KoçSavunma’s Pinger offers a reliable positioning solution for divers, submarines, unmanned underwater vehicles, and mission recorder devices. The pinger emits acoustic pings at specified frequencies and regular intervals, or in response to another signal. By listening to the ping signal, other surface or underwater elements can locate the element to which the pinger is affixed.
