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

Used mostly in winter. finds fish in the holes quickly. several times threw spinning along the riverbed. draws the bottom relief qualitatively, sees the fish. I liked this device. I bought a power bank for 20,000 for it, now everything is in order. Has pros: Compactness means mobility. ease of use on the pond without a boat. high accuracy of readings. additional functions. Cons below: a rather high price, the lack of definition of the size of the fish on the icon.
