Many GPS units automatically maintain tracks (Garmin eTrax for example) when it is on so you can back track if you get lost. Very useful when hiking in the bush.
Way points usually refer to positions you mark manually and can be connected in routes for planning purpose. The difference is that you have no access to what "internal" way-points are used to maintain tracks on the GPS itself. Usually you need a PC and a mapping program to pull off the tracks and turn them into way points and routes. As for batteries, I would recommend carrying a spare set or, even better, use the GPS with a compass so you don't need to have the GPS on all the time :-) /sc On Thu, 2002-03-28 at 09:51, Greg Franks wrote: > Some GPS units allow you to store way-points (effectively "virtual" > crumbs that you "drop" marking your route).
