Firstly, please bear in mind that the connection ranges of 100m / 330ft (PRO/PRO+) and 50m / 165ft (START) are maximum ranges and can only be achieved in perfect conditions and with a smartphone or tablet that has a strong reception antenna. Conditions like bad weather or using an incorrect attachment point may reduce the connection range.

To ensure a better connection range, first switch off Mobile Data on your smartphone / tablet, as this can affect the strength of your Wi-Fi signal. Mobile data strongly reduces the amount of information your device can send via its Wi-Fi connection.

 

For iPhones and iPads, it is very important to turn off the Wi-Fi assist feature as this feature can automatically switch off the connection with your Deeper. You can find this feature in the settings menu of your device.

Some Android phones have a similar feature, although the name of it may vary depending on the model of the phone. On Samsung phones, it is called Smart network switch. Other Android phones may have a similar feature with a different name. Please make sure that you turn off any settings that make your smartphone automatically disconnect from Wi-Fi networks with a poor internet connection. Other possible names for this feature include: Adaptive Wi-Fi / Auto Network Switch / Wi-Fi+.

 If you’re using any VPN services that may require a Wi-FI connection it is better to turn them off. If you don’t, the Deeper App may have difficulties connecting to the device automatically.

Do not to keep your smartphone or tablet on the ground while using the Deeper, as this can also reduce the strength of the signal. To maximize connectivity you should use the Deeper Smartphone Mount.

Please also note that it is only possible to connect to the Deeper using one smart device at a time. This means it will be impossible to connect to a Deeper Sonar if it is already connected to another phone or tablet. To switch off all current connections, simply take the Deeper out of the water, wipe it and wait for 5 minutes for the unit to turn off. Then, put it in the water again and connect.

If the device connects when on charge but does not connect when in the water, please check the water sensors on the bottom (the two metal points on the bottom housing of your Deeper). You can clean them by roughly scrubbing them with a sponge, or an electronic contact cleaner can be used if needed.

 

For the 3.0/PRO/PRO+ models only, make sure you are using the correct attachment point in order to ensure a stable. When fishing from a dock or bridge, screw your attachment bolt to the middle attachment point. Use the bottom attachment point if you're fishing from the shore. It is important that your Deeper does not tilt when being trolled or reeled. When it tilts, it scans the water surface rather than the bottom, giving inaccurate readings, and it’s Wi-Fi transmissions can be blocked, causing connectivity issues.

If these tips do not solve the issue, please reach out to the Deeper Support team.
