Does using a GPS receiver make hiking safer?
That is a loaded question. The answer could be yes or no depending on the hiker. You must always be prepared for the difficulty level of the hike you have chosen. You can use the unit to keep you from getting lost by backtracking to the start. Having a GPS unit can help locate you in a time of emergency. Some of the less expensive units only show the direction you want to head in. They do not show the terrain between you and your goal. You should never place yourself in a dangerous situation by willful ignorance of your surroundings.
