Common GPS Features on Fishfinders

ContoursGlobal Positioning Systems have become a staple in the lives of people all over the world. From finding directions to new amusement parks to purchasing these devices as gifts for people on special occasions, a GPS is often essential in a wide variety of situations. Though most people may not know how far reaching these systems have transformed certain industries, they may be surprised to find out what they are being used for. One of which is using a global positioning system for finding the best fishing spots. In fact, fishing enthusiasts all over the world are incorporating these devices into their fishing ventures, specifically as a means to enhance their fishing experiences.  Now GPS units can use 3D maps to provide the most accurate information available.  Therefore, when a fisherman is getting ready for one of their fishing trips, they should make sure that they are taking a fishfinder GPS along with them.

A fishfinder GPS is an idea for finding favorite fishing spots all over the country and even abroad. There is a bit of a learning curve when using a GPS, since there are tons of new features that come with a GPS fishfinder. However, as the fisherman becomes more familiar with the features in these electronic devices, they usually become well versed in finding the features that they are looking for. In order to gain the knowledge required, however, each individual will have to do their own homework.


Tracking Features and Accurate Readings


Once the initial difficulty of learning how fishfinders/sonar works along with the GPS system, the user will begin to get an accurate reading of the things that they are trying to track or measure. For instance, the features on a fishfinder will allow the user to mark a variety of different things including underwater structures, creek channels, river patterns, contour breaks, and numerous spots where the fisherman has had great fishing results. In fact, by using specific features on their devices, they can return to the exact same spot whenever they want to go. This information is displayed via an LCD screen.  A great example is the Lowrance structure scan, which overlays past sonar images onto the map providing great detail and information for fishermen.


If the fisherman wants to know a little more background of where they are and what’s going on, they may use the features on fishfinders to provide them with numerous types of information including their current latitudes, longitudes, altitude, and surface speed. Based on the information that they are trying to secure, the fisherman may also view information about the sunrise and the sunset.

In addition to the GPS that is included on a fish finder, Map packs can be bought which give great detail about specific bodies of water.  There are chips that give detail in 1 foot contours on lakes that have been scanned and mapped by the GPS company.  These really provide and edge, for example we use ours fishing out of South Haven for salmon.  Trying to pick out a spot 10 miles off shore where a bait pod will be is made alot easier when you have the contour information at your finger tips.  Alot of times that can be the difference between success and failure.



Since fishfinder’s technology is based on information that is supplied by satellites, its accuracy is not affected by challenging weather. For instance, the user can still obtain accurate information in the fog, dark and even in bad weather. In fact, in emergency situations, the user can also tell people who need the information exactly where they are so that they can receive the help that they need.

By using specific features on a fishfinder, the user can also log the coordinates where the best fish may be found. Thereby, allowing fisherman to study the actual topography of a specific place, especially where they find the fish trolling. For instance, the fisherman can use the track logging feature so that they can go back on their next fishing expedition.
