Understanding The Convenient Features Of Marine Gps Fishfinders

The convenience of combination marine GPS fishfinders includes the ability to quickly

find those favorite holes which have been proven fishing spots in the past. Because you can lock in your coordinates, they can help you easily find your way back to proven fish producing areas, even if you are on unfamiliar waters. While a fishfinder GPS offers multiple advantages, fishermen have been using fish finder units for a number of years, while GPS units have been used to navigate unfamiliar waterways. Because marine GPS fishfinders serve a dual purpose, most fishing enthusiasts consider the cost advantages of a single unit, besides the waterproof portability offered by many units.

GPS technology works on satellite positioning to find the location of the GPS unit and your boat, while the fish finder operates on sonar technology to find the fish. When purchasing marine GPS fishfinders, you have a number of major manufacturers to consider and most of them are names that are already familiar to those that fish often. Garmin, Humminbird, Eagle and Lowrance have always been leading manufacturers of fish finding units and they are now the top choices of many that are searching for marine GPS fishfinders. While there aren't too many manufacturers in this field, there are some good products to select from.

With the variety of choices in marine GPS fishfinders, you can find vivid color displays, 3D readouts, GPS enhancements or just select those with the basic GPS operations. The same is true of the fish finder or depth finder portion of the unit because you can get a variety of enhancements for better viewing, and more information about the fishing conditions, including temperature readings and better structure or fish graphics. Of course, price can be a major factor, with fishfinder GPS units ranging from a few hundred to a couple thousand for the most elaborate models.

There are three main reasons that fishermen will tend to purchase marine GPS fishfinders which include the ability to save favorite hot spots, the ability to refer to navigation or topography maps and they help you easily get back to where you started from. You can easily mark your location when you start fishing to locate a home waypoint and once you find a spot that you are catching a lot of fish on, you can mark it and save it. In fact, you can mark hundreds and thousands of locations or waypoints, based on the model you select.

By saving your waypoints, you can get within ten to fifty feet of your favorite fishing spot and the GPS units that come with WAAS will get you the closest, because they are more accurate. You might want to look for units that are GPS-functional for the most convenience, because they have the GPS software and functions already set up in the unit. You may need to purchase an antenna or receiver, if you purchase GPS-ready units because they are capable of incorporating GPS functions, but you need to take extra steps to activate it. Regardless of what features you find the most valuable, the improvements in technology have allowed fish finders and GPS units to be available in a convenient combination unit that offers many advantages for avid fishermen, (or women)!
