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

The echo sounder sensor is very sensitive, setting the sensitivity to 40% sonar clearly traced two devils tied 10 cm apart, one of which is the size of a match head, in the first screenshot it is clearly visible, there was a flock of bleak at the bottom. Thanks to the sonar readings shown in the second screenshot, I saw in advance how the fish approached the bait at that moment I poured tea), then you can see the hauling and, alas, the exit of the fish. The third screenshot just shows the perch activity at the bottom.
