One of my favorite things to do is hiking in mountains．Because
nobody likes the idea of getting lost，I always prepare before every
trip．But what’s the best navigation tool，a Global Positioning Sys-
tem(GPS)or a good old map and compass?
Five of my friends and I hiked through the mountains on a trail
(路線)I marked．One team of three carried a GPS，and the other
team used a map and compass．
It took the GPS team 3 hours and 1 1 minutes to get through the
whole hike，however，it took the map and compass team only 2
hours and 49 minutes．The biggest problem the GPS team met was
that they lost the satellite signal(衛(wèi)星信號(hào))in some places．With
no map or compass，they had to walk around until they were in a
place where the signal was good．The map and compass team was
able to spot different landmarks，compare them to their maps and then use the compass to point them in the right direction．
When I head out on my future hikes，I'm bringing a map，a compass and a GPS to show me the way．
