...of guesswork and estimation in this and in poor conditions, updating the chart can be difficult and especially so if the crew is inexperienced at boat handling. Magellan GPS 2000 - a solution? Yes – one of them. Never a substitute for accurate chartwork, DR navigation and log-keeping. There are other ways of finding out position like Decca (Europe) and Loran (in the US), but both these methods, based on radio beacons have built-in errors and still require some adjustment. Satellite navigators like GPS 2000 used to have built-in errors for US defence considerations, but in August 2000 these were removed and the accuracy of readings improved from around 10-100metres down to what is now about 1-3 metres from my observations.

...I wanted a small GPS unit principally for my off road mountain biking activities. It's a real hassle stopping the bike unfolding the OS map and working out precisely where you are, on a legitimate bridle path or in a farmers backyard.

At first I used to print out the directions from mapquest or theaa.com and then try to follow these, but always I used to lose or miss out in between and land up searching again.
