Acoustic Locators - Teledyne Benthos

Teledyne Benthos provides a complete line of proven underwater locator products. Whether your requirements include search and recovery or underwater navigation and tracking, Teledyne Benthos has a solution to suit your needs. Our innovative locator devices fall into two general categories; pingers and transponders.

To locate and recover pingers, a diver with a handheld device (DPL) is dispatched to “listen” for, and home-in on the device. Shipboard listening devices are available as well. Transponders, like pingers, are attached to a mooring or other underwater item to be retrieved or located in the future.
