The casual adventurer needs the Garmin eTrex 10 to show directions when wandering through the forest or the streets. This handheld GPS is armed with a sunlight-readable monochrome display and a worldwide basemap making it easier than ever to know where you are and where you are headed next. Although the eTrex 10 doesn't have all the bells and whistles you get with other, more expensive, handheld GPS units, if you are searching for a basic GPS unit to use for your casual outdoor activities, this is your unit! It's affordable and friendly. If you believe the world is your oyster, Etrex 10 offers possible geocache bonuses when you trailblaze. Experience more fun with Garmin geocaching. Geocaching is a high-tech version of hide-and-seek where you explore the outdoors in search of hidden "treasure" and adventure. Geocaching is a real-world, outdoor treasure hunting game using GPS-enabled devices. Participants (members) navigate to a specific set of GPS coordinates and then attempt to find the geocache (container) hidden at that location. A perfect way to get started geocaching is with a compatible Garmin GPS (like the Etrex 10) and geocache coordinates. The eTrex 10 is lightweight and compact, and with the high-sensitive receiver, you won't have any trouble getting a satellite signal even in deep canyons or under heavy tree cover. Use the optional bicycle mount for all terrain bike riding and let the Etrex 10 guide your way. Over the rocks and into the water, your eTrex 10 is waterproof to IPX-7 standards, meaning it can be submerged for up to 30 minutes at a depth of 3 feet. Finding your way through unexplored areas and back is no small task for the casual adventurer. The convenient, handheld Etrex-10 GPS is the necessary tool to tackle new areas without the fear of getting lost. With geocaching membership, you can engage in amusing outdoor fun and games.
