The PowerSeeker Intelligent Fish Finder from PowerVision takes the guesswork out of locating fish. Cast or drop it on the water and the 2.7" fish finder turns on automatically, scans a 30° window and reports what it sees via Wi-Fi to your smartphone with the Vision+ app. The PowerSeeker shows the positions of fish and the contours of the underwater topography, measures depth from 2 to 262', and displays water temperature. It shuts off automatically one minute after being removed from the water and runs for four hours on a charge (charge time is 2.5 hours.) Use it from a boat or the shore.
