gps signal

[spanishmak]

What's up everyone.I have a nuvi gps that I bought for my boat and I was wondering if I could use this on my boat up to maybe 15 miles offshore,would I get a signal or not cause marine gps has external antenna I do use it for hunting in the offroad and pedestrian mode and it works fine.Can anyone help

In one word....ABSOLUTELY. The signal to your GPS comes from satellites hovering around the earth up in space.

The last couple of gps I have had all have had internal antenna's, and they have always worked.

My Garmin Marine unit has internal antenna and as Cam said since it's based on satellites, it should technically work anywhere on earth that it can see the satellites. I believe it needs 3 to pinpoint your location.

Not familiar with the nuvi, but i would think the main limitation between this and a marine unit is the maps they have. So basically the amount of info you will have about the waters such as markers, channels, depth...

Now that you say that I wonder if I can download the maps onto this unit

I have one and they show nothing but land and roads, you will see nothing but a big blue area for water.
