Once your Deeper sonar is mounted to your vessel, start moving across the water to scan or create underwater topography maps. Use Boat mode in the FishDeeper App (Settings > Boat Mode) for a split screen view of your scanning and mapping. We recommended speed limit of the boat is up to 5 km/h (2.7 knots).


 When trolling your Deeper sonar, keep your smartphone/tablet in a position where it can easily pick up the signal from your sonar. If your smartphone / tablet is on the floor of your boat or in your pocket, the connection may be unstable.
