Rescue services have seen an increasing number of life-threatening situations caused by the unwise use of smartphones. Phones aren't sufficiently rugged and often lack user-replaceable batteries, so cannot be relied upon as a navigation tool or as a means of emergency communication.
If you're considering buying a product like this, think again. An FRS radio and a Garmin Etrex cost about the same, but are vastly better suited to the task. They are drop resistant, waterproof and will run on ordinary AA batteries.
If you are in a remote area, always carry a magnetic compass and paper map and ensure that you have the skills required to use them. Consider carrying distress flares, a signal mirror or a SPOT beacon.

Along with basic financials, I inclined to agree that'd be a very good add for required classes.
If I remember right, it was a one- or two-day field trip we took during middle school. Everyone was excited when it was their class's turn to go. (But who doesn't get excited for a field trip?)
Not as comprehensive as what you'd learn in scouts or taking a professional survival class, but it was a good overview. I still remember a lot of it and find the material useful.
This was in South Lake Tahoe CA, so we were already in the mountains. :) Cost wouldn't have been any worse than any other field trip.
I should go do some more, I'm fairly confident in my map skills but I bet there are some assumptions of mine to knock down.
It's similar to orienteering but team-based, everyone leaves en masse, and control points can be reached in any order within a fixed amount of time. This means you can be competitive by walking and relying on compass smarts rather than having to be able to run for hours on end.
This looks like a calendar of US rogaining events: http://www.us.orienteering.org/orienteers/rogaines/events
I got into it a year or two ago here in Australia and have now competed in a state and national event plus others. Entered into the world champs in July, though we will be aiming mostly to not come last!
That said: Having just done some research on distress beacons, I just want to point out that there's some better options than SPOT beacons out there.
The problem with SPOT is that they're entirely reliant on GPS and having a clear view of the southern sky. If either of those aren't met, your SOS message might not go through properly. Since folks often buy these for life-and-death situations, this is a problem.
I'd recommend an actual 406 MHz PLB (personal locator beacon). The big benefit is that these are triply redundant: GPS via geostationary satellites, doppler shift triangulation via low-earth orbit satellites, and old-fashioned direction finding on the 121.5 aircraft distress frequency.
As an added bonus, since the PLB network is run by an international government organization (COSPAS-SARSAT), there's no subscription fees either. It would be unfortunate if you didn't get rescued because you forgot to pay a bill.
The only downside is that you don't get breadcrumbs or non-emergency text messaging. I think SPOT (and the Iridium-based InReach devices -- which seem to have better coverage btw) make great satellite communicators for this purpose. I just don't think they're good emergency beacon replacements.

They were flying a Cessna 170B into a remote part of Alaska in August 1989 when they encountered an engine failure. They survived, and the plane was recovered shortly thereafter (performing an engine swap in the field no less!), but I think it illustrates pretty well the sorts of circumstances where you want something reliable for search and rescue teams to follow. (The video and its description are light on details regarding the type of device used.)
A handheld 406 plb like the ocean signal "rescueME" plb is essentially the same thing afaik.

