maps of North America and navigation built-in.
InReach SE+ - The same long lasting InReach as the Explorer+ but without built-in maps and navigation.
InReach Mini – A small version of the SE+ with half the battery life, half the size, and weight.
InReach Mini 2 - Same basic device as the InReach Mini,but with MUCH longer battery life and easy backtracking along your route to your starting position.
InReach Montana 700i/750i - Large touch screen navigator and satellite communicator. Best for Cars or off-road vehicles.
InReach Messenger - Small communication only device (No Navigation) for easy back and forth texts, emails, or SOS. Easy to carry and simple to use when paired to your phone.
First let’s get some basics out of the way. Buy this or one of the other InReach models if you expect to be beyond cell coverage. It could SAVE YOUR LIFE. The InReach two-way satellite messaging feature costs more to buy than a GPS receiver alone and requires a subscription for the messaging feature, like all utilities, phone, cable, electricity, etc. Also please realize that messaging is a two-way process. Unlike GPS which only receives location Info from satellites, messaging must send your message high into space and therefor needs lots of battery power. All InReach models will send and receive text (SMS) and email messages to anyone in the World with a phone that can get normal texts and emails. But it will take longer than Cell texting which uses a grid of towers nearby just waiting to take your message and pass it on. However, there are no Cell towers in the wilderness or out at sea. The InReach uses the Iridium system of over 60 satellites which each take about 90 minutes to make one circle of the Earth. At any time, the chance of your device communicating with a satellite depends on if a satellite is passing, how much unobstructed sky is above, and if your InReach is “Looking” to communicate. Simply put, if you want the best chance of quicker communications get into an open space where the chance of “seeing” a passing satellite or two is greater and tell your InReach to check for messages. Bottom line, messages take time to send and receive. Millions of messages and tracking locations have been successfully sent and the InReach SOS system has had over10,000 search and rescue responses. It’s very reliable if you understand how to use it properly. Your next best option is smoke signals. Please also be assured that if you carry a smartphone (iOS or Android) the included EarthMate or Explore apps will provide detailed topo maps of North America and link to any InReach model to make typing messages easy using the phone's touch keyboard. So, even if the InReach does not have BUILT-IN maps you still have it all with EarthMate or Explore on your phone without any cell or Internet connection.
I have used the GPSMAP 66i and each of the other Garmin InReach handhelds. Here are my recommendations for their best and less useful features and who would benefit most from each. My tests have shown that they all perform equally for sending and receiving satellite messages. And the cost of the messaging service subscriptions is the same for all models. Here is a list the major differences and what each means.
The GPSMAP 66i is built on the proven GPSMAP system of GPS handhelds. It uses Garmin’s system of device integration and coordination. It is the first InReach to completely break free from the original DeLorme system after Garmin took over. Read the GPSMAP 66st manual online for a full understanding of all that this system will do. PROS: Full InReach technology including messaging, SOS, and satillite weather forecasts, A larger screen. Extensive WiFi and Bluetooth connectivity to other Garmin watches, sensors, and health devices. Ability to store, classify, and share activity, routes, waypoints, and other data via the Garmin cloud. The built-in TopoActive map supports turn-by-turn prompts on the trail when using a route and has lots more short local trails than that in the Explorer+ which requires you to download additional OpenStreetMaps directly into its built-in free space or into a paired phone for more local trails. You can download directly into the GPSMAP 66i free, but poor resolution BirdsEye Satellite Imagery to overlay your topo maps with actual photo data. With the optional City Navigator North America NT map ($80) the GPSMAP 66i can be set to look and act just like a dedicated road GPS for driving. It includes thousands of points of interest (shopping, lodging, travel etc.) that can be searched and navigated to with on-road turn by turn calculation. The only features found in dedicated automobile GPS devices that it doesn’t have are voice notifications for upcoming turns (it uses tones) and traffic conditions. Even so, this lets you buy just one device that will work very well on the road as well as the trail. CONS: The BATTERY LIFE IS ONLY 35 HOURS under normal usage. This, like all InReach devices, this can be substantially extended by careful planning. But this is a poor choice for multi-day off-grid excursions due to the limited battery life. All those handy GPSMAP features take energy and many are of no use in the wilderness beyond cell or WiFi access. BEST FOR: People who like the full featured Garmin fitness and activity gear, welcome access to Garmin maps and the Garmin cloud systems, like BirdsEye photo imagery directly in the device without a phone, and don’t often venture into the backcountry for more than a long weekend. Please understand that most of the GPSMAP features beyond the InReach messaging, weather, and SOS go away when you go beyond the cell system. Most important, conserve the battery or bring along an external battery recharging pack in case of an emergency and the need to text with GEOS and rescue responders. This is Garmin's current Top of the Line GPS handheld due to its many features and InReach technology. It's a great choice for most casual hikers, boaters, and hunters.
