What GPS to buy?
I recently bought a Garmin 76S. It''s a handheld unit that is water resistant, floats (for a while), and holds 25MB of memory. It is WAAS capable and accepts the Garmin Bluewater Chart software. (BTW, I''ve downloaded the entire Chesapeake data into the unit and still have 5MB to spare.)
Also, it has a built in barometer, compass, and tide info for many selectable waypoints. Since I have Garmin Road and Topo software, the 76S was the optimum selection (for me). The fact that I got it new on ebay for about $350 made the decision even easier. ;^)
