Deeper Sonars can be easily mounted onto boats, kayaks and float tubes using the Flexible Arm Mount. When fishing in Boat Mode you can create bathymetric maps of your fishing spots as you troll.

When operating in Boat Mode, the Deeper App instantly connects to the GPS in your smartphone or tablet and creates custom, real-time bathymetric maps, that you can see on the left side of the screen. To ensure the bathymetric maps you create in Boat Mode are accurate, make sure your Deeper Sonar is in close proximity to your smartphone or tablet, as it uses their GPS module.

Bathymetric maps are automatically saved and can be accessed later in the History section of the app. They will also be uploaded to your Lakebook account.

1. To use the feature, turn on Boat Mode (located in the upper menu bar in the main Settings field).

2. The mapping feature enables you to instantly monitor bottom contour detail and depth and locate the best fishing areas.

3. The white line on the map indicates the GPS record, while the color grade depicts the depth and underwater contours you are mapping.

4. To access records of your sonar scans and bathymetric maps, all with unlimited data storage, go to the History function located on the top menu bar.

ⓘ For the best experience while boat fishing, download the Offline Maps (find them in the Settings menu). If you haven’t downloaded Offline Maps, the Deeper App will use mobile data for map information, which can cause connectivity issues and mobile data charges.

ⓘ If you are returning to an area you have already mapped, you will see your previous bathymetry scans displayed on the map.

ⓘ You can map out new location or return to the ones you like best. Also, if you double click on a colored area of bathymetry on your map you will get information about the depth at that spot.