The Explorer+ is in my opinion the best handheld for anyone who plans to be beyond Cell coverage for more than a couple of days. It will last 100 hours under normal conditions and over a month with careful planning. Like the GPSMAP 66i it has a built-in map of North America with robust navigation features. However this is NOT a TopoActive map with the ability to have turn-by-turn prompt tones like the map in the GPSMAP 66i. This unit can stand alone long after your phone dies. PROS: Long battery life, built-in 24k topo map of North America, weather forecasts from the backcountry via the satellite system. Built-in digital compass, accelerometer, and altimeter for precise location and bearing info without the need to be moving. The Explorer+ can store additional maps, contacts, routes, and waypoints internally after syncing at home. CONS: Not compatible with Garmin's fitness, exchange systems, and TopoActive maps like the GPSMAP 66i. BEST FOR: Long distance hikers, hunters, and boaters who expect to be beyond cell service for many days and want to be able to navigate without the need to use a phone.
The InReach SE+ Same size and satellite messaging as the Explorer+ but without the Map and Navigation features. PROS: 100 hour battery for messaging, SOS, and satellite based weather forecasts. Same rugged case and waterproof standard as the explorer+. CONS: Only $50 less than the Explorer+. In my opinion spending that little bit of extra money gets you a lot more value in navigation and location capability in the Explorer+. BEST FOR: Those who only want off-grid communications, SOS, and long battery life for extended use.
The InReach Mini and Mini 2 are the smallest and lightest GPS Navigators and Satellite Communication devices, but most difficult to use in a stand-alone mode. But pair it to a smartphone and you have both easy messaging with contacts, routes, and waypoints available as well as a free full features topo map of North America. PROS: Small and light. Easy to carry with you at all times for when the car dies in a cell dead zone, satellite messages, weather forecasts, and SOS. CONS: Tedious to write messages from the device. Only 50 hours of battery under normal use. This is half of the battery life of the Explorer+ or SE+. No built-in map for navigation. Must pair to your smartphone to see a map and navigate. But cell phones won’t last as long. When they lose battery, navigation goes also. The Mini although lighter and smaller will need a phone to navigate and a battery pack to recharge both devices thus adding to the total size and weight. BEST FOR: People who just want to be able to communicate from beyond cell service for convenience or safety in emergencies and like the fact that when connected to a phone running the EarthMate app it provides a great detailed map and navigation. Those who appreciate its small size and weight and don’t feel a need for extended battery life. The average day or weekend hiker, hunter, or boater who likes the security of weather forecasts in the wilderness, two-way SOS, and the ability to keep in touch with home. Anyone who wants to get help from a dead cell zone when things go wrong. Due to the greately improved battery life as well as backtracking option in the Mini 2, it is well worth the cost of above the InReach Mini. However, if you already own the Mini and only take day hikes in good weathr on popular trails, I wouldn't spend the extra money to upgrade.
The Montana 700i or 750i are specialty units designed to be used in vehicles. Their large touch screens make them easy to see and use while driving a car, motoecycle, or off-road vehicle. Maps are included for BOTH street and trail use. The 700i is full featured, but without a camera. The 750i has a built-in camera for capturing those breathtaking vistas along your journey. PROS: Very large touch screen display. Ideal for mounting on a dashboard or handlebars where the screen is farther from you face. Both on and off road routable maps. Voice responses when used with its companion mount. CONS: Large and heavy. Not advantagious for long hikes. May have some problems with thick gloves in cold conditions usinng the touch screen. Less battery life than other InReach models.
