Well if you want to be picky, you could say that a gps is any device that gives you longitude and latitude coordinates. A chart plotter uses those co ordinates and displays them on a easy to understand digital chart. For marine use these days, the term gps and chart plotter are used interchangeably.

You will also come across the term MFD or multi function display. These are the screens that you see and usually include chart plotting features. Look into garmin 400 500 and 700 series units if you're new to marine electronics. They are the easiest to use and have great customer service.

Thanks. Those are great links. I'm saving them. So a Chartplotter is a GPS that shows where you are with a map as the background. Kinda like the ones we use in our cars. Thats why I was having trouble understanding the difference. Your typical Tom Tom is actually a chartplotter for your car not just a GPS. Cool.

Exactly and if you drove your car off the end of the dock and into the bay then your Tom Tom would "almost" be a chart plotter.

I think you are confusing a GPS receiver versus a chart plotter. This is common since people refer to the receiver as a GPS. Technically, not correct.

GPS is a system (Global Positioning System) that comprises all of the satellites in orbit, the rockets it took to put some satellites in space, the transmitters within those satellites, the ground stations that are used to relay information to and from the satellite transmitters, etc, etc, etc.

A chart plotter may have a GPS receiver embedded within it. Or, it may get information from a remote receiver.

A GPS receiver does not have to have a chart plotter.

Yours is not a stupid question and blondeness does not enter into the equation. You have read so much mispeak for so long from so many others that the truth gets distorted.

Kind of like calling a throttle/shift control a "binnacle" or an anti-ventilation plate a "cavitation" plate.

Did you hear of the two blondes who were across a creek from each other? One hollered to the other "how do I get to the other side". Pause. The other blonde hollered back "you are already on the other side".

Thanks jethro1. I think I have the idea. Now the trouble is figuring which unit to buy.

I'm refitting the Sea Ray with all Lowrance. For me they do what i need them to do and are fairly easy to operate. You need to stop by a marine electronics store that has a bunch setup that you can play around with before making a decision.

I guess if I can't be fishing on a weekend like this I may as well play with the boat in my yard.
