I can therefore assume that you won't be sailing with the US Navy, the British RN or other major Navies/Shipping lines anytime soon. Your boat your choice, not my problem.
Robes, The GPSMAP® 78 Handheld GPS is a good unit and the price is right. The reason that the write ups are similar between models is that they all do the same thing, they calculate your position from a series of satellites and display it in various formats. If you can actually plot the Lat/Long from a Gps onto a chart that would put you in the top 5% of boaters.
