B. Gray, The Vista is a great unit that I would probably recommend to someone looking for a gps for both hunting and fishing, the 24 meg download is by far the most of any handheld and the electronic compass and barometric altimeters are pretty cool, the downside though is the smaller screen, no tide table/celestial chart (can be downloaded) does not float and the buttons are not as easy to use as the 76's. If your looking for just marine use the 76 has better features.
