re : GPS
Joe,I have a GPS76 which does not have the mapping capability. The GPS76 MAP includes base maps of the world including aids to navigation. What it doesn't have is detail charts. It doesn't show water depth. For my part, I carry paper charts of the areas that I'm sailing in, and reference them for the depth information. The small screen on the 76 makes it a little difficult for 55 year old eyes (at least mine) to see the detail anyway. Your best source for Blue Charts is the Garmin website, or any retail outlet that sells Garmin. The Blue Chart prices don't tend to fluctuate much between different retailers. You can pick up the Mapsource Blue Charts US Recreational Lakes for $116.00 from Garmin. http://www.garmin.com/cartography/mapSource/reclakesEast.jsp#
