Is your chartplotter up to date?

If you are like us, your chartplotter was not purchased this year.  Or last year.  Or the year before that.

That probably means that not only are the charts out of date, but the software that runs the chartplotter is obsolete too.  What’s a boater to do?

Certainly one option is to go out and buy a new chartplotter.  But that expense may not be necessary.

Our chartplotter is a Garmin 520 – very old indeed.  And when I hooked up an AIS receiver to it, I began to get an inkling that something was not quite right.  The main shortcoming that started this whole thing was that only Class B AIS targets were being displayed.  At first I faulted the AIS receiver, but no, it was actually the fault of the chartplotter.
