The Garmin eTrex Summit is a simple, compact GPS device. View larger.

Behind the waterproof protection, you'll find the proven performance of a 12-parallel-channel GPS receiver, which will run for up to 16 hours on just two AA batteries. The antenna is internal, and the external power and data connector are protected as well. In addition to determining your location, the eTrex creates, names, and saves a location as an electronic waypoint in its memory--with room for up to 500 individual waypoints. This allows you to navigate back to a point any time you want, from any location--or, with Garmin's TracBack feature, you can reverse your track log and navigate your way back home. And once you start moving, the GPS provides other data, like speed, direction of movement, time and distance to destination, and more.

In addition to these basic features, the eTrex provides one more critical benefit: peace of mind. With GPS, you know where you are, where you've been, and where you are going. And since you always know your way back home, you can concentrate on enjoying yourself outdoors, on the water, or wherever your travels may take you.

Product Description
The eTrex Summit comes on the heels of the extremely popular eTrex, which was designed for both marine and recreation use. This new all-in-one navigation device for the outdoor enthusiast is the first combination GPS, altimeter, and electronic compass. The electronic compass provides bearing information when you're standing still and the altimeter determines precise altitude, so you can tell how high you've climbed and your rate of ascent.Like its predecessor, the eTrex Summit boasts a powerful 12 parallel channel GPS receiver and comes packaged in a small, sleek case with operating buttons located on either side of the unit. The case is completely waterproof to withstand immersion in one meter of water for up to 30 minutes.The eTrex Summit: it is what the hard-core outdoorsman has been waiting for.

It is great for recreation, has all the waypoint and track/route storage you will need. The "Geocaching" treks are great with this little gizmo. It is a great starter for the kids too! They are not intimidated by it and find it fun to play around with. I am so greatful that it is waterproof and for a second or three it floats!

I have been using it in my geophysical surveys to gage the general elevation change from a known surveyed-in well head elevation and have seen 1.5' accuracy relative to the survey point calibration. With a 1/2 to a mile-ling line this us very useful and you don't need to bring survey equipment with you. This is a great navigational tool! We input well locations and/or our planned survey lines and nav to them and end up where we wanted to be based upon an aerial photo review.

The odometer and speedometer are sure to surprise you in that they are very accurate considering most GPS units can track a vehicle, of any kind, up to 1,500mph to 1,800mph, ha, ha.

I do wish that the "Auto" calibration process would keep up with me after I have calibrated it once and have not moved more than three or five miles away from the cal point. It seems to loose it's cal quickly. This is a problem if you are not in a position to do a field cal on the fly, if you don't know the elevation or the altimeter.

I wish it had a WAAS upgrade! This would give me a 2-3 meter diameter of accuracy.

I may need to buy a WAAS gizmo and retire this one.
