I recently ordered a SporTrak Pro from REI and expect delivery next week. I chose this receiver because:
1. It's waterproof, and I'm sometimes a spaz.
2. The receiver will function in an optional, windowed neoprene case, and sometimes I'm a spaz.
3. 99% of its use will be in the Sierra Nevada mountains and the state of Nevada, so its 23MB of available memory should provide more than enough space for uploaded maps.
4. I'll rarely use it while driving, so the 9MB basemap without a lot of road/highway detail should more than meet my needs.
5. Most reviews and comments I've read agree that the Magellan's antenna provides very good reception under canopy as compared to many competing units.
6. I didn't need a barometer or a barometric altimeter; the GPS altitude should more than satisfy my elevation curiosities.
7. It will work with all of Magellan's software products should I decide that I need more than just Mapsend Topo.
