Bathymetry is jumping to shore when using Boat mode.

In rare cases, you might see your bathymetry and boat track jumping to the shore when using Boat mode: This issue only concerns Android devices. It's caused by specific phone settings that interfere with the GPS signal. The issue with GPS happens because of a particular Google service setting that interferes with the app. Here's how you can prevent by adjusting those settings: Settings -> Location -> Google Location Accuracy -> Improve Location Accuracy = OFF Location -> Ad...

"Deeper Sonar is already connected to the Deeper Smart Sonar app" error

If you're trying to connect to your Deeper Sonar via the FishDeeper app, but getting the "Your Deeper Sonar is already connected to the Deeper Smart Sonar app" error, there could be 2 possible reasons for that: 1. Android and iOS devices: This can happen if you are using the old Deeper app (Deeper Smart Sonar app), and it's already connected to the Deeper Sonar. This will prevent the FishDeeper app from connecting. We strongly recommend deleting the Deeper Smart Sonar app, because it's an ou...

I cannot see my jig or fish during ice fishing

If you are unable to see your jig or see the movement of fish during ice fishing, please try the following: - Ensure that the Deeper is floating correctly and facing directly downwards. If it is tilted to the side, the sonar scanning cone may be going sideways and is unable to see the jig directly under it. If the sonar cone goes sideways, it may hit the sides of the ice hole and not reach the bottom. - Do not leave attachment bolts inserted into the Deeper, this may offset the center of...

How do I increase the battery life in very cold weather?

Lithium batteries can lose charge much faster when exposed to cold conditions. There are few steps you can take in order to protect your Deeper from cold, and as a result increase the battery life a) Take the Deeper out of the water whenever you're not using it, clean it from water and keep it in your pocket or somewhere warm. b) Water temperature in an ice hole is much warmer that the outside temperature. Furthermore, Deeper that is scanning an ice hole will heat up a bit, which also protects...

What to do if my data did not synchronize?

If data conversion is not successful you might get an error: Contact us through your application and we will sort it out. If you did not get a message but you can not see your scans on [Fish Deeper Website](https://maps.fishdeeper.com/en-ww), check if you have the latest app version.

To immediately upload any unsynced sessions, just hit the icon on the top right...

Sonar noise in ice fishing (thick ice)

Deeper PRO and PRO+ models will perform just fine in thick ice up to 1 meter (40 inches), however, some sonar noise may occur on the top of your screen. It occurs because some of the sonar waves reflect from the borders of the ice and may cause slightly incorrect readings on the top part of the sonar screen. This will not affect the depth or structure reading function of the Deeper, and you can easily mark fishes and even see your jig with no problem. Here's how you can reduce the amount of so...

Vertical lines on the sonar screen (sonar noise).

Vertical lines on the sonar screen means that your sonar is experiencing interference or crosstalk: If you see this type of readings it means that there is another sonar device running nearby. There are 2 solutions: - Move further away from the other sonar. This can help keeping the transducer cones from intersecting, but because cones get wider as the depth increases, in bigger depths the problem is harder to solve by positioning only. - If possible, change the frequency of one of the s...

Deeper shows fish icons in a pool / sink / bowl of water. There are no fishes in reality.

If you use the Deeper sonar in a tight artificial water tank (pool, sink, bowl of water, etc.) - it may show fish icons when in reality there are no fishes there. If you see something like that, there is no need to worry. What happens is that ultra-sound beam emitted by the Deeper gets reflected from the border of an artificial water tank, and the sonar is unable to process this ultra-sound properly. Thus, it gets confused and displays improper readings like "phantom" fishes or incorrect depth....

Short Bluetooth connection range (Deeper 3.0)

If you experience the short connection range issues, that's most likely because of not considering some of the small tips & tricks below. Please note that the maximum connection range of Deeper Bluetooth is 40-45 meters, which can be achieved in ideal conditions, thus, it can vary depending on the environment the Deeper is used in. First of all, check if you're using the right attachment bolt. When you fish from the dock, screw your attachment bolt to the middle hole. And please use the bottom ...

Does not activate when placed in the water (Deeper 3.0 / PRO / PRO+ / CHIRP)

First of all, please check the water sensors (two metal points on the Deeper) on the bottom of Deeper casing, if they are in a good condition. They are responsible for activating the Deeper. You should clean them up with a rough sponge to remove any rust or other residue on it. Afterward, you can check if it works by touching both of them (at the same time) with a wet finger - if you see a LED indication light up, seems that cleaning helped and the device will work in water. Alternatively, you ...

Deeper is connected, but no sonar readings

If you experience the 'no sonar readings' issue, first of all, you should check whether you have the latest version of the Deeper application installed or not. That can be checked by going to Google Play/App Store. Updating to the latest version of the application should help. If updating to the latest version of Deeper app does not help, please try restarting the application as well as the phone and connect to the Deeper again. That might help to re-initiate the scanning process and the Deeper...

Incorrect readings (depth, fish, temperature)

Usually incorrect readings (depth, fish, temperature) are caused by conditions of usage or improper use of the device. Incorrect readings may include: - Depth reading that is much higher than in reality; - Sonar noise - clutter of small dots or lines on the sonar screen; - Abnormal amount of fish detection; - “Too shallow or too deep (https://deepersonar.com/uk/en_gb/support/knowledgebase/entry/id/109)” message. Such issues can appear when ultra-sound cone of the Deeper is not d...

"Too shallow or too deep" error message.

If you're getting the "too shallow or too deep" error message, first of all check if the depth you're fishing at is sufficient for the Deeper. Fishfinder 3.0 / PRO / PRO+ Deeper models require at least 4.3 ft. (1.3 m) of depth to operate when using the Wide beam, and at least 2 ft (0.5 m) when using the Narrow beam. Deeper Start requires at least 1.6 ft (0.5 m.) of depth. Deeper CHIRP+ requires 6 in (0.15 m.) of depth in order to operate, when using Narrow CHIRP beam. It is also important to...
