An experienced freelance writer, he previously obtained an English BA from the University of Saskatchewan, then spent over 20 years working in various markets as a television reporter, producer and news videographer. The development is similar to the development of ‘face recognition’ software in humans." The idea is that a series of the buoys/boxes could be arranged in a row offshore, running parallel to a beach. 0000277725 00000 n
Unlike them, it’s armed with an onboard computer running a sophisticated algorithm that allows it to isolate the presence of a shark by looking for specific patterns that correspond to a shark’s shape, size, and swimming technique in the sonar reading. Using a Tritech sonar? 0000317117 00000 n

They use sonar to detect the distinctive movement patterns made by sharks, and transmit a signal to alert lifeguards, who can raise the alarm warning beachgoers and swimmers.
Share . Like fish finders, the Clever Buoy uses a sonar system to detect the presence of animals in the water. Once movement has been detected, the data is analysed by Clever Buoy software to determine the size and species of the marine life, and ultimately if it is a threat. 0000288067 00000 n

While suspended nets do help keep the toothsome fish separated from swimmers, they're far from from 100 percent reliable, plus sharks (along with other marine animals) regularly get caught in them and perish – as sharks are one of the ocean's apex predators, removing them from the ecosystem could have disastrous consequences.
