| As with any smartphone product being marketed for use in wilderness environments, a note of caution is necessary. 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. https://www.thebmc.co.uk/smartphone-apps-handle-with-care http://www.bbc.co.uk/news/uk-scotland-highlands-islands-3380... |
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.
