Yes, Audio GPS is available for Marine use. It can also be use for car GPS. It comes with features such as video, speech of street location and/or destination, and speech of left and right turns.
You should be able to use a marine GPS chartplotter anywhere. The whole point of GPS devices is to help navigate and plot where you are.
Depending on the brand and model, the number of points one can plot on a GPS varies. For marine use, a chartplotter GPS with a fishfinder is recommended.
A good use for a marine GPS Plotter would be if you took it fishing with you on your boat. It will help you keep track of your location and will ensure that you won't get lost.
These devices are mainly used in boats. These devices use GPS to track you on the body of water you are currently in in your boat. They work similar to GPS systems used in cars.
The Humminbird GPS receivers I can find info on are designed for marine and fishing use - such as when sailing on the water in a boat, yacht, ship, etc.
Yes, marine navigation systems also use satellites for mapping. In fact, all GPS systems use a network of orbiting satellites to calculate the precise location of the GPS unit, whether it's on the land or in the sea.
I would think that a magellan marine gps would be water proof since you would use it on the water. Your best bet to find out if it is for sure water proof is at this website http://www.magellangps.com/Navionics-Marine-Maps.
In 1983, the GPS ceased being solely a military system and was made available for public use.
A marine GPS is another word for a fish finder. They normally tend to use sonar. You can buy one from http://www.gpscentral.ca/products-marine.html. There are other alternative places but this one has just about all of them.
GPS devices can complement marine charts but are not a complete substitute for them. While GPS provides real-time positioning and navigation, marine charts offer crucial information about water depths, hazards, and navigation aids that GPS alone cannot convey. Relying solely on GPS may lead to navigation errors, especially in areas with poor satellite signals or when electronic failures occur. Therefore, it's essential to use both tools together for safe marine navigation.
You could, of course, use your phone as your in car GPS system. There are plenty of items available that allow you to attach your phone to your dashboard.
