Pinger is acoustic instrument exclusively built to deter Dolphins approaching fishing nets and creating huge damages to nets and loss of catch. Pinger is designed to works by emitting a sound wave signal beyond 70 KHz that is known to be in the best hearing range of most Dolphin species. The signal acts as an alarm, and in some cases the Pinger stimulates Dolphins to use their echolocation which alerts them to the presence of the Pingers and fishing nets. Though this sound wave is not audible to human being but it create disturbance to Dolphins and results in checking approach of Dolphins near to fishing net. The Dolphin Pingers use a replaceable non rechargeable Lithium Ion battery. The batteries in the Dolphin Pinger will last 12 months based on everyday use for 12 hours per day.
