handheld gps units

I use my unit to log traces of my hikes and runs; so good, continuous reception is my most important criterion for judging this unit.

I originally bought a Garmin eTrek GPS unit, but I had to return it. Reception was fine when properly oriented, but the small size and antenna design caused it to lose the satellite signal even under clear skies while I carried it in my hand. I could get good reception only if the unit was held horizontally. This makes it worthless for logging runs and hikes.

The user interface on this Magellan is OK: it's easy to use on the run and somewhat customizable. It's also not too hard to learn to use. But some simple data isn't displayed, like time elapsed since start of trip, or average pace (though average speed is available.)

Map quality is good, and the CD to download detailed maps is included, unlike the Garmin. Also, topographical data of most of the US is preloaded. But this I've been disappointed with, since it seems far less accurate than the USGS maps available in electronic form from National Geographic. Often, a steep uphill appears on the Garmin map as a downhill, while the data loaded into the USGS maps shows the altitude change correctly.

But again, this is all secondary to the good quality reception of the unit in different orientations. Since this is good, it gives good traces of my runs and hikes, and so I'm happy with it.
