When looking to get a handheld GPS, you want to make sure that it will be rugged and hold up to the terrain you are set to take it. The first thing to consider is where you will be going and decide on investing in a GPS that will hold up to that terrain and weather conditions. Having the ability to have a waterproof GPS is always a great feature, just in case you get caught in some nasty weather. Most of the GPS's on our list are water-resistant, but the best way to ensure is to do the research and also check the customer reviews.
