Since the tablet cannot be connected to the internet while using the boat, as the Wi-Fi function is required for the echo sounder, it is important to download the map of the lake before using the boat.

To download the map of the lake, the tablet needs an internet connection, either through Wi-Fi at home or through a mobile hotspot when you're at the lake.

To download a map for offline use, you need to view it virtually. The 'Search for location' function is useful for finding the lake.

As soon as the map section is clear and sharp displayed, that part of the map is downloaded and stored for approximately 2-3 months by the map providers "Mapbox Satellite" and "Esri World Imagery.

Since only the visible section of the map and in the current zoom level is downloaded, it makes sense to virtually navigate through the lake in different zoom levels to download all the details and zoom levels. It also makes sense to download both the satellite and street views to have multiple viewing options while fishing.
