Deeper Smart Sonar is a wireless, castable echo-sounder compatible with iOS and Android smartphones and tablets. Wi-Fi connection enabled to maximize both the distance between the sounder and the device holder up to 330 ft / 100 m and the depth range up to 260 ft / 80 m.
This is because the distance between the fish and the transducer changes as the boat passes over the fish (or the fish swims under the boat). When the fish enters the leading edge of the sonar beam, a display pixel is turned on. As the fish swims toward the centre of the beam, the distance to the fish decreases, turning on pixels at shallower ...

A kakivak, a fishing spear used by the Inuit. The third method is spear fishing. A large hole is cut in the ice and fish decoys may be deployed. The angler sits in a dark ice shanty called a ...
Biomass estimation is a method of detecting and quantifying fish and other marine organisms using sonar technology. [1] An acoustic transducer emits a brief, focused pulse of sound into the water. If the sound encounters objects that are of different density than the surrounding medium, such as fish, they reflect some sound back toward the source.
Today, commercial fishing vessels rely almost completely on acoustic sonar and sounders to detect fish. Fishermen also use active sonar and echo sounder technology to determine water depth, bottom contour, and bottom composition. Cabin display of a fish finder sonar
