There are some key things to do to keep safe in remote areas such as :
- remember that the GPS unit needs to “see” the sky to get an accurate fix: it may not work well in canyons or under heavy tree cover.
- carry spare batteries for your GPS: most portable GPS units should have about a 24 hour battery life but carry a spare set of batteries and battery charger;
- test that you are where you thing you are by using the GPS in town or near the area you are heading to. Use a waypoint such as major road interection or other local landmark to make sure your unit agrees with the co-ordinates you are using;
- bring your manual with you in case you need to figure out something!
- always carry backup maps and a mechanical compass;
- be aware of the general direction that you are traveling in: hint sun sets in the west;
- make sure you have the GPS unit set to the correct coordinate system: your maps or guidebook with way points will tell you which one to use;
- if you are walking – make sure you record where you left your vehicle: write this down in case something unexpected happens to the unit: at least you will be able to find your way back using a map or someone else’s portable GPS;
- if you are using the unit to record your route while you walk and intend to retrace your track: again practice in a town or other safe environment to ensure that you know how to use the unit!
