[pct-l] GPS, Walkie-talkie


I agree, a GPS is not needed on the PCT. It's much more useful on the CDT 
where you'll find yourself lost a lot more. Yes, lots of people have done 
just fine without one. But consider the following situations that I 
encountered in '01:

1. You're in a somewhat featureless desert area and you have GPS coordinates 
for a spring.  The GPS can get you right there with no guesswork. Without 
it, you would have to navigate with precision on a map where one inch is 
almost two miles.

2. You come to an unmarked trail junction. It may be the one marked on your 
map, or it may be one of the many animal trails that cause constant 
confusion. You haven't been paying too close attention to your location in 
the last couple hours and there are no clear landmarks in the vicinity. 
Which way do you go? Get out your GPS and see if you're at the marked 

3. You're going cross-country up a canyon and need to take one particular 
creek up to a ridge. There are several creeks coming off that ridge. How do 
you know you're at the correct one? Your GPS will put you on the map.

4. You're going cross-country in the snow.  You've gone from ridge to ridge 
in forest for so long you can't be sure where you are anymore. Your GPS can 
put you on the map.

5. You've been going cross-country and you come across a road. It might be 
windy road A, in which case you want to follow it to the left. It might be 
windy road B, in which case you want to follow it to the right. It might 
even be an unmarked logging road in which case you don't want to follow it 
anywhere. Your GPS can tell you which road it is.

6. This didn't happen to me, but you mention interest in carrying a radio or 
phone. Presumably one of the reasons is to call for help if you should 
become injured and immobile. How do you tell the rescuers where you are? GPS 
coordinates would be useful.

You get the idea. Without the GPS, you'd just guess. With the GPS you guess 

But a GPS is not a substitute for map and compass skills. Once you know 
where you are on the map, you still have to navigate to where you want to 
be. A GPS with a built in map would help, but you'd use up a lot of 
batteries on a thru-hike using that map. And what would you do if the GPS 
broke during the hike like mine did, or the batteries die? Is the built in 
map useful enough to plan an alternate route or does it just show you your 
immediate vicinity?

I recommend using a GPS on the CDT. But the only thing I use it for is to 
tell me my current coordinates which I then plot on my map using a GPS 
waypointer. Any GPS will do that, so buy the cheapest lightest one you can 
find. I like the yellow Garmin Etrex. I bought mine on Ebay for about $100. 
It weighs 5.2 ounce with standard batteries. It's a bit lighter with Lithium