The InReach Messenger is designed for easy to carry and easy to use messaging with friends and family. SOS is also available for an emergency. This InReach does not provide navigation features. Its BIG ADVANTAGE is the new software app (also called Messenger) that it uses on you phone. When you send a message, the software determines if you have an active Cellular signal. If you do, it will send the message via the Cell system, thus saving you usage charges on your InReach satellite subscription. If there is no cell service, the message will be sent through the satellites just as all other InReach devices. NOTE: Garmin has indicated that since the ability to determine and use Cell service is a feature more of the Messanger phone app than the InReach device, they hope to make older legacy InReach devices able to use the Messanger app and use Cell service when available. So, if you like the Cell/Satellite feature of the InReach Messanger, and you also love your current InReach model, perhaps waiting for your existing model to be available to use the Messenger phone app is worthwile. However, my guess is that both the InReach Explorer+ and the InReach SE+ may not be compatable with the new Messenger phone app because they were built on the DeLorme software platform. All newer models from the Mini on have used the Garmin platform.
Which model is best for you? If you are a long distance, multi-day hiker, hunter, or offshore boater the Explorer+ or the Mini 2 are the best choices for you. Their long battery life and additional downloadable maps and NOAA charts to your phone give you everything you need for many days off grid. Keep in mind that you should plan to save 25% of your battery in case of a SOS emergency and the need to communicate with GEOS and rescue responders.
If you hike on weekends or the occasional vacation for just a few days the InReach SE+ or Mini will serve you well for messaging, satellite weather forecasts, and SOS. Remember these don’t have built-in navigation so bring along your smartphone with the free EarthMate app installed. Anyone who wants the ability to get help or just reach out to family or friends from dead Cell areas should consider the Mini. It's small, easy to carry and always there when you need it. And, an minimum Annual Subscription is well worth the peace of mind.
If you are an active biker, runner, or other sport enthusiast who spends most of the time within the Cell system range but likes weekends or a few days in the wild you might consider the GPSMAP 66i. It costs more, but it does integrate with the existing Garmin systems that support inter-device sharing, WiFi apps, and many other features that won’t work in the wilderness but are helpful when you are back in your home base. Its built-in map also has lots of short local trails without the need to add OpenStreetMaps. Its ability to use TopoActive turn-by-turn prompted maps for pre-defined routes can be helpful to insure you don't miss a vital turn. And if you need a full-featured automotive GPS navigator adding the Garmin City Navigator North America NT map ($80) will save paying hundreds for a second device.
If on and off-road vehicle adventures are your cup of tea, the InReach Montana 700i or 750i are great accessories that will let you keep in touch with family and friends and have the assurance that when things go wrong, you have a simple SOS button to call for help.
If you want the safety and assurance of always having access to ether Cell or Satellite service, an InReach Messenger along with a yearly Safety subscription is both inexpensive and convenient. The Messenger can always be with you tucked away in your pocket due to its thin and commpact shape. When used with the Messenger app on your phone, you can eacily communnicate and know that your satellite subscription won't be needed if you're in Cell range.
Final Answer… All of these InReach included devices will let you send and receive texts or emails from anywhere to anyone, get weather forcasts anywhere via the satillites, and get help for any emergency from a flat tire to a broken leg in the wilderness. They all work equally well. The service plans are priced for every budget. The cheapest plan is less than $15 per month. I pay more than that in one day for my coffee and pastry breaks. The unlimited plan tops off at under $70 per month if you want the ability to deactivate the device and not pay for the months you won’t need it. Annual Contract plans which keep the device active at all times are cheaper per month. As an example, I carry a MINI at all times on the Annual Safety plan for $13 per month. This gives me the peace of mind of knowing I can communicate when the car breaks down in a dead cell zone. GEOS will call my roadside assistance provider for me if I press the SOS button. Or I can text a family member to help. I also have an Explorer+ for those multi-day backcountry photo expeditions where long battery life is critical. The Explorer+ is on the Freedom Expedition plan at $70 per month with unlimited messages but only for the months that I need it.
Hopefully this has been helpful. Please choose the best InReach device for your needs and budget. Is it worth the cost? Consider the consequences of being unable to communicate when misfortune hits you or someone you meet on the trail or at sea. Many lives have been saved by the InReach since it was developed. No matter which choice you make remember to stop and enjoy the view.
