How to Set-up and Use Deeper START?

Make sure your fish finder is fully charged. The Deeper Start charges in 2.5 hours and uses a USB cable that is compatible with any USB port. The battery lasts for 6 hours of continuous usage. Keep in mind that it isn’t necessary to use it continuously, unless you’re having fun scanning.


Use the barrel swivel to securely attach the fishing line to your Start fish finder. Place it in the water and it will automatically switch on. Connect to your fish finder via your phone settings. Then, open the Deeper App (make sure it’s up-to-date) to start scanning the water.

Important: Make sure you have turned off all Wi-Fi assistance on your smartphone (e.g., “Wi-Fi Assist” on iOS) or switch off Cellular Data altogether. This will ensure an uninterrupted connection.


Once connected, you’re ready to cast out. Your Start has a connection range of 165 ft. To ensure a solid connection, do not put your phone on the ground or in your pocket. We recommend using the Deeper smartphone mount for your rod.


Once your fish finder hits the water, you’ll start to see fish and depth data on your smartphone screen. Slowly reel in the fish finder and you will see changes in depth and fish location. If you don’t see any fish icons, that means there aren’t any fish! Try another spot until you find fish.

Important : The screen will scroll from right to left even if your sonar is stationary. That’s because your fish finder is constantly sending out scanning beams.
