The eTrex 10 GPS from Garmin is the ideal unit for the first time users. It has a simple, fuss-free design that is rugged and easy to use. It can be operated with just one hand thanks to the well positioned buttons and has a clear, easy to read screen. It\'s bright yellow colour makes it easy to find at the bottom of your pack or in low light conditions and it has a water rating of IPX7 so it can take an accidental dunk in a puddle without coming to much harm.It is ideal for paperless geocaching, supporting GPX files so you can get the details straight to your unit. By going paperless you help the environment because you aren\'t using any paper but also it allows more freedom and fun with the geocaching activity itself because you don\'t have to spend time manually entering coordinates or handling paper print outs.
