Dolphin Pinger

we are the topmost supplier and trader of dolphin pinger in Porbandar, Gujarat, India. Dolphin Pingers work by emitting frequencies known to be audible to Whales, Dolphins and Porpoises. When Dolphin Pingers are placed on commercial fishing gear, Whales, Dolphins and Porpoises are alerted to the presence of the gear and entanglement can be avoided.

Scientific studies performed around the world over the past twenty years on different species and populations of Whales, Dolphins and Porpoises confirm that Pingers are highly effective in reducing incidental entanglement of these animals in fishing gear. The toothed Whales or Odontocetes (which includes Dolphin and Porpoise species) use an echo location system to help navigate their way in the oceans. By fitting Pingers to fishing gear, researchers believe that the Pings emitted stimulate Dolphins and Porpoise to echolocate, or send a signal to the Pingers and fishing gear, which is then returned to the cetaceans. The cetaceans are alerted to the gear the Pingers are attached to and entanglement is avoided. Porpoise Pinger was specifically designed to operate at 10 kHz which is the frequency with the longest track record of any signal for reducing Porpoise by-catch.
