In the mountains, equipment and security surely go hand in hand.
It is clear that safety in the mountains depends above all on common sense and on the ability to recognize one's own limits, but it is equally true that adequate equipment allows us to move and operate at best with inadequate equipment.
I was born and I've always lived in the mountains, for thirty years I've been a mountain guide, and I've seen a lot of people going through the mountains: well, unfortunately I still meet people who face the mountains without the right equipment, or even worse with old and unsafe equipment.
equipment-rucksack On the via ferrata, for example, you often meet the "expert" hiker who gives advice as a grandmaster, and who maybe even moves well enough on the rock, but wears a harness that could be exposed in a mountain museum, with 8 mm cord. old and carabiners no longer on the market for decades.
And, if you kindly and obviously only for a good purpose make him notice it, he often replies: "It's true, but I'm so fond of my mountaineering material ... And then I do not fall!" ...
Unfortunately, the fall is potentially subjected to anyone moving on vertical terrain, be it a beginner or an experienced mountaineer; it may be because of a stone that strikes us, a thunderbolt, an inattention. The equipment of those who go to the mountains must be complete and of excellent quality.
The Altimeter GPS app uses the integrated barometer of your iPhone (available from iPhone 6S or higher). It shows useful indications such as atmospheric pressure and weather forecast based on the barometer.
The data displayed are the result of the sensors in the mobile device, ie the GPS and the barometer. If the latter is not available in the terminal, the data will be less accurate as the app will be based on data from local weather stations, if available.
On Garmin GPS it is possible to activate tracks as routes simply indicating them as a destination for the "where to go" function. Normally the tracks will be navigated in the direction in which they were recorded, having to reverse the direction, you can act directly on the track from the management menu "track manager" and then activate them as a route.
