Fish Deeper F.A.Q
Premium (Global bathymetry)
Fish Deeper Premium is a subscription-based service that provides access to global bathymetric maps on a smartphone, tablet, or personal computer. It will grant you instant access to over 50,000 global bathymetric maps.
Global bathymetry consists of bathymetric maps that provide detailed data on the depths of lakes, making them very useful for fishing planning - they help to understand the bottom terrain, its features and possible fish hotspots. Access to Global bathymetry is only granted if you have Fish Deeper Premium subscription.
Personal bathymetry is your personal bathymetric maps created by scanning water bodies with Deeper sonar.
How to enable Fish Deeper Premium (global bathymetric maps)?
If you have a Deeper Sonar device, you can claim Premium subscription of 3 months duration for each Deeper Sonar you own. When you activate Premium, you get access to global bathymetric maps. You can activate it here.
Worth to know:
You can claim Premium access for each of your Deeper sonar. The duration of all sonar subscriptions adds up, which means that if you have purchased two or more Deeper Sonars, you can claim 3 months subscription for each one of them.

What app features can I use with global bathymetric maps?
When you activate Premium in your account, global bathymetric maps will automatically appear in the Fish Deeper app or on the Fish Deeper website. You can also use the following features:

- Enable and disable the display of global or personal bathymetry in the map settings.
- Click on any point on the bathymetric map to find out the exact depth of that location.
- Save points of interest on the bathymetric map using the Catches and Marks function of the app.
- Use the lake search function.
How accurate are global bathymetric maps?
Global bathymetry is based on processed data: fully depersonalized sonar scan data is combined, processed, and compared with other relevant geographic data. Deeper UAB further processes this information, eliminating discrepancies and irrelevant data. Information processing is based on algorithms that evaluate many different aspects and include only data that is cross-checked. We are constantly improving these algorithms to eliminate inaccuracies and ensure the highest quality of bathymetric data.
Certain inaccuracies may still occur, such as those caused by seasonal changes in water levels or certain weather conditions.
Maps of locations (base maps) provided by external service providers may contain inaccuracies that may affect the display of global bathymetry (possible visual artifacts such as bathymetry overlapping with the shoreline). Third-party service providers also keep location maps up to date. If you find any inaccuracies in the bathymetric map or base map, please report it by email to [email protected]
I want a specific bathymetric map removed from Fish Deeper because it is a private or restricted lake.
If a particular lake is owned by you, and you wish its bathymetric data to be removed from the Fish Deeper global bathymetry, please email us at [email protected] with a proof of ownership, and we will arrange the map to be removed.
