this be my second gp -lrb- I upgrade from a eTrex Legend -rrb- and I love it ! it do a excellent job keep a signal when in the wood where my old one would not have have a signal at all . I also like the digital compass and altimeter even though I think they would just be another toy feature when I buy it . I have some map load on it now too and with a 1gb card I can hold most all of the US . you can also save the track to the memory card . the navigation feature do not seem to work well for I though but I think that may be because I be use a old version of Mapsource -lrb- v7 -rrb- . overall I would highly recommend this .
