There are many options for sonar, navigation, and GPS. This is why I believe it is the best choice. DualBeam sonar offers great down- and side imaging. This feature will give you the greatest flexibility on the water.
There are two types of GPS combos: fixed mount and portable. The portable version can either be attached to a boat's transom, or used with suction cups. A fish finder combo GPS can also be connected to your tablet or smartphone for easier navigation. Transducers make up the core of a GPS fishfinder combo. They emit and receive sound waves, which are converted to images on a display.

You may be able to customize the display by buying multiple chart cards with some units. You should choose a fishfinder that comes with preloaded charts cards. However, if your display needs to be updated, you have the option of purchasing additional chart cards. The other thing you should look at in a fishfinder is its accuracy and simpleness. You should be able to easily see contours on the color screen of your fish finder. High pixel displays should have glare adjustment and backlight.
Genesis Live mapping is one of the most advanced in the industry. C-Map contours are available with high-resolution detail. It also provides one-foot contours for more than 5,000 lakes throughout the country. It also includes 9,400 Canadian lakes if you fish up North. To access this information, however, you will need to purchase an optional SD card.
You don't always need to consider screen size when selecting a fishfinder. I believe that smaller screens are a plus for those fishing on smaller boats or kayaks. It's much easier to mount, to operate, and far less fragile than giant equipment with 12-inch screens.
There are many options available in terms of sonar and GPS. I find it to be the most versatile option. DualBeam sonar provides great side and down imaging. This will allow you to be as versatile on the water as possible.
