Designed specially for outdoor excursions, the Garmin eTrex GPS receiver helps you to identify your position precisely. Using the WAAS technology, this Garmin GPS receiver pinpoints your location even when you are next to a tall building or in dense foliage. As this handheld GPS is water-resistant, you need not worry even if water is splashed on it accidentally. With a single charge, the Garmin eTrex GPS receiver gives you a battery life of up to 17 hours. The TrackBack feature of this Garmin GPS receiver allows you to navigate back to the starting point. The five buttons located on either side of this handheld GPS facilitate a user-friendly operation.
