On my last trip to Peru (2000), my digital camera was the most
"wowed" gadget, this time (2001), it's the GPS.
- Everyone will ask you, what is this?
- Adventure to places that were impossible to reach before
- Record your whole journey on to computer: good for revisiting or benefiting other travellers.
- Travel longer distant
- ...with shorter time
- Identify current location relative to other known way points
- Know where to get off when taking public bus
- Know the current speed, distant to target, ETA and many more...
What is this?
It's a eTrex GPS (Global Positioning System) that use the satellites
to calculate current location. It has a database for most of the
cities in the world. Even small towns like Selcuk, Bergama, Palmyra and Asyut
are included. It doesn't have a map. The higher model (eTrex Legend,
Vista) has mapping functions but is totally useless for the places I
went. To use this unit, you still need a compass, a map
and a good sense of logic.
How to find a location without a map?
First find a known location in your guide book (e.g. a bus station) and
mark it as a waypoint. Then figure out the relative direction and
distant of your target (from writing description of your guide book or locals), you can
then navigate to the unknown destination from the known position.
It is an entertaining mental challenge, but as soon as you
figure out one location, you can calculate the rest.
When it doesn't work?
1, inside buildings.
2, in deep vallleys
3, when climbing (with steep cliffs)
It works best in the desert where I marked the location of the camp and
could navigate from the village to the camp with an unknown path. It
doesn't work well when climbing. First the mountain will block most of
your signals. Then even if you can get a signal, your path is usually
going vertical and overlap with each other. If you follow the treks of your
GPS, you might end up flying off the cliff.
