Some possibilities offered by this device, almost all do the same, although some differences explained below. And these fundamental differences are based on the presence or absence of altimeterThis makes them to give us very accurate data related to those that have height, and the presence or absence of electronic compass, Which makes those who have also stopped functioning, ie they are able to tell the direction or measuring distance or the cardinal point where we stand. Those who have no compass only work to pursue a course when we are walking. Not to say neither one nor the other do not give us the altitude at all times (but with less accuracy) and the cardinal points (but not stopped). Those are the biggest differences, of course, accuse the price and when walking more comfortable but not fundamental.
The GPS software have several screens. One, to tell us where we should go to pursue a course or to reach a specific place or to follow a path that we have made previously on the computer, as I will explain later. Another, with the compass, which, by means of an arrow also indicates the direction to follow, and the cardinal points and other data. Others give us interesting data, which can be quite varied. Depending on the GPS this data can be: speed we carry, we kilometers traveled, distance left to us to reach a particular point, the time it will take to arrive depending on the speed that we, as long as we are moving, the While we stand, the average moving speed or the total average speed height at a specified time, the cumulative rise in whole tour, accurate meters will have at all times the device (ie, the maximum error we can commit, even going by where we indicated, does not usually exceed 10 usually meters), height profiles and much more data and unhelpful. There is a display devoted solely to this type of data and another with the main menu to access where we want. Can there be any more appropriate. You can customize many details.
