In current times finding a fishing boat without some type of fishing device would be difficult. Fishing with GPS devices is the latest in water safety and technology are used for navigation and to mark a spot you plan on returning to. GPS stands for Global Positioning System and they are designed for navigational purposes. They operate using United States Government satellites that have been placed in orbit. Since they use satellites they can be used at any time of day and in any weather conditions. 

Every day the earth is circled by the satellites twice and the information from the signal is sent to the Earth. These signals can calculate the precise location of the user with triangulation and the precise pinpointing of exact locations. Triangulation means the latitude and longitude is calculated once the GPS receiver has been locked into three different spots. Once the location has been mapped by the satellites the GPS uses additional satellites to find useful information including the times of sunset and sunrise, destination distance, trip distance, tracking, and speed. 

Fishing with GPS is extremely acute due to the availability of the multi-channel designs. Once the GPS has locked onto a satellite, channels are used to maintain the lock. The accuracy of a GPS fish finder is up to fifteen meters with the accuracy increased with the newer models by up to three meters. Investing in a GPS has a lot of benefits and they are relied on more than traditional navigation like charts and maps. Once your plot points are saved to your GPS you can save frustration and time when on the open sea by going to the same location you found fish the last time you were there. Another GPS advantage is the ability to locate hot fishing spots older charts and maps cannot detect. You can even share your favorite fishing spot with a friend when you are on a different boat.

A GPS system is an important tool for safety when you are on the water. If you lose your concentration and get lost or turned around your GPS will lead you back home. Your GPS can be critical in bad weather like heavy rain or fog. A GPS system includes mapping software so finding a dock is easy. Your exact position can be communicated to a rescue crew or the Coast Guard if you have an emergency. 

A handheld GPS can be purchased at a boating store, a local marine, or online. A salesperson can explain the different costs and features for the various models. When you purchase a boat at a dealer your GPS needs to be built-in. You can easily obtain a reference for an individual to install your electronics properly. Do not rely on only one tool for navigation when you go fishing. Even though a GPS should cover you it is a computerized tool. Be proactive regarding your safety and always keep marine charts and maps on your boat. For emergencies, a handheld radio can be critical.