(Edited to fix the date, which I typoed. I just watched this on an episode of Mayday, which did bit of a disservice to the NTSB and Embraer tests.)
At the time that video was recorded (1989), ELTs were analog-only... nowhere near as accurate, and very prone to false alarms.
The new 406 MHz digital beacons are much more accurate. :)
In this case, I'd assume they activated it manually since it wasn't a crash (nor was there an accident report on it that I could find)?
They were looking 5 miles away around a glacier!
I develop an app called Gaia GPS, which a vast array of backpackers, wildland firefighters, and SAR use as a tool to navigate in the woods. They use battery packs and rugged/insulating cases with their iPhone and Android devices to make them durable and long-lasting.
Even if you are a master orienteer who knows how to use a compass and a map with great skill, there are situations where you will be safer to have a GPS along too (either a smartphone or standalone unit). Situations like I have been in, where there is so much snow coming down, that you can't see the trail you're following or cutting, much less peaks or other landmarks.
In some situations, map skills and reckoning may get you home, but seeing yourself clearly marked on a map will make you safer too. People shouldn't fear GPS devices or phones as tools for survival and navigation.
p.s. This comment is FUD and based on anecdotes from two articles about Scotland.
I think you'll see the UI improved greatly this year... as of last Monday, we have 7 full-timers working on Gaia GPS, and we're looking for a designer to help with the UX right now. Things really blossomed in 2015, and 2016 will see more engineering work on Gaia GPS than any other year.
Fortunately, I really don't need much. Primarily recording (off)road trips in the Jeep, and downloading maps in advance of excursions where I suspect cellular data will be flaky.
Anyway, thanks again, and good luck!
"The root cause of getting lost is usually a lack of adequate navigation skills, no matter what technology is being used. In many cases, walkers do not have the skills to read a map or navigate effectively. Some mistakenly think that carrying a Smartphone or gps means that they do not need these skills, which is a recipe for disaster, for all the reasons given above."
From my perspective, it is about redundancy and flexibility within my environmental constraints. I usually just have my cell phone with me, even when I'm doing some potentially sketchy things. That's because if I break/lose battery/lose my phone, there are always tons more around me.
When that isn't true, I'll usually have at least a handheld ham with spare batteries, a list of repeaters around where I'll be, and GPS andd/or paper maps (along with other things of use when one is remote).
Oh, my phone, too, 'cause it is fun and handy. I just don't trust my life to consumer-grade tools built for the home and office that can't even get wet or survive a small drop.
If you are not familiar with outdoors adventuring (and even if you are), one important exercise is to think through your gear, asking yourself how you get by without each piece. What do you do if your tent poles break? Two flat tires or a blown engine? Something gets your food? Your phone (meaning comms and maps, for the purposes we're discussing) breaks or your spare battery shorts?
The initial maps download at home took a really long time, but I just put a phone on charger and allowed it to take time.
I love how it allows me to quickly create waypoints, so I marked my track manually every hour instead of using automated tracking. This helped a lot to conserve the battery life.
This is great for relatively small hikes. But if you're going off on a major expedition, then sure, you should probably take the professional radio and Garmin gear, and all the other survival gear people normally bring.
But if you've already got the lifeproof case and extra USB batteries, I think this Beartooth device looks pretty useful.
That's what I was about to post...like why am I paying for a WHOLE NEW DEVICE?
I have absolutely no affiliation with Beartooth, nor do I own one. But I have gone on long hiking and canoe trips in rural areas and could see a Beartooth as a nice addition.
The latter has 5 years shelf life, no subscription fees, communicates distress signal with GPS coordinates to a much larger array of low orbit Search and Resque satellites(so works better in canyons), if GPS fails to acquire position (again in a canyon) the satellites can also figure out an approximate position using Doppler effect and trickery with multiple receivers, has a homing beacon for S&R aircrafts, has a strobe light, is buyoant and water-sealed.
This is why unlicensed spectrum bands are great; they allow for stuff like this to be built without a billion dollar spectrum price tag.
That would assume lots of users which I feel can be problematic with a $399 price range and big form factor.
Solving a business pain vs a consumer nice-to-have.
I think maybe you're looking at the wrong use case. This doesn't replace GSM, it replaces walkie-talkies (or rather updates it for the text-based world). The use case is you and your friends are at an event downtown and cell service goes out (like it does when the sites are oversubscribed). You're camping and there's no service that far in the woods. You're in a disaster and trying to find your loved ones. It's short range communications, not long-distance calling.
Ham radio would go farther, but sending encrypted communications over ham radio is illegal, so that's right out. This is the next best thing.
A minor change of perspective and suddenly a 2 mile range is fantastic!
Encryption to obscure your communication is technically against the rules, but things like D-STAR need a proprietary decoder (the spec isn't open) to be decoded, so some people consider that encryption even though it's pretty popular and not being shut down: http://www.amateurradio.com/encryption-is-already-legal-its-...
The only part that's closed is the voice codec (AMBE). But if you just want to transmit or decode data packets, you can definitely build your own hardware. There's even a couple SDR modules for it:
http://www.flexradio.com/amateur-products/flex-6000-signatur...
http://www.rtl-sdr.com/listening-d-star-digital-voice-dsd-1-...
2 miles is amazing range. Bear in mind, these aren't
huge towers hundreds of feet above the ground with
50kWh power sources and million dollar price tags,
they're battery-powered, handheld, and consumer-priced
This guy did 7,600Km at 10mW on the 30m band, using a raspberry pi and a couple passives: https://gerolfziegenhain.wordpress.com/2013/04/13/raspi-as-w...Of course, the antenna was 44 feet long, and he was transmitting at 1.46 baud, using WSPR: https://en.wikipedia.org/wiki/WSPR_%28amateur_radio_software...
As Shannon proved in the 40s, you can get great range if you can sacrifice bandwidth: https://en.wikipedia.org/wiki/Noisy-channel_coding_theorem
How come? I don't know much about ham, but it doesn't seem like it'd make much sense to make it illegal.
Given the name, I would presume Bluetooth.
> Beartooth pairs with both iOS and Android smartphones, as long as the operating system is up to date.
Which is a pretty much useless statement on Android especially since they would know what API level their app targets...
It certainly sounds like it'll use Bluetooth though and makes sense as a bridge between the two devices. The only other real option would be Wifi or if you wanted to be weird for the sake of it you could probably do it through NFC.

