Let me address the elephant in this room. The fish finder is equipped with GPS and mapping, but not with a MicroSD slot. This means you are stuck with the unit that came with it and can't purchase or download any additional Garmin mapping.
Genesis Live mapping ranks among the top in the field. C-Map contours in high-resolution detail are provided. You can also find one-foot contours at more than 5,000 lakes. If you fish up North, there are also 9,400 Canadian lakes. To access these information, you'll need the SD card.
Worldwide Basemap is Garmin's standard offering. It is the same technology used by their land GPS. Access to ocean maps, rivers maps, and streams up to 100 feet long will be available. Access to land data such as airports, urban areas and territorial boundaries is also available.
What exactly is a GPS-fishfinder combo? GPS fishfinder combo is an electronic device which combines both a GPS and fishfinder into one compact device. The size ranges from 7" to 16. They have an LCD screen with color and built-in GPS antennas. Some fishfinders also feature internal sonar such as side imaging and CHIRP. Some models can also be linked together. Lowrance, Simrad, Garmin, and Garmin are all popular brands.
Before I begin, I have to mention that so many of the premium features in this fishfinder are premium upgrades. The barebones models have nothing but a standard fish finder. If you don’t plan to upgrade, you’d be better off getting a lower model.
FishReveal technology, one of the most important features of Hook Reveal, is one of its best features. The FishReveal technology allows you to view both fish arches as well as structures simultaneously. This feature is becoming more standard in many fish finders, but it still impresses.
The GPS feature offers 2,500 waypoints, 45 routes and integration with AutoChart or Live Navionics. These are premium upgrades and will almost always cost more.
