Review on Portable WiFi Fish Finder with GPS for Kayaks, Boats, and Ice Fishing - Deeper PRO+ Smart Sonar for Deeper Insights by Mohamad Yusri ᠌

Nice and expensive toy. It did not affect the number of fish caught :-), unfortunately. A handy thing when exploring a reservoir, depth, bottom structure, when looking for fish. The sonar battery lasts for a long time (more than 5 hours), the phone sits down faster (mine went to zero in 3-4 hours), so mobile charging for the phone is a necessary thing. Pros below: Dimensions, mobility. Using a smartphone/tablet for display. Ability to create cartography. Work from the boat and from the shore. With its cons. - Price. - Expensive accessories. - In boat mode, there is no possibility to select a sonar GPS receiver, only the built-in GPS of the phone is used (there is a sensor in the sonar and in some cases it is more convenient to use it).
