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.
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 depths. When the fish swims directly under the transducer, it is closer to the boat so the stronger signal shows a thicker line.
Solunar tables are tables that fishermen and hunters use to determine the best days of the month and times of the day for catching fish and hunting game. Knowing the time of the tides, sunrise, and sunset help fishermen predict when fish are going to bite. For hunters, the tides are not a factor.
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
A scientific echosounder is a device which uses sonar technology for the calibrated backscatter measurement of underwater physical and biological components—this device is also known as scientific sonar. Applications include bathymetry, substrate classification, studies of aquatic vegetation, fish, and plankton, and differentation of water ...
