===Optimizing GPS Displays===
In the Setup menu under Page Sequence you can select displays that are useful for you i.e. the Map page, the Compass page, the Elevation Plot and many more. By hitting the back button you switch between your pre-select pages without selecting them every time in Main Menu.

My pre-selected pages are:
*Map: Shows the current location on the maps and permits zooming and panning to plan ahead. This is my most frequently used page.*Compass: You can select on the map a point an aim for this point using the Compass page. This is useful in cross country terrain and when packrafting in open water. If your device does not have a magnetic sensor (i.e. the eTrex20x comes without compass) then the orientation is only shown correctly while moving.*Elevation Plot: The elevation plot does not shrink mountains but shows you at least what you climbed and descended. *Trip Computer: You can select the values that you wish to get shown on this page. We tend to reset the counter daily to monitor our daily advance but you can keep the counter running if you love to see big numbers.*Sun and Moon: Knowing sunrise, sunset and moon status is useful to anticipate natural light and know your death-line for finding a suitable camp site. Also the calendar is handy when approaching a section end and planning your resupply trip.*Satellite: In dense forest satellite signal reception may be compromised. This page helps to understand the accuracy of the displayed location.
Several hikers who attempted to hike parts of the GPT had to abort and backtrack because they were unable to manage the track display, did not set up topographic maps correctly or run out of power on the trail. A proper learning and testing period before the adventure on the GPT could have prevented this.
 
So, reading GPS suggestions does not replace personal practice with your GPS device. A proper hike would be ideal but even testing in urban areas will be very helpful if you use your GPS with a playful attitude and test the different features and options. Be curious and not scared to change settings. Play! Have a stroll around your home with your GPS, record this track, download the GPX file from your device, convert it into a KMZ file and review your stroll on Google Earth!
 
Therefore, if you do not have a GPS yet, purchase one latest 3 month before you depart and practice. Setup your device yourself and don’t ask a nerdy friend to do it for you. Only if you learn to do it yourself, you will be able to understand and solve your GPS problems yourself when you have nobody around to ask.
 
===Practical Considerations===
The GPS device should be carried high up on the body within easy reach to facilitate frequent location checks. A mostly unrestricted view to the sky improves the GPS accuracy and minimizes the power consumption. Therefore it is not advisable to carry the GPS i.e. in a hip belt pocket.
