- Still, without a topo map, how to you know where you are?
- If your little GPS box says you're at
- 118 degrees 47 minutes N, and 36 degrees 54 minutes W
- and at 4155 feet. Do you know much without a topo map?

- Back to the Subject, a few months ago I baught one of the
- new casio altimeter watches. It is most useful when I
- remember to set it at the start of a hike. Then using
- a topo map, I can more easily find how far along the trail
- I've gone (assuming there is some change in altitude).
- The drawback is I'm alway pullng out the map now and
- checking my position. Hopefully the novelty will wear off.
-
- I also like the "sample every 15 minutes" function.
- It can hold up to 50 samples. So if I set it at the start
- of the hike, at the end I can go back and look at the hike
- in profile on the bar graph display.
-
- The accurray it's the greatest ... 20 ft increments.
- And on a typical day hike loop, it is usually 100 ft off
- from the start to the finish.
