You can also design your own maps. Once you have created travel routes, you can use that information to help you plan each trip to a particular lake. You will have information about previous visits so that you can plan around them.
What exactly is a GPS-fishfinder combo? GPS combos combine a GPS and fish finder into one device. They can vary in size from 7" to 16", and feature a color screen and built-in gps antennas. Some fish finders also have an internal sonar, including CHIRP or side imaging. Many are networkable. Lowrance and Simrad are popular brands.
Worldwide Basemap, Garmin’s standard offering, is what you need to start. It uses the same technology and features as their GPS land. Access to ocean maps and rivers, as well as streams, will all be available. You also have access to data about land such as airports, urban zones, and territorial borders.

A fish finder's screen size doesn’t have to dictate the choice of a device. I believe that a smaller screen is better for people who fish from small boats or kayaks. It is simpler to mount, operate and more durable than large equipment with 12-inch screens.
