Let's start with the elephant in the room. This fish finder has GPS, it does have mapping, but it doesn’t have a MicroSD card slot. You are left with what comes with your fish finder unit. Garmin doesn't offer any additional mapping.
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.
There are many options when it comes to sonar, GPS and navigation. That's why I believe it is the best option. DualBeam is an excellent feature for anyone looking for side and down imaging. This will give you the best versatility on the sea.
Genesis Live mapping has some of the best features in the industry. C-Map contours can be viewed with high resolution detail. One-foot contours are also available for over 5,000 lakes in the United States. You can also fish in the Canadian Lakes if you are fishing up North. You will need an SD card to access the information.
Let me begin by talking about the elephant in a room. This fish finder doesn't have MicroSD slots, and it does not have GPS. It does have mapping. This means that the fish finder comes with everything and Garmin can't sell or download additional mapping.
This review is about GPS. Let's discuss it. It supports network compatibility. You can get live radar, camera, Bluetooth connectivity, smartphone connectivity, chartplotting and maps. All this can be done directly from the fishfinder.
GPS combos are very useful. The GPS fishfinder combo's map feature lets you plot areas in which you could catch fish. You can even save the places you've mapped out. A fish finder feature allows you save the fishing spots you've mapped out so that you can return to them later. A map can be used to help navigate you from one location to the next. With the depth gauge you can create waypoints.
