Lowrance 250C GPS Question

engcon · #1 (**permalink**) 08-04-2007

I just bought my wife (a realtor) a Lowrance 250C GPS.
In looking at the Lowrance web site I see that the 250C can be used with the NauticPath Chart software.

I am wondering if this would be a good backup for the GPS already on our boat. We will be cruising the ICW, Offshore on Eastern Seaboard from VA to FL and to the BAHAMAS. I know that the 250C is an automotive device but with the NauticPath Charts would it be useful? With the street charts I know it would be useful when we arrive at a new port of call.

While not familiar with the unit in particular, I do know that many GPS units, like the Garmin 276C, are dual purpose units and can be used for both terrestrial and marine travel. If it can be used with nautical charts, it would probably be a good idea to have them. However, some nautical charts are better than others... so you should check the nauticpath charts for accuracy and errors.

NauticPath uses the same Transas chart database that Garmin BlueCharts and Nobeltec Passport charts are based on, but both of the latter have upgraded to private data for the Bahamas.

What this means is that these cheap charts are well worth it for the East Coast but BEWARE of using them for the Bahamas. The ONLY charts that are reliable for the Bahamas are the Explorer Charts. Buy them in paper and use your Lowrance to show ABOUT where you are but do NOT rely on it for exact positions OR depths as you would in the states. Plot your GPS readings on your Explorer charts and rely on their soundings.
