This step-by-step guide will help you quickly set up and start using your Deeper Spark. You will learn how to prepare the device, connect it to your smartphone, update firmware, and get ready for your first fishing session.
Step 1. Charge Your Deeper Spark
Connect your Deeper Spark to a USB power source using the provided cable. We recommend using a USB-C Power Delivery charger capable of supplying 20 V at 2 A minimum, this is equal to 40 W minimum power output. A suitable wall charger, such as a 65 W USB-C Power Delivery charger, can be purchased directly from us.
Wait until the device is fully charged - the LED indicators on the Spark battery will show when charging is complete.
If you are using the optional Spark Remote Controller, charge it separately before your session.
Step 2. Download Offline Maps (Recommended)
Open the Fish Deeper app while connected to your home Wi-Fi or mobile internet.
Open the Main menu (left side of the screen).
Go to Offline Maps → New Map.
Select and download the area where you plan to fish.
Tip: Downloading maps in advance ensures smooth mapping experience.
Step 3. Power On and Connect to Deeper Spark
Turn on your Deeper Spark (this can be done out of water).
Open your phone’s Wi-Fi Connections.
Connect to the Deeper Spark XXXX Wi-Fi network.
Open the Fish Deeper app and grant any required permissions.
Note: When connecting to your Deeper SPARK for the first time, the Fish Deeper app will automatically check for and install firmware updates.
Firmware updates must be performed while the SPARK is out of water
If no update starts, your device already has the latest firmware
It is normal if your phone shows that the Deeper Spark Wi-Fi network has no internet connection.

Important Tips
Before use, make sure all covers are tightly closed and sealed.
Keep your phone at least 1.2 m (4 ft) above the water for better connection stability.
Firmware updates should be performed while the Spark is out of water.
If no firmware update starts, your device already has the latest firmware version.
The Deeper Spark remote controller is not waterproof - it is only splash-resistant. Do not expose it to heavy rain, submerge it in water, or leave it in a very damp environment.