Anyone know if they're encrypted? I'm not seeing any mention of that, I think I might grab a goTenna if only for that reason
No. Why is that sketchy?
It's probably because it's different from their competition and they don't want to release that signal yet. I don't remember GoTenna pre-releasing their exact frequencies either.
Android app is missing some great features like automatic group location updates. Right now you have to get location updates manually broadcast to you by each person in the group. Lots of crashes too.
I applied for an SDK but haven't heard anything back in three months. Feels like the project is dead, as there have been no android app updates in that time either.
Your hardware seems to be top notch!
Ahh, good explanation of the group updates functionality. Is this a problem for a small group of 4, every 15 minutes? Seems like not too much bandwidth if you aren't talking about an update ever minute.
forum about mesh networks, such as those products.
At a festival, cell service is fine. Camelback with gatorade/water mix is the crucial piece of equipment. Just keep an eye on it, as random people will try to drink from your straw.
For casual skiing we set times/places to meet up in case we get separated. Again, cell phones work fine on most mountains. Don't want to throw this bulky, expensive (not water/shock proof?) thing in a plastic bag in my pocket. If I'm going back country, go with a buddy. Keep an avalanche kit (shovel, beacon, air tube) in the backpack and bring a $30 pair of 6 mile, 2-way, replaceable battery, shock/waterproof radios.
Camping, the point is to get away from constant communication and leave the phone off, in the car. Again, bring the actual radios if you're going in deep.
Smartphones are great for day-to-day life and work, but I feel like half the point of the vacation is being able to untether.
I see a "Born in Bozeman" badges on the site, so I'm assuming this was born out of necessity for backcountry trekking in wild Montana and not hiking Mt. Tamalpais. I'm not far from Bozeman and I don't have to travel far from home before I lose network coverage from both Verizon and T-Mobile. Sure, I relish the loss of service in a way as a means of escape, but it has higher risks and causes a number of challenges that I think this seeks to overcome.
I'm intrigued.
http://www.outsidebozeman.com/places/wilderness-areas/absaro...
Most ski patrols use ABS to cushion the neck and buoy the skier above the snow, but this is supposed to be OK in a pinch if you can keep it in your mouth while tumbling down a mountain.
I have wanted that for some time as I think having radio tm for survival over some propriety thing beneficial for emergencies.
An example would be something like this https://www.cobra.com/products/professional/29-ltd-bt
But I want a smaller form factor to throw in a hiking pack and VHF support as well.
That being said I do own a marine vhf radio.
I wish they had more specs, less videos.
edit: ah, never mind (thanks linksbro)
Assuming 10 million a good number to kickstart this thing and make it useful in many locations, they'll need to make a few billion dollars sales in the next couple years.
Sometimes improved technology isn't the right solution.

> The range that a two-way radio advertises is the range that the radio should get in "ideal" conditions. Ideal conditions are line of sight, such as from a mountaintop to a valley below -- no interference at all.
> So what type of range can you expect from your radio? Usually half a mile up to two miles
https://www.fcc.gov/general/general-mobile-radio-service-gmr...
My gripe with the video's how it hides volume controls.
Many commercial two-way radios support both GMRS (up to 5 watts - $65 for 5-year license) and FRS (up to 500 milliwatts - no license req'd). Most users just ignore the GMRS functionality on their 2-ways.
http://www.amazon.com/gp/product/B001UE6MIO/ref=pd_lpo_sbs_d...
Agreed, they're great.
Walkie Talkie is consumer and no license.
The commercial FRS/GMRS ones requires a $90 annual license.
TL;DR unless you intend to get pretty into it and just want something for festivals and something to give to non-radio-geek friends to use, just get a FRS or GMRS radio. Motorola and Uniden both make quality sets that will work up to a few miles away at festivals.
Unfortunately all the unlicensed bands require band-specific hardware certification, which the Baofeng's don't qualify for, for various reasons.
Also, the Baofeng's aren't software-defined radios. Those cost much more money. :) It's just a standard programmable VHF/UHF radio, that happens to be very cheap.
Off the top of my head, any of these would work: Amateur radios that have D-STAR (connected to an Android phone), Garmin Rino, Motorola DTR, and TriSquare (discontinued, but you can find them on eBay).
I remember watching a video the other day of a guy talking about his gear for the AT and he went so far as to cut his toothbrush down and even talked about drilling holes in the remaining handle to further cut down on weight.
That said, something like this would be better than nothing.
On average you can expect a range of 2 miles
We have designed Beartooth to last for a whole 4-day camping trip, music festival, or skiing weekend with our typical messaging usage (3000 mAh battery)
Each user must have their own Beartooth device connected to their phone.
"Once you've paired Beartooth with your smartphone you can communicate with any other Beartooth users within range (about 2 miles). You can use Beartooth's app to talk, text, use maps, and share your location"
Which is unfortunate since one use case would be having a relay in car at trailhead to pass messages from internet.
At first glance, it looks like animation drawing functions are being triggered every frame regardless of whether or not anything needs to be animated.
However, if you get an Amateur Radio license, you can transmit in the 2 meter and 70cm bands at full power, legally, using your Baofeng radio.
