Tracks are another useful Magnetic GPS feature

A waypoint is simply another name for a position or specific place. When you reach the trailhead of your next hike and you select the “mark” button on your Personal GPS Tracking Device , you are, in fact, saving your current position as a waypoint. When you manually input the position of the geocache you are trying to find, its position is a waypoint. Depending on the robustness of your GPS receiver’s memory, it can hold hundreds to thousands of waypoints in its library. Then, navigating to a waypoint is as easy as selecting one from the list stored on your receiver and entering “go to.” Navigating in this fashion, from a place to a singular waypoint, is often not practical due to terrain, buildings, or other obstacles. Therefore, we find that navigating via GPS receivers is done by following a string of waypoints, known as a route. Just as you wouldn’t drive from your house to the grocery store in a straight line, you won’t hike, paddle, or bike from the trailhead to a campsite in a straight line either. Instead, you’ll want to go from one point to a place where a major change in direction is encountered and so on until you reach your destination.
To do this, you’ll first need to create a set of waypoints at each of these “intersections.” In the grocery store example think of this as waypoints for your house, for the intersection at the end of your street, for the next street you turn on, for the road to the grocery store, and then the parking lot of the shop. The same principle applies in the outdoors, with waypoints commonly being created at trailheads, trail junctions, or other key landmarks as a means of making sure you are on the right path. Creating a route in your Waterproof GPS Tracker is as simple as selecting a set of waypoints in the sequence you want to travel to them. Once again, routes vary by receiver; some units are able to hold a few, while others can hold dozens. Routes are generally able to contain twenty or so waypoints, but again, this varies. When following a route, your GPS will point you in the direction of travel to the first waypoint on the list, and when you reach that waypoint it will automatically go to the second, and so on.
Some receivers also give you the option to reverse a route, taking you back the exact way you came. For geocache hunts that require navigating through large parks or take you on long hikes, routes are a great way to quickly and accurately navigate. Tracks are another useful GPS feature. Most GSM GPS Tracker create a “track log,” a figurative breadcrumb trail of your positions. The track features on a GPS receiver can be programmed to record your position at set intervals, perhaps every minute or every ten minutes. Tracks create digital records of how you got to where you are, and in the worst case scenario they can lead you back to where you started. Beyond the safety net that a track log creates, it can be used as a great mapping tool for those with some of the topographic mapping software.
