Smartphones have become "multi-tool" tools. Applications have revolutionized this digital world by meeting the needs of many activities, including fishing. Deeper hasn't missed the boat on this new technology by developing a fishfinder that receives and adjusts data from your smartphone. The Fish Deeper application is the essential link. Let's see how to use it correctly.


Home screen of the application
From left to right, you can see the time, sonar and phone battery levels, water temperature and depth at the time. In the middle, the sonar status.

By pressing the latter, you can pause the session or simply start a new one with the mode of your choice: standard, ice fishing, boat or shore fishing.

Sounder settings



Fishing modes
- Standard mode: the most basic mode. Access to bottom topography and fish only.
- Onboard GPS mode: mode that activates the GPS inside the sonar unit. A bathymetric chart will be created while giving the basic elements.
- Boat mode: mode that allows you to use the GPS on smartphone (sounder and bathymetric map). The speed of travel is also indicated.
- Ice fishing mode: usual display + ice fishing flashing which represents the topography on a circle format.

Sounder display
- Basic: level curve and fish detection only. Simplified view of the bottom and water layer. Grass beds are shown in green and fish are shown as icons.

- Detailed: the view is much more detailed and you can access many settings.

- Vertical flasher: advance shot of what is detected.

Detection angles
- Large: quite useful for finding fish. Image more difficult to decipher, because the cone can detect several contradictory elements.
- Narrow: more accurate. Very detailed image but very sensitive to sonar movements.
- Medium: good compromise between narrow and wide. Ideal for probing large areas while having a detailed image.

You can select automatic probe change (shallow water).

Sensitivity
It will control the amount of information you see on the screen. It's up to you to adjust this sensitivity according to your playground of the moment. The more noise there is (charged waterâ?¦), the more you have to reduce the sensitivity to see only the important information.

Fish icons
Retranscription via an algorithm that allows to analyze if the target is a fish or not. Be careful, the accuracy is not 100%, as you can imagine. As always, and this, whatever the sounder, there is a part of interpretation!

Color Palette
You can choose according to your visual comfort. This is rather personal. Possibility to zoom in and out with your fingers.




Night fishing
It is possible to use your Deeper at night. To continue to see where you launched it, you can turn on the LED. This can also be used as a marker or other feature.

Depth alarm
An audible alarm can be activated for a specified depth.
Display the distance of the sounder
Once activated, it lets you know the distance between you and the sonar unit. This feature is still experimental (GPS fishing from shore). Deeper is asking for feedback from its users to improve this feature.
GPS screen

For these two options you can even add a photo.

You can change the information at will by pressing your finger on the GPS point concerned.
- Diamond button
Allows you to choose what you want to display on the map: bathymetry, global and/or personal; marks, catches and/or locations, themselves specifiable.


Finally, on the GPS screen, the magnifying glass button allows you to search for a place and the arrow to locate the place where you are.
