Know Your Fishing Location With Combined Fish Finder And GPS

The most revolutionary change that fish finders have undergone has been of the amalgamation of the Global Positioning Systems within the sporting unit in the boat models and the portable units. One of the first aspects that you will think of while shopping for a fish finder is likely to be the GPS since it is such a useful tool.

A GPS fish finder helps in navigation and recording fishing locations with precise accuracy. You naturally do not want to lose your way in the open seas. Moreover, many times you are reminded of a location where you found a lot of fish. You want to find your way back to the fishing spot but are unable to due to the absence of a convenient tool to guide you. Maps and compasses do help but if you have kept a note of the location you can go back to the exact same spot and repeat your fantastic fish finding performance. Many fish finder models that are equipped with a GPS facility can help you in both these situations.

The Global Positioning System is a network of 24 satellites that the U.S government has placed into orbit. It is a navigation system that works in all weather conditions and is totally free for use without any set up charges or subscription. GPS satellites transmit signals to earth while circling the planet in their precise orbits. These signals are then used to calculate the exact location of the user by the use of the trigonometric method of triangulation. When a GPS receiver is locked on to the signals of at least three satellites, it calculates the longitude and latitude and thus tracks movement.

Most fish finder systems come with entry level GPS, for those who do not want to spend much. There are also available more sophisticated state of the art systems for the hardcore fisherman.

Fish finders with super accurate GPS chart plotting will ensure an unforgettable fishing experience and provide you with confidence that you are sure to return home safely. GPS enabled fish finders are capable of directing you back home, no matter how far out to sea you travel. The new 12-channel GPS receivers are accurate to the nearest fifteen meters whereas those with Wide Area Augmentation System (WAAS) can get you to a spot as close as three meters from the exact location.

GPS receivers that are installed in fish finders use the most precise method of electronic navigation available to anglers. They are sturdy, accurate, and easy to read but at the same time it should not be forgotten that they are only tools. Keeping an alternative method of navigation handy while out in the open seas, like charts and compass will prove helpful in case of any unforeseen circumstances or emergency.

One popular make you can research is Hummingbird fish finders, they have a wide range of models that suits any pocket and meets the requirements of most fishing plans. Hummingbird fish finders with GPS are composite units with a sonar fish finder and a GPS chart-plotter with a built in or external antenna. On a marine chart-plotter your position is superimposed over a moving map to enable you to see your position all the time. The ones that come with a track-plotter will let you save your position to access later on.
