Though I haven't yet seen much improvement in location performance in this unit over my Maggie, it has some bells and whistles I like.
- The biggest improvement is the USB connection. Comm port is a real pain and sloooooow.
- The increased number of caches it will hold is also very nice and one of the reasons I bought it (though I thought it held more without using the card).
- I really like the direct download of a cache's coordinates.
- The easier battery change-out is another plus.
- It doesn't let GSAK erase/flush the existing waypoint load/set when refreshing it -- I have to do that
- It doesn't start coordinate averaging automatically when I stop moving.
That's about it for the way I use a GPSr. Was all that worth $350? I'm not sure.
If I think of other advantages I'll come back and list them.
