For the adventurer / WAAS enabled GPS receiver, eTrexH locates your position quickly and precisely and maintains its GPS-location even in heavy cover


Perfect for outdoor enthusiasts on a budget, eTrex H comes with a high-sensitivity GPS Receiver that locks onto satellite signals quickly and maintains accuracy — even in the toughest conditions. And just like the popular eTrex, this little yellow wonder combines an intuitive Interface and a rugged exterior into a lightweight handheld that fits in the palm of your hand. With eTrex H, your adventure can last and last — up to 17 hours on just 2 AA batteries. While you roam, you can store up to 500 waypoints in Memory for easy retrieval. Just enter the point you want to go to, and eTrex H points you to your destination (no street or terrain maps). To get home, use Garmin's exclusive TrackBack feature to reverse your track log and help you navigate back to your starting point.
