Tom, I've always used a gps handheld in conjunction with paper charts, using the electronics to give position by Lat/Long and finding where I am on the charts.

Will a handheld suffice? Would I need one that will download charts? How will I know where I am when I am far enough off shore such that no physical markings are visible on the gps screen? Does the gps give lat/long readings which I then need to look up on a chart? Any advice will be appreciated. Tom B, M17 #258
