Introducing FishSmart from Humminbird, the name you know and trust when it comes to finding fish. With the new Humminbird FishSmart app, you now have the ability to eliminate the unknown in fishing with: - High Definition Contour Lake Maps: For those who seek the best chart data out on the water, the new FishSmart app allows you to purchase detailed, incredibly-accurate contour maps of more than 1,500 detailed LakeMaster lakes directly within the app. You can also purchase maps for the app via the online ChartSelect store. - GPS Enabled Navigation: Know your exact location, speed and course out on the water, with GPS enabled navigation available in FishSmart directly through your smartphone. - Data Planning Tools: The new FishSmart app allows you to plan waypoints and routes to get a head start on your fishing trips. It also allows tracking on the water so you can save your tracks for future trips. - Data Sharing Tools: FishSmart allows you to import or export waypoints, routes and tracks in GPX format to share with your friends or transfer them to your Humminbird Chartplotter. - Map Sharing: Maps purchased on ChartSelect are exclusively available for use on both your Humminbird Chartplotter as well as in the FishSmart app. No extra map purchase required. The Humminbird Advantage: Already own lake maps with ChartSelect and want to use them on your smartphone? No problem! As an added benefit, all existing maps in your ChartSelect account are accessible for free within FishSmart once you download the app and sign-in to your account. Continued use of GPS running in the background can dramatically decrease battery life. For convenience, charts will be available for re-download for at least one year after purchase.
