Question

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 System（GPS） or a good old map and compass？

Five of my friends and I hiked through the mountains on a trail（路线） I marked． One team of three carried a GPS， and the other team used a map and compass．

It took the GPS team 3hours and 11minutes to get through the whole hike， however， it took the map and compass team only 2hours and 49minutes． The biggest problem the GPS team met was that they lost the satellite signal（卫星信号） 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 （认出）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
