Whether on land or sailing the waves in today's word, a GPS device is necessity.

In today's world, you would be hard pressed to find a fishing boat without some sort of fish finding gadget. GPS (Global Positioning System) devices have become the latest in technology and water safety when it comes to fishing. They are used as a instrument of navigation and a way to mark your spot so that you can find it all over again in the future.

A GPS is made primarily for navigational purposes. They work off a network of satellites that are positioned into orbit by the United States Government. The best part about a GPS system is that because they function off satellite, they can be used in any weather conditions at anytime.

The satellites orbit the earth twice during the day and transmit signal information to Earth. The signals can then be used to determine the user's precise location by implementing triangulation and pinpointing exact spots. Triangulation means that the GPS receiver must be locked into three spots before a calculation of longitude and latitude can be displayed. After the satellites have mapped the locality, the GPS can narrow in on other satellites for helpful information such as speed, track, trip distance, destination distance and sunrise or sunset times.

The precision of the GPS system is very acute because of the multi-channel designs that are obtainable. A GPS will lock onto a satellite and hold that lock through one of their channels. A GPS fish finder is accurate up to fifteen meters while the newer models increase in exactness up to three meters.

There are countless benefits to investing in a GPS and individuals are using GPS more frequently and relying on them more than the more traditional ways of navigation such as maps and charts. If you have plot points that you have saved on a GPS, you may be able to save time and frustration on the open seas by going exactly to the location that had the fish the last time you went out. Another advantage to the GPS is that it can detect hot fishing spots that may not be detected by older maps or charts. In addition, if you find a |ideal fishing spot, you can share it with a friend when you go fishing on another boat.

GPS systems are also a fantastic safety tool when you are out on the water. GPS is an easy tool to use to find your way back home. You can also use a GPS system if there is unexpected bad weather such as fog or heavy rain. GPS systems are also equipped with mapping software that makes it easier to find a dock. The GPS is so accurate that it is able to communicate accurate positions to the Coast Guard or rescue crew if an emergency arises.
