Are you like off road adventures for example riding or driving your vehicle through unnamed, often unsurfaced roads and terrains or through mountains, snow, mud, rocks? Or you may be an adventurous hiker? In all of these cases, the best off road GPS makes the difference between a memorable off-roading experience or one that can compromise personal safety.
How a portable GPS unit works is it receives a signal from the satellites, fed GPS transmitted coordinates into A map and show the name of the street or the building corresponding to those particular coordinates. For personal GPS use, the GPS device uses google map to pinpoint the geographical location of the user. But during an off-road outing, the google map will not help you much since you are traveling in an area which name is yet to register on the Google map. Off-road navigation can be divided into three broad types. These are discovered type, waypoint navigation, and TrackPoint navigation.
This type is for people who are not sure where they are actually going. In this type, the off-road navigation system keeps tracking the path that one takes so if one gets lost, he can go back using the track data or one can also track the progress to avoid going back to the same place. But only a few excellent mapping software have these features.
This type allows the user to plan prior to his adventure. In this type of off-road navigation, the user inputs the latitude/longitude of the place that he wants to go and then navigator of the device will plot a route map for the user along the off-road terrain. Then the user decides himself whether he will take the most challenging or the easiest path to the destination.
Compare to the other two types; this type can either be the easiest or perilous. Trackpoint navigation involves somebody has already done the hard work for you by going through the track, record the track log and then give you the log that you can put into your off-road navigator to follow the same path. The danger lies if the track is forested areas, then flora and fauna might have changed over time and can prove to be a different tack altogether.
Besides these types of off road GPS, they can vary in terms of vehicles where they use for example car GPS, cycle GPS. Amid such variations, finding the right one is challenging.
